Abstract

To reduce errors in the record of demand responses with respect to demand response requests.SOLUTION: A host control device calculates a consumer-based request power amount which is an allocated amount, of a requested power amount in a demand response, to each of demand response target systems. The host control device re-calculates the consumer-based requested power amount on the basis of the relationship between an estimated value of a demanded power amount and a target value of a consumer-based demanded power amount. The estimated value of the demanded power amount is estimated for a demand response target system in a demand response execution time period on the assumption that a rechargeable/dischargeable device in the demand response target system is not charged/discharged for the demand response, and is based on the state of the demand response target system at a time point after calculation of a baseline. The target value of the consumer-based demanded power amount is obtained by reflecting a requested power amount of each consumer, in a baseline of each consumer in the demand response target system.SELECTED DRAWING: Figure 4

In the demand response, the demand response request amount is a request for increase / decrease with respect to the baseline showing the power demand forecast for each customer's facility (= facility where the electric equipment controlled by the demand response is installed) at the time of executing the demand response. Shown as a quantity. At this time, the baseline includes the power consumption of a plurality of electric devices, but there is an error between the baseline and the actual result (actual power demand without demand response). In this case, even if the power consumption of the electric device is increased or decreased according to the demand response request amount, the error between the baseline and the actual result becomes the actual result error with respect to the demand response request.

Hereinafter, embodiments of the present invention will be described, but the following embodiments do not limit the inventions claimed. Also, not all combinations of features described in the embodiments are essential to the means of solving the invention.

FIG. 1 is a diagram showing an example of a device configuration of an electric power system according to an embodiment. With the configuration shown in FIG. 1, the electric power system 1 includes a higher-level control device 100 and a plurality of consumer installation systems 300. Each of the consumer installation systems 300 includes a lower control device 200. The upper control device 100 and the lower control device 200 communicate with each other. The host control device 100 also communicates with the external engine control device 910. The external engine control device 910 may be configured as a part of the electric power system 1 or may be configured as an external device of the electric power system 1.

The electric power system 1 plans and implements a demand response (DR). The electric power system 1 may further provide services other than demand response. The electric power system 1 may perform a plurality of services at the same time.
The service here is to carry out a certain purpose by adjusting the supply and demand of electricity. The power supply and demand adjustment referred to here may be the power supply and demand adjustment or the power supply and demand adjustment of the electric energy amount.

Further, in the following, a case where the upper control device 100, the lower control device 200, and the external engine control device 910 notify the amount related to the power supply and demand in units of electric energy such as watt hour (Wh) will be described as an example. .. However, the upper control device 100, the lower control device 200, and the external engine control device 910 may notify the amount of power supply and demand in units of electric power such as watts (W). Further, at least one of the upper control device 100, the lower control device 200, or the external engine control device 910 may convert the unit of electric power into the unit of electric energy.

The lower control device 200 is a device that controls the equipment of the electric power consumer, and notifies the upper control device 100 of the state information of the equipment of the electric power consumer. Further, the lower control device 200 controls the device for service execution such as demand response according to an instruction from the upper control device 100. Electric power consumers are also simply called consumers.
The lower control device 200 includes, for example, a power conditioning system (PCS) that controls a consumer's equipment and a computer that functions as a control unit of the power conditioning system. Alternatively, the power conditioning system may be configured as an external device of the lower control device 200, such as a power conditioning system being provided for each device to be controlled.

The consumer installation system 300 is a system composed of equipment used by the consumer. The individual consumer installation system 300 is configured as a system for supplying and demanding electric power and controlling the supply and demand of electric power in one consumer. However, the configuration of the consumer installation system 300 is not limited to a specific configuration. Further, the configuration of the customer installation system 300 may differ depending on the customer.
The consumer installation system 300 functions as a system for increasing or decreasing the power demand in the demand response. The customer installation system 300 is also referred to as a demand response implementation target system.
The number of the consumer installation system 300 included in the electric power system 1 may be one or more.

The upper control device 100 aggregates the state information of the consumer's equipment from the lower control device 200, calculates the service enablement amount, and notifies the external engine control device 910. Then, the upper control device 100 determines the service execution allocation amount for each customer in response to the service execution request from the external engine control device 910, and instructs the lower control device 200 of each customer to execute the service. ..

In particular, the host control device 100 calculates the feasible amount of the demand response and notifies the external engine control device 910 of the calculated feasible amount.
The host control device 100 calculates the amount of power demand that can be increased or decreased for the demand response as the feasible amount of the demand response. The feasible amount of demand response is also referred to as surplus capacity for demand response, or simply surplus capacity. The surplus capacity for increased demand response (demand response that increases power demand) is also called increased surplus capacity. The reserve capacity for lower demand response (demand response that reduces power demand) is also called the lower reserve capacity.

Further, the upper control device 100 determines the demand response request amount for each customer installation system 300 based on the demand response request amount (command value) instructed from the external engine control device 910, and the lower control device 200 determines the demand response request amount. Instruct to. In this way, the upper control device 100 assigns the demand response requested from the external engine control device 910 to the lower control device 200 and executes it.
The host control device 100 is configured by using a computer such as an EWS (Engineering Work Station).
The upper control device 100 is provided as a device used by, for example, a resource aggregator (RA).

A resource aggregator is a business operator that provides services by integrated control of electric power equipment on the consumer side. The resource aggregator provides a demand response service by integrating the amount of power supply and demand adjusted by consumers. Further, the resource aggregator may provide services other than demand response, such as providing frequency adjustment services by integrating the frequency adjustment capabilities of individual consumers with respect to the power system.

The external engine control device 910 receives a notification of the service implementation amount from the host control device 100, and notifies the service execution request amount to the host control device 100. In particular, the external engine control device 910 determines the demand response request amount by receiving the demand response enablement amount and the baseline notification from the host control device 100, and controls the demand response execution request including the determined request amount. Notify device 100.
The external engine control device 910 is configured by using a computer such as EWS.

FIG. 1 shows an example in which the external engine control device 910 is installed at the central power supply command center of the power transmission and distribution business operator. In this case, the resource aggregator acts as an aggregator that combines the resource aggregator and the aggregation coordinator (AC).
However, the user of the external engine control device 910 may be any user who is the target of providing the service by the electric power system 1, and is not limited to the power transmission and distribution business operator. For example, when an aggregation coordinator exists separately from the resource aggregator, the aggregation coordinator may use the external engine control device 910.

In the following, the whole power system 1 and the individual customer installation system 300 may be distinguished by the wording of "total" or "by customer". Specifically, the word "total" is added to the name indicating the entire power system 1. The wording "by customer" is added to the name indicating that the individual customer installation system 300 is related.

The demand response instructed by the host controller 100 from the external engine control device 910, that is, the demand response provided by the resource aggregator to the service provider, may be referred to as total demand response, demand response of the power system 1, or simply demand response. Refer to.
The baseline in the total demand response is also referred to as the total baseline, the baseline of the power system 1, or simply the baseline.

The feasible amount of the total demand response is also referred to as the total feasible amount of the demand response, the total feasible amount, or simply the feasible amount of the demand response, or the feasible amount. When the total demand response feasible amount is indicated by the electric energy, it is also referred to as the total demand response feasible electric energy, the total feasible electric energy, or simply the demand response feasible electric energy, or the feasible electric energy.

The total demand response request amount is also referred to as a total demand response request amount, a total request amount, or simply a demand response request amount, or a request amount. When the total demand response request amount is indicated by the electric energy amount, it is also referred to as the total demand response required electric energy amount, the total required electric energy amount, or simply the demand response required electric energy amount, or the required electric energy amount.
Further, the power demand amount of the power system 1 is also referred to as a total power demand amount or simply a power demand amount.

On the other hand, the demand response assigned to each lower control device 200 by the upper control device 100, that is, the lower control device 200 adjusts the power demand of the consumer installation system 300 for the demand response, that is, the demand response for each customer. Alternatively, it is also referred to as a demand response of the consumer installation system 300.
The baseline in the demand response for each consumer is also referred to as the baseline for each consumer or the baseline for the consumer installation system 300.

The feasible amount of demand response for each customer is the feasible amount of demand response for each customer, the feasible amount for each customer, the feasible amount of demand response of the customer installation system 300, or the customer installation system 300. Also referred to as the practicable amount of. When the demand response feasible amount for each customer is indicated by the electric energy, the demand response feasible electric energy for each customer, the feasible power amount for each customer, or the demand response feasible electric energy for the consumer installation system 300. Alternatively, it is also referred to as the feasible electric energy of the consumer installation system 300.

The demand response amount for each customer can be referred to as the demand response request amount for each customer, the demand response amount for each customer, the demand response request amount for the consumer installation system 300, or the demand amount for the consumer installation system 300. Refer to. When the demand response request amount for each consumer is indicated by the electric energy, the demand response required electric energy for each consumer, the required electric energy for each consumer, or the demand response required electric energy for the consumer installation system 300, or the demand. It is also called the required electric energy of the house installation system 300.
Further, the electric energy demand of one consumer installation system 300 is also referred to as the electric energy demand by each consumer or the electric energy demand of the consumer installation system 300.

FIG. 2 is a diagram showing an example of a device configuration in a consumer.
In the example of FIG. 2, the consumer installation system 300 includes a lower control device 200, a charge / discharge capable device 311, a photovoltaic power generation system 312, a load 313, and an XEMS 321. XEMS is a general term for energy management systems such as HEMS (Home Energy Management System), BEMS (Building Energy Management System), and FEMS (Factory Energy Management System).
Further, in the example of FIG. 2, a smart meter 930 is provided at an interconnection point between the power system 920, which is the power system of the power transmission and distribution business operator, and the consumer installation system 300. The smart meter 930 may be configured as a part of the consumer installation system 300, or may be configured as an external device of the consumer installation system 300.

The chargeable / discharging device 311 is a device capable of storing and discharging, for example, including a storage battery group. The chargeable / discharging device 311 corresponds to an example of a distributed energy resource (DER). The distributed power source referred to here is a power source provided in each consumer installation system 300. By consolidating the power supply and demand from the distributed power sources by the resource aggregator, it is possible to provide a relatively large-scale power supply and demand adjustment service to the service provider.

In the following, it is assumed that each of the consumer installation systems 300 of the consumers who participate in the demand response is equipped with the charge / discharge capable device 311. Since the consumer is equipped with the chargeable / discharging device 311, there is a difference between the power demand forecast (baseline for each customer) at the time of planning the demand response and the actual power demand (power demand for each customer). When it occurs, the power supply and demand can be adjusted by using the chargeable / discharging device 311.

Further, the charge power, the discharge power, the charge power amount, and the discharge power amount of the chargeable / dischargeable device 311 will be described with reference to the AC power or the converted value to the AC power amount in the lower control device 200 as the power conditioning system. When charging the chargeable / discharging device 311, a loss occurs during AC / DC conversion. Therefore, the DC charging power and the charging power amount after the AC / DC conversion are smaller than the AC charging power and the charging power amount before the conversion. Further, in the discharge of the chargeable / dischargeable device 311, a loss occurs at the time of DC / AC conversion. Therefore, the discharge power and the discharge power amount of the AC after the DC / AC conversion are smaller than the discharge power and the discharge power amount of the DC before the conversion.

The photovoltaic system 312 is shown as an example of a device that produces electric power and includes a solar cell to convert sunlight into electric power.
However, the device that generates electric power is not indispensable for the consumer installation system 300. Further, when the consumer installation system 300 includes a device for generating electric power, the device is not limited to the photovoltaic power generation system 312. For example, the consumer installation system 300 may include, or in place of, the photovoltaic power generation system 312, a private power generator such as a fuel cell or a Cogeneration or Combined Heat And Power.

The load 313 consumes power. The load 313 may be composed of one device. Alternatively, a plurality of devices may be included in the load 313. Further, the type of the device constituting the load 313 is not limited to a specific type.
The chargeable / discharging device 311, the photovoltaic power generation system 312, and the load 313 are collectively referred to as a consumer device group 310.

XEMS321 is a device that provides energy management services for consumers. For example, the XEMS 321 instructs the power conditioning system of the lower control device 200 to control the device for implementing the energy management service.
Further, the XEMS 321 functions as a terminal device in the consumer installation system 300. For example, the XEMS 321 displays information about service execution and accepts user operations such as setting operations related to service execution. All or part of XEMS 321 may be configured to be portable, such as being provided on a smartphone. Alternatively, a terminal device may be provided separately from the XEMS321. In that case as well, the terminal device may be configured to be portable, such as being provided on a smartphone.

By controlling the consumer equipment group 310 in conjunction with the XEMS321 and the lower control device 200, the control of the consumer equipment group 310 for demand response (demand response for each customer) and other than demand response such as energy management service. The control of the consumer equipment group 310 for the service of the above can be carried out at the same time.
The XEMS 321 and the lower control device 200 may be configured as one device, or may be configured as separate devices.

The smart meter 930 measures the electric power at the position where the smart meter 930 itself is installed. For example, the electric power measured by the smart meter 930 is used for billing the consumer. However, the arrangement of the smart meter is not limited to the position shown in FIG. Smart meters can be placed where power measurements are required to implement the service.

FIG. 3 is a diagram showing an example of setting a unit time in the demand response. In the following, a case where the demand response start time (supply and demand adjustment start time) is set to the hour (0 minutes per hour) and the hour 30 minutes will be described as an example.
In this case, each of the 30 minutes divided by the hour and 30 minutes per hour is the unit time in the demand response. Each unit time is also called a frame. In addition, the frame for which the demand response is to be performed is referred to as "frame (i)", and "frame (i-1)", "frame (i-2)", ..., "Frame" is traced back from the frame (i). (Im) ”(m is a positive integer).

For example, in the case of a demand response to be implemented from 13:00 to 13:30, 30 minutes from 13:00 to 13:30 is frame (i), and 30 minutes from 12:30 to 13:00 is frame. (I-1), 30 minutes from 12:00 to 12:30 is the frame (i-2), 30 minutes from 11:30 to 12:00 is the frame (i-3), and so on. Become.

Further, in the example of FIG. 3, one hour before the start time of the frame for executing the demand response (start time two frames before) is set to Gate Close (GC).
The demand response service provider (resource aggregator) notifies the service provider (for example, the power transmission and distribution business operator or the aggregation coordinator) of the baseline and the demand response enablement amount before the gate is closed. .. The service provider determines the demand response request amount for the notified baseline within the range of the demand response enablement amount. The service provider notifies the service provider of the determined request amount and requests the implementation of the demand response.
For example, in the configuration of FIG. 1, information on the baseline and the amount of demand response that can be performed is transmitted from the host control device 100 to the external engine control device 910 before the gate is closed. Further, the external engine control device 910 transmits a demand response request amount by the time the gate is closed.

After the baseline and enablement notification deadline, the baseline and demand response enablement settings cannot be changed. In addition, the demand response request amount cannot be changed after the gate is closed. Therefore, after the gate is closed, neither the baseline nor the demand response request amount can be changed.

The unit time of the demand response in the power system 1 is not limited to 30 minutes shown in FIG. 3, and may be set to a fixed time. The demand response start time is not limited to the hour and 30 minutes per hour, and may be determined according to the unit time of the demand response.
The length of time per frame is also referred to as the frame length. In the example of FIG. 3, the frame length is 30 minutes.

Further, the time from the gate closing to the start of demand response execution is not limited to one hour, and may be a predetermined time.
The gate close is the "deadline for submitting the supply and demand plan from the grid user (power generation company or retail electricity company) to the grid operator", and means the time when transactions in the wholesale electricity market are stopped. .. In the following explanation, the term gate close is also used to mean the time when the baseline used in the demand response cannot be changed.

FIG. 4 is a schematic block diagram showing an example of the functional configuration of the upper control device 100. In the configuration shown in FIG. 4, the host control device 100 includes a first communication unit 110, a first storage unit 180, and a first control unit 190. The first control unit 190 includes a customer-specific information acquisition unit 191, an overall information calculation unit 192, a consumer-specific baseline calculation unit 193, a total required electric energy acquisition unit 194, and a customer-specific electric energy requirement calculation unit. It is equipped with 195.

The first communication unit 110 communicates with another device. In particular, the first communication unit 110 receives information about the state of the consumer installation system 300 including the lower control device 200 from each of the lower control devices 200. Further, the first communication unit 110 transmits to the lower control device 200 a request for executing a demand response for each customer to the customer installation system 300 including the lower control device 200.

The demand response implementation request for each consumer transmitted by the first communication unit 110 may include a request for which the value of the required electric energy for each customer is 0. By setting the value of the required electric energy for each consumer to 0, the consumer installation system 300 can stop charging / discharging for demand response.

Further, in the demand response execution request for each customer transmitted by the first communication unit 110, the amount of electric power for which charging / discharging for the demand response is stopped for a certain customer installation system 300 is added to the other. It may be included that is reflected in the amount of electric power required for each consumer for the consumer installation system 300 of the above. As a result, the charge / discharge stop portion for the demand response in the certain consumer installation system 300 can be reflected in the charge / discharge power of the other consumer installation system 300. Therefore, charging / discharging for demand response in a certain consumer installation system 300 can be stopped without changing the amount of power demand of the entire power system 1.

Further, the first communication unit 110 transmits the demand response enablement amount and the baseline information to the external engine control device 910. Further, the first communication unit 110 receives a demand response execution request from the external engine control device 910.
The first communication unit 110 corresponds to an example of transmission means.

The first storage unit 180 stores various information. The first storage unit 180 is configured by using the storage device included in the host control device 100.
The first control unit 190 controls each unit of the upper control device 100 to perform various processes. The function of the first control unit 190 is executed by the CPU (Central Processing Unit) included in the upper control device 100 reading a program from the first storage unit 180 and executing the program.

The customer-specific information acquisition unit 191 describes the amount of power demanded by the consumer installation system 300, the amount of stored power and free capacity of the chargeable / discharging device 311 included in the consumer installation system 300, and the charging / discharging of the chargeable / discharging device 311. Acquires information on the state of the consumer installation system 300, such as measured values. Specifically, the consumer-specific information acquisition unit 191 extracts information on the state of the consumer installation system 300 including the lower control device 200 from the signal received by the first communication unit 110 from the lower control device 200.

The free capacity of the chargeable / discharging device 311 here is the amount of electric power that can be charged before the charging / discharging device 311 is fully charged. For example, the customer-specific information acquisition unit 191 may calculate the free capacity as a value obtained by subtracting the stored power amount from the rated capacity of the chargeable / discharging device 311.

The overall information calculation unit 192 calculates information regarding the overall status of the electric power system 1 based on the information regarding the status of the individual consumer installation system 300 acquired by the consumer-specific information acquisition unit 191. In particular, the overall information calculation unit 192 is based on the actual value of the electric energy demand of the individual consumer installation system 300, and the electric energy demand of all the consumer installation systems 300 included in the electric power system 1 at the time of executing the demand response. Calculate the baseline (total baseline), which is the predicted value of. Further, the overall information calculation unit 192 calculates the demand response enablement amount of the entire power system 1 in the demand response execution based on the charge / discharge possible amount of each charge / discharge possible device 311.

Here, the dischargeable amount (dischargeable power amount) of the chargeable / dischargeable device 311 in a predetermined time (for example, one frame) is restricted by both the stored power amount and the rated discharge power of the chargeable / dischargeable device 311. .. Specifically, the dischargeable amount of the chargeable / dischargeable device 311 in a predetermined time is the stored power amount of the chargeable / dischargeable device 311 or the rated discharge power of the chargeable / dischargeable device 311 for a predetermined time length (for example, coma). The smaller of the electric energy obtained by multiplying the length).

Further, when the reverse power flow from the consumer installation system 300 to the power system 920 is not recognized, the dischargeable amount of the chargeable / discharging device 311 in a predetermined time is assumed to be that the charging / discharging device 311 does not charge / discharge. It is also restricted by the amount of power demanded by each consumer at the specified time. In this case, the dischargeable amount of the chargeable / dischargeable device 311 in a predetermined time is the amount of stored power of the chargeable / dischargeable device 311, the amount of power obtained by multiplying the rated discharge power of the chargeable / dischargeable device 311 by the length of the predetermined time, or It is the smaller of the amount of power demanded by each consumer in a predetermined time when it is assumed that the chargeable / discharging device 311 does not charge / discharge.

Further, the chargeable amount (chargeable electric power) of the chargeable / discharging device 311 in a predetermined time is limited by both the free capacity and the rated charging power of the chargeable / discharging device 311. Specifically, the chargeable amount of the chargeable / discharging device 311 in a predetermined time is the free capacity of the charging / discharging device 311 or the rated charging power of the chargeable / discharging device 311 multiplied by the length of the predetermined time. Whichever is smaller.
On the other hand, when the chargeable / discharging device 311 charges, reverse power flow from the consumer installation system 300 to the power system 920 does not occur. Therefore, there is no restriction on the amount of power demanded by each consumer with respect to the amount of chargeable amount of the chargeable / discharging device 311 in a predetermined time.

In addition, the information acquisition unit 191 for each consumer calculates a predicted value of the electric energy demand for each consumer based on the actual data of the electric energy demand for each consumer. In particular, the customer-specific information acquisition unit 191 assumes that the charge / discharge possible device 311 does not charge / discharge for the demand response for each of the customer installation systems 300, and the demand response execution time (demand response). Calculate the predicted value of the amount of power demand by consumer in the implementation time zone). Assuming that the charge / discharge possible device 311 does not charge / discharge for demand response, the predicted value of the power demand by consumer during the demand response implementation time is calculated as the demand by consumer when demand response is not implemented. Also called an electric energy predicted value.

The customer-specific information acquisition unit 191 is based on the state of the customer installation system 300 at a time after the baseline is calculated (for example, after the gate is closed), and the demand power demand by customer when the demand response is not executed is assumed. Calculate the quantity prediction value. The information acquisition unit 191 for each consumer may repeat the process, for example, every minute, to calculate the predicted value of the electric energy demand for each consumer when the demand response is not executed.
In the following description, unless otherwise specified, when the host control device 100 uses the predicted value of the demand power amount for each consumer when the demand response is not executed, the latest one obtained at that time is used.

If the information acquisition unit 191 for each customer assumes that the chargeable / discharging device 311 does not charge or discharge at all as the predicted value of the demand power amount for each customer when the demand response is not executed, the demand power for each customer is assumed. The amount may be calculated.
For example, in the case of the configuration of FIG. 2, the consumer-specific information acquisition unit 191 sets the total value of the measured electric energy of the load 313 and the measured electric energy of the photovoltaic power generation system 312 as the non-implementation of the demand response. It may be calculated as a predicted value of electric energy demand for each consumer.

Alternatively, the information acquisition unit 191 for each consumer uses the actual value of the electric energy demand only for the frames whose charge / discharge possible device 311 is not charging / discharging for the demand response, and the demand for each consumer when the demand response is not executed. Even if the electric energy forecast value is calculated, it is possible to calculate the electric energy demand forecast value for each consumer when the demand response is not executed.
Alternatively, the consumer-specific information acquisition unit 191 charges / discharges for demand response with respect to the actual value of power demand for each consumer of the coma in which the charge / discharge possible device 311 charges / discharges for demand response. You may increase or decrease (cancel) the amount of electric power of.

The consumer-specific baseline calculation unit 193 calculates the consumer-specific baseline. The customer-specific baseline is a breakdown corresponding to the allocation of the total baseline calculated by the overall information calculation unit 192 to each of the customer installation systems 300.
The consumer-specific baseline calculation unit 193 corresponds to an example of a consumer-specific baseline calculation means.
The total required electric energy acquisition unit 194 acquires the total required electric energy. The total required electric energy is the required amount of electric energy increase / decrease with respect to the total baseline, which is a predicted value of the electric energy required of all the consumer installation systems 300 included in the electric energy system 1. The required power amount referred to here is a required amount of increase / decrease in the required power amount in the demand response. In the case of increased demand response, the required power amount is the amount of increase in the required power amount. In the case of lowered demand response, the required power amount is the amount of decrease in the required power amount.
The total required electric energy acquisition unit 194 extracts information indicating the total required electric energy from the signal received by the first communication unit 110 from the external engine control device 910. However, strictly speaking, it is restricted by the contract amperage of the consumer (the so-called power that the circuit breaker trips).

The demanded electric energy calculation unit 195 for each consumer calculates the required electric energy for each consumer. The required electric energy for each consumer is an allocation amount for which the total required electric energy is allocated to each of the consumer installation systems 300. When the total required electric energy acquisition unit 194 acquires the total required electric energy, the customer-specific required electric energy calculation unit 195 allocates the total required electric energy to each of the consumer installation systems 300.
The demanded electric energy calculation unit 195 for each consumer corresponds to an example of the required electric energy calculation means for each consumer.

The method by which the demanded electric energy calculation unit 195 for each consumer allocates the total electric energy demand to each of the consumer installation systems 300 is not limited to a specific one. For example, the demanded electric energy calculation unit 195 for each consumer may calculate the required electric energy for each consumer based on each contract amperage of the consumer installation system 300 (demand for the contracted amperage of the target consumer). Proportional distribution using the ratio divided by the total contract amperage of the entire house). Alternatively, the demanded electric energy calculation unit 195 for each consumer calculates the required electric energy for each consumer based on the rated capacity of the chargeable / dischargeable device 311 provided in each of the consumer installation systems 300, the stored power amount, and the free capacity. (The larger the value of free space, etc., the larger the amount of power required by each customer is allocated, etc.). Alternatively, the demanded electric energy calculation unit 195 for each consumer may further calculate the required electric energy for each consumer based on the baseline for each consumer (the larger the value of the baseline for each consumer, the more the consumer. Allocate a large amount of different required power, etc.).

The demanded electric energy calculation unit 195 for each consumer may update the required electric energy for each consumer. Since the total required electric energy cannot be changed after the gate is closed, the demanded electric energy calculation unit 195 for each consumer is the total value of the required electric energy for each consumer for all the consumer installation systems 300 included in the electric power system 1. Increase or decrease the amount of power required by each individual consumer so that the total amount of power required remains constant.

Here, each of the consumer installation systems 300 assumes that the consumer-specific baseline and the customer-specific demand response are not implemented (charge / dischargeable device 311 charges for purposes other than demand response). If there is a difference in the demand power amount for each customer in the demand response execution time (frame (i)), the demand response execution time is charged and discharged so as to eliminate the difference. The possible device 311 is charged and discharged.

Assuming that the demand response for each customer is not implemented, the amount of power demand for each customer is, for example, in the case of the configuration of FIG. 2, the amount of power generated by the solar power generation system 312 is subtracted from the power consumption of the load 313. , It is calculated by adding or subtracting the charge / discharge electric energy of the charge / discharge possible device 311 for applications other than the demand response for each customer. Of the charge / discharge electric energy of the charge / discharge possible device 311, the charge / discharge electric energy for applications other than the demand response for each customer is added when charging and subtracted when discharging.

The consumer-specific baseline corresponds to the predicted value of the demand power amount for each customer in frame (i) before the gate is closed, assuming that the demand response for each customer is not implemented. On the other hand, if it is assumed that the demand response for each customer will not be implemented due to changes in the power consumption due to changes in the usage status of the load 313, changes in the power generation amount of the solar power generation system 312 due to changes in the weather, etc. The amount of power demand by consumer in coma (i) can change. As a result, there may be a difference between the baseline for each consumer and the amount of power demand for each consumer in the demand response execution time when it is assumed that the demand response for each consumer is not executed.

The difference between the baseline for each consumer and the amount of power demand for each consumer in the demand response execution time when it is assumed that the demand response for each consumer is not executed is also called the prediction error of the baseline for each consumer. Eliminating the difference between the consumer-specific baseline in the demand response by consumer and the power demand by consumer in the demand response implementation time when it is assumed that the demand response is not executed is to eliminate the difference in the demand power amount by consumer. It is also called to compensate for the prediction error.

Specifically, the charge / discharge of the charge / discharge possible device 311 compensates for the prediction error of the baseline for each consumer. To compensate for the error, the charge / discharge possible device 311 charges / discharges in order to eliminate the error between the demand in the demand response for each customer (corresponding to the baseline for each customer + the required electric energy for each customer) and the actual result. It can be said that. The amount of power demand before error compensation is based on the assumption that the charge / discharge device 311 does not charge or discharge for error compensation (however, the charge / discharge device 311 is used for applications other than demand response). It is assumed that the discharge is continuing), but it is the amount of power demand by consumer.

Even if each of the consumer installation systems 300 charges / discharges the chargeable / dischargeable device 311 so that the demand power amount for each customer during the demand response execution time (i-frame) becomes the demand power amount target value for each customer. good. The target value of the electric energy demanded by the consumer here is the electric energy that reflects the electric energy demanded by the consumer in the baseline by the consumer.

Reflecting the required power amount in the baseline power amount here means increasing or decreasing the required power amount from the baseline by the amount of the required power amount. In the case of lowered demand response, the required power amount target value can be obtained by subtracting the required power amount from the baseline. For example, when the demand response for each customer is increased and the demand response is increased, the required power amount for each customer is added to the baseline for each customer.
On the other hand, in the case of increased demand response, the required power amount target value can be obtained by adding the required power amount to the baseline. For example, when the demand response for each customer is lowered and the demand response is low, the amount of power required for each customer is subtracted from the baseline for each customer.

In this way, each of the consumer installation systems 300 charges and discharges the chargeable / dischargeable device 311 so that the demand power amount for each customer during the demand response execution time becomes the demand power amount target value for each customer. The charge / discharge possible device 311 can be charged / discharged so as to compensate for the prediction error of the home-specific baseline.
In this case, of the charge / discharge electric energy of the chargeable / dischargeable device 311, the charge / discharge electric energy for demand response is the charge / discharge electric energy for achieving the required electric energy for each consumer and the baseline for each consumer. It can be said that it is the total electric energy with the charge / discharge electric energy for compensating for the prediction error.

On the other hand, there is a limit to the amount of power that can be charged / discharged by the charge / discharge device 311. If the prediction error of the baseline for each customer cannot be filled with the charge / discharge of the charge / discharge possible device 311, the amount that cannot be filled is the required amount and the actual value in the demand response for each customer of the customer installation system 300. It will be an error.

On the other hand, the demanded electric energy calculation unit 195 for each customer calculates the required electric energy for each customer as the predicted value of the electric energy required for the consumer installation system 300 (the predicted electric energy demanded by the customer when the demand response is not implemented). ), It is possible to reduce the error between the required amount and the actual value in the demand response for each customer of the customer installation system 300. By reducing the error between the required amount and the actual value in the demand response for each customer, it is possible to reduce the error between the required amount and the actual value in the total demand response.

Further, when the chargeable / discharging device 311 charges for the demand response for each customer, a loss occurs in each of the AC / DC conversion at the time of charging and the DC / AC conversion at the time of discharging the charged electric power. If the amount of electric power that can be charged / discharged by the charge / discharge device 311 can be reduced, such loss can be reduced.

Here, the charge / discharge performed by the charge / discharge possible device 311 for the demand response for each customer may be in the opposite direction to the increase / decrease in the total demand power amount in the total demand response. For example, while the total demand response is lowered and the demand response is low, the chargeable / dischargeable device 311 may charge for the demand response for each customer. If such charging is stopped and the discharge power amount of the other chargeable / dischargeable device 311 that discharges is reduced by that amount, the charge / discharge power amount of the entire power system 1 is not affected, without affecting the total power demand amount. Can be reduced.

Therefore, the demanded electric energy calculation unit 195 for each consumer stops the charging / discharging possible device 311 from charging for the demand response for each consumer when the total demand response is lowered and the demand response is reached. The case where the estimated value of power demand by consumer when the demand response is not implemented is smaller than the target value of power demand by consumer corresponds to the case where the chargeable / discharging device 311 charges for demand response by customer. do.

When the customer-specific electric energy calculation unit 195 updates the customer-specific electric energy requirement of the consumer installation system 300, the customer-specific electric energy target value is set for each customer when demand response is not expected to be implemented. The required electric energy for each consumer may be calculated so as to be the predicted electric energy demand value. Specifically, the demanded electric energy calculation unit 195 for each consumer may set the required electric energy for each consumer to 0 for the corresponding customer installation system 300.
As a result, the demand power calculation unit 195 for each consumer sets the charge / discharge possible device 311 by the lower control device 200 in order to set the demand power amount for each consumer at the demand response execution time as the target value for the demand power amount for each customer. Stop charge / discharge control.

In addition, the demand response calculation unit 195 for each consumer stops the charging / discharging device 311 from charging for the demand response for each consumer when the total demand response is lowered and the demand response is reached. Therefore, the amount of discharge power of the chargeable / dischargeable device 311 that discharges is reduced. Therefore, the customer-specific electric energy demand calculation unit 195 reduces at least one consumer-specific electric energy requirement of the consumer installation system 300 including the chargeable / dischargeable device 311 that discharges for demand response.

At that time, the demand electric energy calculation unit 195 for each consumer tells that at least one consumer in the consumer installation system 300 whose predicted value of the electric energy demand for each consumer when the demand response is not implemented is larger than the baseline for each consumer. Alternatively, the required electric energy may be reduced.
In the consumer installation system 300, where the predicted value of power demand by consumer is larger than the baseline by consumer when demand response is not implemented, in order to match the power demand by consumer with the target value of power demand by consumer. It is considered that the amount of discharge power required is large. For this reason, in the consumer installation system 300 in which the predicted value of the electric energy demand by consumer is larger than the baseline by consumer when the demand response is not implemented, the dischargeable amount is lowered as the demand response by consumer. There is a relatively high possibility that the amount of discharge power required for the system will be insufficient. As described above, this shortage becomes an error between the required amount and the actual value in the demand response of the consumer installation system 300.

On the other hand, the demanded electric energy calculation unit 195 for each consumer reduces the required electric energy for each consumer, so that the target value for the electric energy for each consumer is set to the predicted value (demand response) for the electric energy required for the consumer installation system 300. It is possible to approach the predicted value of power demand by consumer at the time of non-implementation assumption). As a result, as described above, it is possible to reduce the error between the required amount and the actual value in the demand response of the entire power system 1.

Further, the demanded electric energy calculation unit 195 for each consumer stops the charge / discharge possible device 311 from discharging for the demand response for each consumer when the total demand response is increased and the demand response is reached. The case where the predicted value of the demand power amount for each consumer when the demand response is not implemented is larger than the baseline for each consumer corresponds to the case where the chargeable / discharging device 311 discharges for the demand response for each customer.
In this case as well, when the customer-specific electric energy calculation unit 195 updates the customer-specific electric energy requirement of the consumer installation system 300, the customer-specific electric energy target value is assumed to be non-demand response implementation. The demanded electric energy for each consumer may be calculated so as to be the predicted value of the electric energy demanded for each consumer. Specifically, the demanded electric energy calculation unit 195 for each consumer may set the required electric energy for each consumer to 0 for the corresponding customer installation system 300.

In addition, when the total demand response is increased and the demand response is increased, the demand energy calculation unit 195 for each consumer stops the charge / discharge possible device 311 from discharging for the demand response for each consumer, so that the demand response is increased. Therefore, the amount of charging power of the chargeable / discharging device 311 to be charged is reduced. Therefore, the customer-specific electric energy demand calculation unit 195 reduces at least one consumer-specific electric energy requirement of the consumer installation system 300 including the chargeable / dischargeable device 311 that charges for demand response.

At that time, the demand electric energy calculation unit 195 for each consumer tells that at least one consumer in the consumer installation system 300 whose predicted value of the electric energy demand for each consumer when the demand response is not implemented is smaller than the baseline for each consumer. Alternatively, the required electric energy may be reduced.
In the consumer installation system 300, where the predicted value of power demand by consumer is smaller than the baseline by consumer when demand response is not implemented, in order to match the power demand by consumer with the target value of power demand by consumer. It is considered that the amount of charging power required is large. For this reason, in the consumer installation system 300 in which the predicted value of the power demand amount for each customer is smaller than the baseline for each customer when the demand response is not implemented, the chargeable amount is increased as the demand response for each customer. There is a relatively high possibility that it will be insufficient for the amount of charging power required for. As described above, this shortage becomes an error between the required amount and the actual value in the demand response of the consumer installation system 300.

On the other hand, the demanded electric energy calculation unit 195 for each consumer reduces the required electric energy for each consumer, so that the target value for the electric energy for each consumer is set to the predicted value (demand response) for the electric energy required for the consumer installation system 300. It is possible to approach the predicted value of power demand by consumer at the time of non-implementation assumption). As a result, as described above, it is possible to reduce the error between the required amount and the actual value in the demand response of the entire power system 1.

FIG. 5 is a schematic block diagram showing an example of the functional configuration of the lower control device 200. With the configuration shown in FIG. 5, the lower control device 200 includes a second communication unit 210, a second storage unit 280, and a second control unit 290. The second control unit 290 includes a power demand information acquisition unit 291, a charge / discharge information acquisition unit 292, a charge / discharge prediction unit 293, a customer-specific target value acquisition unit 294, and a charge / discharge control unit 295.

The second communication unit 210 communicates with another device. In particular, the second communication unit 210 transmits information regarding the state of the consumer installation system 300 including the second communication unit 210 itself to the host control device 100. Further, the second communication unit 210 receives a demand response execution request from the host control device 100 to the consumer installation system 300 including the second communication unit 210 itself.
For example, the second communication unit 210 receives the demand response execution request including the demanded electric energy for each customer and the baseline for each customer. The second communication unit 210 may receive a demand response execution request that further includes information indicating whether the demand response is an increased demand response or a decreased demand response.
The second communication unit 210 corresponds to an example of acquisition means.

The second storage unit 280 stores various information. The second storage unit 280 is configured by using the storage device included in the lower control device 200.
The second control unit 290 controls each unit of the lower control device 200 to perform various processes. The function of the second control unit 290 is executed by the CPU included in the lower control device 200 reading a program from the second storage unit 280 and executing the program.

The electric power demand information acquisition unit 291 acquires the electric energy demand for each consumer of the consumer installation system 300 including the electric power demand information acquisition unit 291 itself. For example, the electric power demand information acquisition unit 291 may integrate the electric power demand at the interconnection point measured by the smart meter 930 and calculate the electric energy demand measurement value for each consumer.
The charge / discharge information acquisition unit 292 acquires information regarding the state of the charge / discharge possible device 311. For example, the charge / discharge information acquisition unit 292 may calculate the charge power amount and the discharge power amount by integrating the measured values of the charge / discharge power of the charge / discharge possible device 311 for each of charge and discharge. Further, the charge / discharge information acquisition unit 292 may acquire information on the stored power amount of the charge / discharge possible device 311.

The charge / discharge prediction unit 293 predicts the charge / discharge state of the charge / discharge possible device 311 in, for example, a peak shift, based on the information of the electric power charge for each time zone. Specifically, the charge / discharge prediction unit 293 charges the charge / discharge capable device 311 for peak shift during the time when the electricity charge is low, and discharges for the peak shift during the time when the electricity charge is high. Predict.
As a result, it is expected that the charge / discharge prediction unit 293 can predict the charge / discharge state of the charge / discharge possible device 311 with relatively high accuracy.

The demand response provider may determine the required power amount in the demand response based on the prediction result of the charge / discharge state of the charge / discharge possible device 311 by the charge / discharge prediction unit 293. For example, the overall information calculation unit 192 may predict the demand response enablement amount at the time of demand response execution based on the prediction result of the charge / discharge state of the charge / discharge possible device 311 by the charge / discharge prediction unit 293. Then, the demand response provider may determine the required power amount in the demand response within the range of the demand response feasible amount.

The customer-specific target value acquisition unit 294 acquires the customer-specific power demand target value. As described above, the target value of the power demand amount for each consumer is the target value of the power demand amount for each customer when the demand response for each customer is implemented. The customer-specific target value acquisition unit 294 calculates the demand-specific electric energy target value by reflecting the demanded electric energy for each customer in the electric energy of the baseline for each customer.
The customer-specific target value acquisition unit 294 corresponds to an example of a customer-specific target value acquisition means.

The charge / discharge control unit 295 controls the charge / discharge of the charge / discharge possible device 311. In particular, the charge / discharge control unit 295 controls the charge / discharge of the charge / discharge possible device 311 so that the demand power amount for each consumer during the demand response execution time is matched with the demand power amount target value for each customer. Specifically, the charge / discharge control unit 295 charges / discharges the charge / discharge possible device 311 with a power amount corresponding to the difference between the demand power amount for each consumer and the demand power amount target value for each customer during the demand response execution time. .. As a result, the charge / discharge control unit 295 makes the demand power amount for each consumer including the charge / discharge power amount of the charge / discharge possible device 311 a target value for the power demand amount for each customer.
The charge / discharge control unit 295 corresponds to an example of the charge / discharge control means.

Further, the charge / discharge control unit 295 may stop the charge / discharge control for causing the charge / discharge possible device 311 to charge for the demand response for each customer when the total demand response is lowered and the demand response is obtained. Therefore, the customer-specific target value acquisition unit 294 considers the power amount of the consumer-specific baseline based on the customer-specific power demand amount updated by the consumer-specific power demand calculation unit 195 described above. The charge / discharge control unit 295 may calculate the electric energy demand target value for each consumer and control the charge / discharge of the charge / discharge possible device 311 based on the electric energy demand target value for each consumer.

Further, when the total demand response is lowered and the demand response is reached, the charge / discharge control unit 295 discharges the charge / discharge possible device 311 in response to the suspension of charging for the demand response for each customer in the other customer installation system 300. The amount of power may be reduced. Regarding this point as well, the consumer-specific target value acquisition unit 294 considers the customer-specific baseline electric energy based on the updated consumer-specific electric energy required by the consumer-specific electric energy calculation unit 195 described above. Then, the electric energy demand target value for each consumer may be calculated, and the charge / discharge control unit 295 may control the charge / discharge of the charge / discharge possible device 311 based on the electric energy demand target value for each consumer.

In particular, when the charge / discharge possible device 311 discharges and the predicted value of the electric energy demand for each customer when the demand response is not executed is larger than the baseline for each customer, the charge / discharge control unit 295 charges / discharges. The amount of discharge power of the possible device 311 may be reduced. Regarding this point as well, the consumer-specific target value acquisition unit 294 considers the customer-specific baseline electric energy based on the updated consumer-specific electric energy required by the consumer-specific electric energy calculation unit 195 described above. Then, the electric energy demand target value for each consumer may be calculated, and the charge / discharge control unit 295 may control the charge / discharge of the charge / discharge possible device 311 based on the electric energy demand target value for each consumer.

Further, the charge / discharge control unit 295 may stop the charge / discharge control for causing the charge / discharge possible device 311 to perform discharge for the demand response for each customer when the total demand response is increased and the demand response is obtained. Regarding this point as well, the consumer-specific target value acquisition unit 294 considers the customer-specific baseline electric energy based on the updated consumer-specific electric energy required by the consumer-specific electric energy calculation unit 195 described above. Then, the electric energy demand target value for each consumer may be calculated, and the charge / discharge control unit 295 may control the charge / discharge of the charge / discharge possible device 311 based on the electric energy demand target value for each consumer.

Further, when the total demand response is increased and the demand response is increased, the charge / discharge control unit 295 charges the charge / discharge possible device 311 in response to the cancellation of the discharge for the demand response for each customer in the other customer installation system 300. The amount of power may be reduced. Regarding this point as well, the consumer-specific target value acquisition unit 294 considers the customer-specific baseline electric energy based on the updated consumer-specific electric energy required by the consumer-specific electric energy calculation unit 195 described above. Then, the electric energy demand target value for each consumer may be calculated, and the charge / discharge control unit 295 may control the charge / discharge of the charge / discharge possible device 311 based on the electric energy demand target value for each consumer.

In particular, when the charge / discharge possible device 311 charges and the predicted value of the power demand for each customer when the demand response is not executed is smaller than the baseline for each customer, the charge / discharge control unit 295 charges / discharges. The charging power amount of the possible device 311 may be reduced. Regarding this point as well, the consumer-specific target value acquisition unit 294 considers the customer-specific baseline electric energy based on the updated consumer-specific electric energy required by the consumer-specific electric energy calculation unit 195 described above. Then, the electric energy demand target value for each consumer may be calculated, and the charge / discharge control unit 295 may control the charge / discharge of the charge / discharge possible device 311 based on the electric energy demand target value for each consumer.

Further, in the simultaneous execution of the peak shift and the demand response, the charge / discharge control unit 295 sets the upper limit value set for at least one of the charge power for the peak shift and the discharge power for the peak shift. Based on this, the charge / discharge of the charge / discharge possible device 311 may be controlled.
As a result, when the charge / discharge possible device 311 is performing charge / discharge for peak shift, it is possible to leave a margin for further charging / discharging for demand response for each customer.

Whether the upper control device 100 or the lower control device 200 determines whether the charge / discharge performed by the charge / discharge possible device 311 for the demand response for each customer is in the opposite direction to the increase / decrease in the total demand power amount in the total demand response. You may do it.
When the host control device 100 makes the determination, the charge / discharge performed by the charge / discharge possible device 311 for the demand response for each customer by the customer-specific power demand calculation unit 195 is the total demand power amount in the total demand response. The value of the required electric energy for each customer for the customer installation system 300 determined to be in the opposite direction to the increase / decrease in the above is set to 0. Then, the first communication unit 110 transmits the required electric energy for each consumer to each of the consumer installation systems 300.
In the lower control device 200, the charge / discharge control unit 295 controls the charge / discharge of the charge / discharge possible device 311 according to the required power amount for each customer set to 0, so that the charge / discharge possible device 311 can be used for demand response. Charging and discharging can be stopped.

When the lower control device 200 determines whether or not the charge / discharge performed by the charge / discharge possible device 311 for the demand response for each customer is in the opposite direction to the increase / decrease in the total demand power amount in the total demand response, the lower control device 200 controls the upper control. The device 100 transmits information indicating whether the total demand response is an increased demand response or a decreased demand response to each of the lower control devices 200. In the lower control device, the second communication unit 210 receives information indicating whether the total demand response is an increased demand response or a decreased demand response.

Then, in the lower control device 200, for example, whether or not the charge / discharge performed by the charge / discharge possible device 311 for the demand response for each customer in the charge / discharge control unit 295 is opposite to the increase / decrease in the total demand power amount in the total demand response. To judge. If it is determined that the charge / discharge performed by the charge / discharge device 311 for the demand response for each customer is in the opposite direction to the increase / decrease in the total power demand in the total demand response, the charge / discharge for the demand response is stopped. In addition, the charge / discharge of the charge / discharge possible device 311 is controlled.

Further, the second communication unit 210 transmits information indicating that charging / discharging for demand response has been stopped to the host control device 100. As a result, the consumer-specific electric energy calculation unit 195 of the host control device 100 reflects the electric energy required for the charge / discharge stop in the electric energy required for each consumer for the other consumer installation system 300. Another required power amount can be recalculated.

Then, the charge / discharge performed by the charge / discharge possible device 311 for the demand response for each customer, which is performed by either the upper control device 100 or the lower control device 200, causes an increase / decrease in the total demand power amount in the total demand response. "Judgment of whether or not the direction is reversed" shall be executed after the calculation time of the baseline and before the actual demand response implementation time starts, using the estimated value of the demand power amount for each consumer when the demand response is not executed. Is desirable. However, either the upper control device 100 or the lower control device 200 may make this determination based on the state of the consumer installation system 300 after the demand response execution time has entered.

For example, in order to execute the demand response for each consumer, the lower control device 200 predicts the electric energy demand for each consumer during the demand response execution time (the integrated electric energy for each consumer from the start to the end of the demand response). The charge / discharge of the charge / discharge possible device 311 may be controlled by the feedback control that brings the predicted value) closer to the target value of the electric energy demand for each customer.

Then, the lower control device 200 determines whether or not the increase / decrease in the power demand amount for each consumer due to the charge / discharge performed by the charge / discharge possible device 311 and the increase in the total power demand amount in the total demand response are in opposite directions. May be good. That is, the distinction between the increase or decrease of the power demand amount for each consumer due to the charge / discharge performed by the lower control device 200 to the charge / discharge possible device 311 and the distinction of the increase or decrease of the total power demand amount in the total demand response can be made. It may be decided whether or not it is the opposite.

Next, the calculation of the baseline will be described with reference to FIGS. 6 and 7.
FIG. 6 is a diagram showing an example of the timing at which the host control device 100 acquires data for baseline calculation. The overall information calculation unit 192 of the host controller 100 predicts the power demand of all the consumer installation systems 300 included in the power system 1 during the demand response execution time (frame (i)) based on the actual power demand. Is calculated and set as the total baseline.

Regarding the actual power demand, the power demand information acquisition unit 291 of the lower control device 200 repeatedly acquires the power demand amount at the interconnection point from the smart meter 930, for example, every minute. Then, the power demand information acquisition unit 291 increases the power demand integrated value [Wh] at the interconnection point for 30 minutes of the frame length of the finished frame every time the frame ends (hourly or every 30 minutes per hour). Is calculated. The unit is indicated by [].
The integrated value of the electric power demand at the interconnection point calculated by the electric power demand information acquisition unit 291 corresponds to the measured value of the electric energy demand for each consumer in the corresponding frame of one consumer installation system 300. The electric power demand information acquisition unit 291 transmits the calculated electric energy demand for each consumer to the host control device 100 via the second communication unit 210.

The customer-specific information acquisition unit 191 of the upper control device 100 obtains the average of the latest 6 frames from the current time to 3 hours ago for the measured value of the customer-specific electric energy acquired from the lower control device 200. Calculate the average value of the amount of electricity demanded by each house per frame.
The information acquisition unit 191 for each consumer uses the average value of the electric energy demand for each consumer for the demand forecast to reduce the influence when the measured value of the electric energy for each consumer changes accidentally. Can be done. As a result, it is expected that the prediction of the baseline (total baseline) for the total electric energy demand obtained by the overall information calculation unit 192 based on the electric energy demand for each customer will be relatively high accuracy.

According to the customer-specific information acquisition unit 191, for example, among the latest 6 frames, the charge / discharge state of the charge / discharge possible device 311 of the customer installation system 300 to be calculated is the same as the current charge / discharge state. Only the amount of power demand may be used as the target for calculating the average value. That is, the information acquisition unit 191 for each consumer indicates the average value of the power demand amount in the frame in which the chargeable / discharging device 311 is only charging, or the power demand in the frame in which the charging / discharging device 311 is only discharging. Either one of the average values of the quantities may be calculated.
As a result, it is possible to predict the power demand amount with relatively high accuracy when the charge / discharge possible device 311 continues the current charge / discharge state.

Alternatively, the consumer-specific information acquisition unit 191 determines the power demand of the consumer installation system 300 in the latest predetermined number of frames, including both the charging time and the discharging time of the chargeable / discharging device 311. The average value of the quantity per frame may be calculated. As a result, it is possible to cope with the case where the charge / discharge enable device 311 is expected to repeatedly switch the charge / discharge between the current time and the demand response start time.
Further, the time for the host control device 100 to use the data for calculating the average value is not limited to 3 hours, and may be a predetermined number of frames (predetermined time).

The overall information calculation unit 192 of the host control device 100 totals the average value of the power demand for each customer for all the customer installation systems 300 included in the power system 1 and calculates the total power demand for each frame. do.
FIG. 6 shows an example in which the host control device 100 calculates the average value of all the power demands of the latest 6 frames. In the example of FIG. 6, the first communication unit 110 of the upper control device 100 sets the power demand amount of the consumer installation system 300 in the frame (i-3), which is the latest past frame, to the lower level of the consumer installation system 300. Received from the control device 200. The first storage unit 180 has already received and stored the power demand amount in the frames before that. Then, the customer-specific information acquisition unit 191 calculates the average value of the electric power demand amount of the consumer installation system 300 in the latest 6 frames from the frame (i-8) to the frame (i-3).

The host control device 100 sets the calculated average value as a consumer-specific baseline for each consumer installation system 300 in the demand response that can be activated one hour (two frames later) from the current time.
Further, the overall information calculation unit 192 sums the calculated baselines for each consumer installation system 300 for all the consumer installation systems 300 included in the electric power system 1, and the overall baseline for the entire electric power system 1 (total baseline). ) Is calculated.
FIG. 6 shows an example in which the gate close is set 30 minutes (one frame before) before the demand response start time. The host control device 100 calculates the total baseline and transmits it to the external engine control device 910, for example, two frames before the start of the demand response.

However, the method in which the host control device 100 calculates the total baseline is not limited to the above method. For example, the host controller 100 may calculate the total baseline using a known baseline calculation method. Then, the host control device 100 may allocate the total baseline to each of the consumer installation systems 300 to calculate the consumer-specific baseline. In this case, various criteria such as the contracted amperage of each consumer or the rated capacity of the chargeable / discharging device 311 can be used as the criteria for allocating the total baseline to each of the consumer installation systems 300.

FIG. 7 is a diagram showing an example of a processing procedure in which the power system 1 calculates a baseline. The lower control device 200 and the upper control device 100 perform the processing of FIG. 7 before closing the gate, for example, the coma (i-3).
In the process of FIG. 7, the smart meter 930 repeats, for example, every minute, measures the demand power of the consumer installation system 300 at the interconnection point, and transmits it to the lower control device 200 (sequence S111).

In the lower control device 200, the electric power demand information acquisition unit 291 integrates the electric power demand of the consumer installation system 300 and calculates the electric energy demand for each customer for one frame (for example, the integrated value for 30 minutes) (sequence). S112). The electric power demand information acquisition unit 291 calculates the electric energy demand for each frame.
The second communication unit 210 transmits the power demand amount for one frame calculated by the power demand information acquisition unit 291 to the host control device 100 each time the frame ends (sequence S121).
When the smart meter continuously outputs only the value of the integrated electric energy, the integrated electric energy (for example, 10235 [kWh]) at the start time of the corresponding frame (for example, 11:30) is set to the end time of the corresponding frame (for example, 12). By subtracting from the integrated electric energy (for example, 10500 [kWh]), the electric energy demand for each customer of the corresponding frame (for example, 265 [kWh]) can be calculated.

In the host control device 100, the consumer-specific baseline calculation unit 193 calculates the consumer-specific baseline (sequence S131). For example, as described with reference to FIG. 6, the information acquisition unit 191 for each consumer calculates the average value of the electric energy demand for each consumer per frame as the baseline for each consumer for each customer installation system 300. ..

Next, the overall information calculation unit 192 of the host control device 100 calculates the total baseline, and the first communication unit 110 transmits the obtained total baseline to the external engine control device 910 (sequence S132). For example, the overall information calculation unit 192 calculates the total of the baselines for each consumer for all the consumer installation systems 300 included in the electric power system 1 as the total baseline.
After the sequence S132, the power system 1 ends the process of FIG.

Next, the calculation of the demand response possible amount will be described with reference to FIG.
FIG. 8 is a diagram showing an example of a processing procedure in which the power system 1 calculates a demand response possible amount. The power system 1 performs the process of FIG. 8 as well as the process of FIG. 7 before closing the gate.
In the process of FIG. 8, the charge / dischargeable device 311 repeats, for example, every minute, and the state information such as the stored power amount of the charge / dischargeable device 311 itself and the measured value of the charge / discharge power of the charge / dischargeable device 311 itself ( Alternatively, it may be a measured value of the charge / discharge power amount) is transmitted to the lower control device 200 (sequence S211).

In the lower control device 200, the charge / discharge information acquisition unit 292 acquires the stored power amount and free capacity information based on the information from the charge / discharge possible device 311 and integrates the charge power and the discharge power (sequence S212). ). When the measured value of the charge / discharge power amount is sent, the charge / discharge information acquisition unit 292 acquires the measured charge power amount and the discharge power amount.

The stored power amount and free capacity of the chargeable / discharging device 311 may be assigned to each service. In this case, the charge / discharge information acquisition unit 292 subtracts the stored power amount and free capacity allocated to applications other than the demand response for each customer from the stored power amount and free capacity of the chargeable / dischargeable device 311. The amount of stored power and the free capacity that can be used for another demand response may be calculated.

The charge / discharge information acquisition unit 292 subtracts the amount of power allocated to applications other than the demand response for each customer, such as BCP (Business Continuity Plan), from the amount of stored power of the chargeable / dischargeable device 311. The amount of stored power that can be used may be calculated.
The charge / discharge information acquisition unit 292 acquires information on the amount of stored power and the free capacity at that time each time the frame ends. The charge / discharge information acquisition unit 292 may acquire information on the amount of stored power and the amount of free capacity with higher frequency information.

Further, the charge / discharge information acquisition unit 292 integrates the charge power of the charge / discharge power of the charge / discharge possible device 311 and calculates the charge power amount for one frame. The charge / discharge information acquisition unit 292 integrates the discharge power of the charge / discharge power of the charge / discharge possible device 311 and calculates the discharge power amount for one frame. When the measured value of the charge / discharge power amount is sent, the charge / discharge information acquisition unit 292 uses the measured charge power amount and the discharge power amount for one frame as the calculated value.
The second communication unit 210 outputs each information of the stored power amount, the free capacity, the charging power amount for one frame, and the discharging power amount for one frame of the chargeable / discharging device 311 to the host control device 100 every time the frame ends. (Sequence S221).

In the host control device 100, the consumer-specific information acquisition unit 191 calculates the average charge power amount per frame and the average discharge power amount per frame for each customer installation system 300 (sequence S231). The customer-specific information acquisition unit 191 charges the latest predetermined frame, for example, the latest 6 frames from the current time to 3 hours ago, based on the charge power amount and the discharge power amount for each frame acquired from the lower control device 200. Calculate the average electric energy value and the average electric energy discharge value.

Then, the customer-specific information acquisition unit 191 calculates a charge power amount prediction value and a discharge power amount prediction value from the current time to the demand response start time for each customer installation system 300 (sequence S232). For example, when the number of frames from the current time to the demand response start time is two, the customer-specific information acquisition unit 191 uses a value obtained by doubling the average charging power amount per frame as the charging power amount prediction value. It may be calculated. Similarly, the customer-specific information acquisition unit 191 may calculate a value obtained by doubling the average value of the discharge power amount per frame as the discharge power amount prediction value.

Next, the customer-specific information acquisition unit 191 calculates the chargeable amount and the dischargeable amount of the chargeable / discharging device 311 at the demand response start time for each customer installation system 300.
As described above, the chargeable amount and the dischargeable amount of the chargeable / dischargeable device 311 depend on the stored power amount of the chargeable / dischargeable device 311. The amount of power that can be charged by the chargeable / dischargeable device 311 is limited to the free capacity obtained by subtracting the stored power amount from the rated capacity. Further, the amount of electric power that can be discharged by the chargeable / discharging device 311 is limited to the amount of electricity stored or less.
The rechargeable amount that depends on the stored power amount of the chargeable / discharging device 311 is also referred to as a rechargeable amount based on the stored amount or a rechargeable amount (stored amount). The dischargeable amount that depends on the stored power amount of the chargeable / dischargeable device 311 is also referred to as a dischargeable amount based on the stored amount or a dischargeable amount (stored amount).

Further, as described above, the chargeable amount and the dischargeable amount of the chargeable / dischargeable device 311 also depend on the rated charge power and the rated discharge power of the chargeable / dischargeable device 311. The amount of power [Wh] that can be charged by the chargeable / dischargeable device 311 in one frame is limited to the amount of power obtained by multiplying the rated charge power [W] of the chargeable / dischargeable device 311 by the frame length [h]. Further, the amount of power [Wh] that the chargeable / dischargeable device 311 can discharge in one frame is limited to the amount of power obtained by multiplying the rated discharge power [W] of the chargeable / dischargeable device 311 by the frame length [h].

The rechargeable amount that depends on the rated charge power of the chargeable / dischargeable device 311 is also referred to as a rechargeable amount based on the rating or a rechargeable amount (rated). The dischargeable amount that depends on the rated discharge power of the chargeable / dischargeable device 311 is also referred to as a dischargeable amount based on the rating or a dischargeable amount (rated).
Further, the rechargeable amount considering both the rechargeable amount based on the stored amount and the rechargeable amount based on the rating is also referred to as a total rechargeable amount or a rechargeable amount (total). The dischargeable amount considering both the dischargeable amount based on the stored amount and the dischargeable amount based on the rating is also referred to as a total dischargeable amount or a dischargeable amount (total).

In the example of FIG. 8, the consumer-specific information acquisition unit 191 estimates the chargeable amount based on the chargeable amount of the chargeable / dischargeable device 311 and the dischargeable amount based on the stored amount for each customer-installed system 300 (sequence S233). ). Further, the customer-specific information acquisition unit 191 estimates the chargeable amount based on the rating of the chargeable / dischargeable device 311 and the dischargeable amount based on the rating for each customer installation system 300 (sequence S234). Then, the customer-specific information acquisition unit 191 estimates the total chargeable amount and the total dischargeable amount of the chargeable / dischargeable device 311 for each customer installation system 300 (sequence S235).
However, the consumer-specific information acquisition unit 191 may perform the processing of the sequence S234 before the processing of the sequence S233.

Regarding the estimation of the chargeable amount (storage amount) (sequence S233), the customer-specific information acquisition unit 191 determines from the chargeable amount (storage amount) of the chargeable / dischargeable device 311 at the current time to the demand response start time from the current time. The remaining amount of power obtained by subtracting the predicted charging power amount is estimated as the chargeable amount (storage amount) at the demand response start time.
The customer-specific information acquisition unit 191 can charge at the demand response start time by using the free capacity transmitted by the lower control device 200 in sequence S221 as the chargeable amount (storage amount) of the chargeable / dischargeable device 311 at the current time. The amount (storage amount) may be estimated. When the lower control device 200 transmits the free space available for the demand response for each customer in the sequence S221, the information acquisition unit 191 for each customer has the free space available for the demand response for each customer at the demand response start time. May be estimated as the rechargeable amount (storage amount).

Regarding the estimation of the dischargeable amount (storage amount) (sequence S233), the customer-specific information acquisition unit 191 determines from the dischargeable amount (storage amount) of the chargeable / dischargeable device 311 at the current time to the demand response start time from the current time. The remaining amount of power obtained by subtracting the predicted discharge power amount is estimated as the dischargeable amount (storage amount) at the demand response start time.
The consumer-specific information acquisition unit 191 uses the stored power amount transmitted by the lower control device 200 in sequence S221 as the dischargeable amount (stored amount) of the chargeable / dischargeable device 311 at the current time, and discharges at the demand response start time. The possible amount (storage amount) may be estimated. When the lower control device 200 transmits the amount of stored power that can be used for the demand response for each customer in the sequence S221, the information acquisition unit 191 for each customer can use the stored power that can be used for the demand response for each customer at the demand response start time. The amount of electric power may be estimated as the amount that can be discharged (the amount of electricity stored).

In this way, the consumer-specific information acquisition unit 191 separately calculates the charge power amount predicted value and the discharge power amount predicted value from the current time to the demand response start time. Then, the consumer-specific information acquisition unit 191 uses the estimated value of the chargeable power amount for estimating the chargeable amount, and uses the estimated value of the discharge power amount for estimating the dischargeable amount. As a result, both the chargeable amount and the dischargeable amount are calculated to be smaller than the case where the estimated value of the charge / discharge power amount that does not distinguish between charge and discharge is used. At this point, the consumer-specific information acquisition unit 191 can estimate the chargeable amount and the dischargeable amount on the safe side.

Regarding the estimation of the dischargeable amount based on the rating (sequence S234), the consumer-specific information acquisition unit 191 estimates the dischargeable amount based on the rating of the chargeable / dischargeable device 311 based on the equation (1).

Regarding the estimation of the rechargeable amount based on the rating (sequence S234), the consumer-specific information acquisition unit 191 estimates the rechargeable amount based on the rating of the chargeable / discharging device 311 based on the equation (2).

Regarding the estimation of the total dischargeable amount (sequence S235), the consumer-specific information acquisition unit 191 has an estimated dischargeable amount based on the stored amount estimated in the sequence S233 and a dischargeable amount based on the rating estimated in the sequence S234. Compare with the estimated value (based on Equation 1). Then, the consumer-specific information acquisition unit 191 estimates that the smaller of the estimated dischargeable amount based on the amount of electricity stored and the estimated dischargeable amount based on the rating is the total dischargeable amount at the demand response start time. do.

Regarding the comprehensive chargeable amount estimation (sequence S235), the consumer-specific information acquisition unit 191 has a chargeable amount estimated value based on the stored storage amount estimated in the sequence S233 and a chargeable amount based on the rating estimated in the sequence S234. Compare with the estimated value (based on Equation 2). Then, the consumer-specific information acquisition unit 191 estimates that the smaller of the chargeable amount estimated value based on the stored amount and the chargeable amount estimated value based on the rating is the total chargeable amount at the demand response start time. do.

Next, the customer-specific information acquisition unit 191 increases the lower demand response possible amount (lower demand response possible amount for each customer) and the higher demand response possible amount (upper demand response possible amount for each customer) for each customer installation system 300. To get.
Specifically, the customer-specific information acquisition unit 191 describes the total dischargeable amount [Wh] of the chargeable / dischargeable device 311 at the demand response start time and the demand in the frame (i) for each customer installation system 300. Compare with the home baseline [Wh]. Then, the consumer-specific information acquisition unit 191 sets the value of the total dischargeable amount or the consumer-specific baseline, whichever is smaller, in the demand response execution time (frame (i)) of the consumer installation system 300. Calculated as the reduced demand response possible amount [Wh] (reduced demand response possible amount for each customer). As described above, under the constraint that the consumer installation system 300 cannot reverse power flow to the power system 920, the power demand cannot be reduced beyond the consumer-specific baseline, which is the predicted value of the power demand. Is.

On the other hand, when the chargeable / discharging device 311 charges, reverse power flow from the consumer installation system 300 to the power system 920 does not occur. Therefore, the customer-specific information acquisition unit 191 can increase the total chargeable amount of each consumer installation system 300 at the demand response start time as it is at the demand response execution time of the consumer installation system 300. It is used as the amount (the amount that can be increased by the customer and the demand response is possible).

Next, the overall information calculation unit 192 calculates the increase demand response possible amount and the decrease demand response possible amount of the entire power system 1 and transmits them to the external engine control device 910 via the first communication unit 110 (sequence S237). ..
The overall information calculation unit 192 calculates the amount of increased demand response for each consumer installation system 300, the total amount of electric power for all the consumer installation systems 300 included in the electric power system 1, and the entire electric power system 1 in the frame (i). It is calculated as the increased demand response possible amount in, that is, the total increased demand response possible amount. Further, the overall information calculation unit 192 adds the amount of reduced demand response possible for each customer installation system 300 to the total amount of power for all the consumer installation systems 300 included in the power system 1, and the power system 1 in the frame (i). It is calculated as the total reduced demand response possible amount, that is, the total reduced demand response possible amount.
After the sequence S237, the power system 1 ends the process of FIG.

FIG. 9 is a diagram showing an example of the notification timing of the baseline, the demand response possible amount, and the demand response command in the power system 1.
In the example of FIG. 9, as in the case of FIG. 8, the gate is closed 30 minutes before the demand response start time. The host controller 100 sets the total baseline, the total up-demand response possible amount, and the total down-demand response possible amount to the external engine control device 910 before the gate close, for example, up to 45 minutes before the demand response start time. Notify to.

The service providing target person (or the service providing target system) determines the demand response request amount within the range of the demand response possible amount notified by the host control device 100. The service providing target person (or the service providing target system) inputs the determined demand response request amount to the external engine control device 910 as the amount of electric power that increases or decreases from the baseline. The external engine control device 910 notifies the host control device 100 of the demand response command including the input demand response request amount by one frame before the demand response start time (when the gate is closed in the example of FIG. 9).

In the case of the lowered demand response, the host control device 100 receives the demand response start time (estimated time for invoking the demand response) and the total lowered demand response request amount with respect to the total baseline from the external engine control device 910. At this time, the external engine control device 910 notifies the external engine control device 910 of the total power amount for one frame (0.5 hours) of the demand response execution time as the total lower demand response request amount. A value equal to or less than the lower demand response possible amount is transmitted to the upper control device 100.

FIG. 10 is a diagram showing an example of a processing procedure in which the electric power system 1 calculates a target electric energy for each consumer installation system 300 based on the total demand response command value from the external engine control device 910.
In the process of FIG. 10, the external engine control device 910 transmits a demand response command to the host control device 100 (sequence S311). The external engine control device 910 transmits either a lower demand response command including a total lower demand response request amount or a higher demand response command including a total higher demand response request amount.

In the host control device 100 that has received the demand response command, the demand electric energy calculation unit 195 for each consumer requests the customer installation system 300 based on the latest status information of each of the consumer installation systems 300 at that time. The required electric energy for each consumer is determined (sequence S321).

When the demand response requested by the external engine control device 910 is a lowered demand response, the customer-specific power demand calculation unit 195 sets the total reduced demand response request amount from the external engine control device 910 to each of the consumer installation systems 300. Assign to. As a result, the demanded electric energy calculation unit 195 for each consumer determines the required electric energy for each consumer (required amount for the lowered demand response) for each of the consumer installation systems 300.

When the demand response requested by the external engine control device 910 is an increased demand response, the customer-specific power demand calculation unit 195 sets the total increased demand response request amount from the external engine control device 910 to each of the consumer installation systems 300. Assign to. As a result, the demanded electric energy calculation unit 195 for each consumer determines the required electric energy for each consumer (required amount for increased demand response) for each of the consumer installation systems 300.

Next, the first communication unit 110 of the host control device 100 sets the demand response start time, the consumer-specific baseline, and the consumer-specific electric energy required for the consumer-specific baseline in each customer installation system 300. It is transmitted to the lower control device 200 (sequence S322).
The upper control device 100 transmits the consumer-specific baseline and the consumer-specific electric energy required for the consumer-specific baseline to the lower control device 200, so that the lower control device 200 targets the demand response for each customer. It is possible to calculate the target value of the amount of power demand for each customer. As a result, the lower control device 200 adjusts the power supply and demand based on the demand power amount target value even when the power demand amount of the consumer installation system 300 during the demand response execution time fluctuates from the consumer-specific baseline. , The required demand response for each customer can be performed with higher accuracy.

Alternatively, the upper control device 100 may transmit the demand response start time and the demanded electric energy for each customer to the lower control device 200 without transmitting the baseline of the consumer installation system 300.
When the demand response requested by the external engine control device 910 is a lowered demand response, the host control device 100 determines the demand response start time, the baseline for each customer, and the chargeable / dischargeable device 311 calculated by the equation (3). The set value of the discharge power amount of the above may be transmitted to the lower control device 200 (in the equation (3), the operating state of the chargeable / discharging device 311 for purposes other than the demand response immediately before the demand response is discharged. Represents a case).

In addition, the upper control device 100 sends the lower control device 200 a value such as an average discharge power value × a frame length value and a value of the required power amount for each customer (here, a lower demand response amount with respect to the baseline for each customer). You may send it. Then, the lower control device 200 may calculate the discharge power amount setting value of the chargeable / dischargeable device 311 by using the value received from the upper control device 100.
Alternatively, when the storage capacity of the lower control device 200 is sufficiently large, the lower control device 200 stores the history data of the discharge power of the chargeable / dischargeable device 311, and the “average discharge power amount [W] of the equation (3)” is stored. ] × Frame length [h] ”, and the value may be used to calculate the discharge power amount setting value of the chargeable / dischargeable device 311.

When the demand response requested by the external engine control device 910 is an increased demand response, the host control device 100 determines the demand response start time, the baseline for each customer, and the chargeable / dischargeable device 311 calculated by the equation (4). The set value of the charge power amount of the above may be transmitted to the lower control device 200 (in the equation (4), the operating state of the chargeable / dischargeable device 311 for purposes other than the demand response immediately before the demand response is charging. Represents a case).

In this case as well, the upper control device 100 sends the lower control device 200 to the lower control device 200, such as the average charging power value × the frame length value, and the required power amount for each customer (here, the increased demand response amount with respect to the baseline for each customer). You may want to send the value. Then, the lower control device 200 may calculate the charge power amount setting value of the charge / discharge possible device 311 by using the value received from the upper control device 100.
Alternatively, when the storage capacity of the lower control device 200 is sufficiently large, the lower control device 200 stores the history data of the charging power of the chargeable / discharging device 311, and the "average charging power amount [W] of the equation (4)" is stored. ] × Frame length [h] ”, and the value may be used to calculate the charge power amount setting value of the chargeable / dischargeable device 311.

When the host controller 100 transmits the demand response start time, the consumer-specific baseline, and the consumer-specific electric energy in sequence S322, the consumer-specific target value acquisition unit 294 of the lower controller 200 sends the demand by consumer. The electric energy target value is calculated (sequence S331). The customer-specific target value acquisition unit 294 calculates the demand-specific electric energy target value by reflecting the demanded electric energy for each customer in the electric energy of the baseline for each customer.
After the sequence S331, the power system 1 ends the process of FIG.

Each of the customer installation systems 300 implements the demand response for each customer when the demand response start time arrives.
If the consumer installation system 300 implements the energy management service before the start of the demand response, the implementation of the energy management service is continued until the demand response start time. In this way, by predetermining whether or not the customer installation system 300 will continue to execute the service until the demand response start time, the customer-specific information acquisition unit 191 of the host control device 100 can perform the demand response start time. It is possible to predict the storage capacity and the free capacity of the chargeable / discharging device 311 in the above with higher accuracy.

While the demand response is being implemented (frame (i)), the host control device 100 can either stop the energy management service or continue the energy management service.
When the demand response for each customer is lowered and the demand response is lowered, the chargeable / discharging device 311 of the customer installation system 300 discharges to the power system 920 within a range that does not reverse power flow according to the control of the lower control device 200 and XEMS321. On the other hand, when the demand response for each customer is increased and the demand response is increased, the charge / discharge capable device 311 charges, so that the reverse power flow to the power system 920 does not occur.

Next, charging / discharging in the individual consumer installation system 300 will be described for each of the cases where the total demand response request is a lowered demand response and a raised demand response.
<State of the consumer installation system 300 in the case of lowered demand response>
In the case of lowered demand response, the target value of power demand by consumer is smaller than the baseline by consumer. The relationship between these values and the estimated value of power demand by consumer when demand response is not implemented is
(Case 1d) Predicted value of electric energy demand by consumer when demand response is not implemented ≤ Target value of electric energy demand by consumer (Case 2d) Target value of electric energy demand by consumer <Customer when demand response is not expected to be implemented Estimated value of electric energy by demand ≤ Baseline by consumer (Case 3d) Baseline by consumer <It can be classified into three cases: Estimated value of electric energy by consumer when demand response is not implemented.

<Implementation method 1 of lower demand response>
In the method 1 for implementing the lowered demand response, the target value of the electric energy demand for each customer is achieved as follows according to which of the above three cases corresponds to each of the customer installation systems 300.

(In case of case 1d)
The customer installation system 300 implements a raised demand response as a demand response for each customer.
In this case, the charge / discharge control unit 295 controls the charge / discharge possible device 311 to set the target value and the predicted value of the demand power amount for each consumer (the predicted value for the demand power amount for each customer when the demand response is not implemented). By charging the difference electric energy, the actual value of the electric energy demand for each customer is adjusted to the target value.

FIG. 11 is a diagram showing a first example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 11 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 11 shows an example of the power demand amount for each customer of one customer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 1d.
FIG. 11 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) used in the following description mean past frames, frame (i) means current frames (frames including the current time), and frames (i + 1) mean future frames.

Line L111 indicates a consumer-specific baseline from frame (i-2) to frame (i + 1).
Line L112 shows the actual value of the electric energy demanded by the consumer in each of the frames (i-2) and (i-1).
Line L113 indicates the target value of the electric energy demand for each consumer in the demand response for each consumer. The target value of the amount of power demand by consumer is a value that reflects the amount of demand in the demand response by consumer in the baseline by consumer.

Line L114 shows the latest forecast value of electric energy demand by consumer. The latest forecast value of power demand by consumer shown by line L114 corresponds to the forecast value of power demand by consumer when demand response is not implemented. In the example of FIG. 11, the predicted value of the power demand by consumer when the demand response is not implemented is equal to or less than the target value of power demand by customer.
The arrow B111 indicates the required amount in the demand response.
The arrow B112 indicates an increase / decrease target value of the electric power demand amount for each consumer.
By charging the electric power amount indicated by the arrow B112 by the chargeable / discharging device 311, the electric power demand amount for each consumer can be adjusted to the electric power demand amount target value for each consumer.

(In the case of case 2d)
The customer installation system 300 implements a lowered demand response as a demand response for each customer.
In this case, the charge / discharge control unit 295 controls the charge / discharge possible device 311 to set the target value and the predicted value of the demand power amount for each consumer (the predicted value for the power demand amount for each customer when the demand response is not implemented). By discharging the difference electric energy, the actual value of the electric energy demand for each customer is adjusted to the target value.

FIG. 12 is a diagram showing a second example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 12 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 12 shows an example of the power demand amount of one consumer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 2d.
FIG. 12 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.

Lines L111 to L113 and arrow B111 in FIG. 12 are the same as in the case of FIG. Further, the same as in the case of FIG. 11, the latest predicted power demand value indicated by the line L124 corresponds to the predicted power demand value for each consumer when the demand response is not executed.
In FIG. 12, the predicted electric energy demand value (line L124) for each consumer when the demand response is not implemented is larger than the target electric energy demand value for each consumer (line L113), and the baseline for each consumer (line L111). It differs from the case of FIG. 11 in that it is as follows. Along with this, the increase / decrease target value of the electric power demand by consumer indicated by the arrow B122 is the decrease of the electric energy.
When the chargeable / discharging device 311 discharges the electric power indicated by the arrow B122, the electric power demand amount for each consumer can be adjusted to the electric power demand amount target value for each consumer.

(In the case of case 3d)
The customer installation system 300 implements a lowered demand response as a demand response for each customer.
As in the case of Case 2d, the charge / discharge control unit 295 controls the charge / discharge possible device 311 to determine the target value and the predicted value of the power demand amount for each customer (the power demand amount forecast for each customer when the demand response is not implemented). By discharging the electric energy difference from the value), the actual value of the electric energy demanded by each consumer is adjusted to the target value.

FIG. 13 is a diagram showing a third example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 13 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 13 shows an example of the power demand amount for each customer of one customer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 3d.
FIG. 13 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.

Lines L111 to L113 and arrow B111 in FIG. 13 are the same as in the case of FIG. Further, the same as in the case of FIG. 11, the latest predicted value of the demand power amount for each consumer shown by the line L134 corresponds to the predicted value of the demand power amount for each customer when the demand response is not executed.
FIG. 13 is different from the case of FIG. 11 in that the predicted value of the demand power amount (line L134) for each consumer when the demand response is not implemented is larger than the baseline (line L111). Along with this, the increase / decrease target value of the electric power demand by consumer indicated by the arrow B132 is the decrease of the electric energy.
When the chargeable / discharging device 311 discharges the electric power indicated by the arrow B132, the electric power demand amount for each consumer can be adjusted to the electric power demand amount target value for each consumer.

However, the amount of power that can be discharged by the chargeable / dischargeable device 311 for lower demand response is limited to the amount of power that is equal to or less than the total dischargeable amount [Wh] described above. The total dischargeable amount is the smaller of the dischargeable amount based on the stored amount and the dischargeable amount based on the rating.
When the total dischargeable amount is insufficient with respect to the discharge power amount required for the lowered demand response, the insufficient power amount becomes an error of the implementation amount with respect to the required amount of the demand response.

In case 2d and case 3d in which the lowered demand response is performed, in general, the case 3d in which the predicted value of the electric energy demand by the consumer when the demand response is not implemented is larger than the baseline by the consumer is the lower demand response. It is considered that the amount of discharge power required for this is large. From this, in the consumer installation system 300 corresponding to the case 3d, there is a relatively high possibility that the total dischargeable amount is insufficient with respect to the discharge power amount required for the lowered demand response.

<Implementation method 2 for lower demand response>
In the lower demand response implementation method 2, the electric power system is charged and discharged as follows for each customer installation system 300 according to which of the above three cases is applicable. The target value of the amount of power demand is achieved for the entire customer installation system 300 of 1.

(In case of case 1d)
The customer installation system 300 does not implement demand response for each customer.
FIG. 14 is a diagram showing a fourth example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 14 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 14 shows an example of the power demand amount for each customer of one customer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 1d.

FIG. 14 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.
Lines L111, L112, L114 and arrow B111 in FIG. 14 are the same as in the case of FIG.
FIG. 14 is different from the case of FIG. 11 in that the demand power amount target value for each consumer is reset. The target value of the electric energy demand by consumer is reset from the electric energy indicated by the line L143 to the electric energy indicated by the line L114 (the predicted value of the electric energy demand by consumer when the latest demand response is not implemented). There is.

In the example of FIG. 14, since the target value of the power demand by consumer after resetting is set to the predicted power demand by consumer when the latest demand response is not implemented, the demanded power by consumer is set. Is 0.
Therefore, the charge / discharge capable device 311 is not charged to match the demand power amount for each consumer in the demand response for each customer with the demand power amount target value.

When the chargeable / discharging device 311 charges for increased demand response as in the consumer installation system 300 of case 1d in the above-described implementation method 1, AC / DC conversion during charging and discharge of charged power are performed. Loss occurs in each of DC / AC conversion. On the other hand, in the case of Case 1d in the Implementation Method 2, the chargeable / discharging device 311 of the consumer installation system 300 does not need to be charged for the increased demand response and discharged the charged electric energy. In this respect, the consumer installation system 300 can avoid power loss.

(In the case of case 2d)
Implement a lower demand response. In this case, the charge / discharge control unit 295 controls the charge / discharge possible device 311 as in the case of case 2d in the above-described implementation method 1, and sets the target value and the predicted value of the electric energy demand for each customer (assuming non-implementation of demand response). By discharging the amount of power that is different from the estimated value of power demand by consumer at that time, the actual value of power demand by consumer is adjusted to the target value.

(In the case of case 3d)
After the upper control device 100 resets the demand power target value for each customer, the consumer installation system 300 lowers the demand response as the demand response for each customer and executes the demand response.
In the second implementation method 2, the amount of power demanded by the entire consumer installation system 300 of the power system 1 is reduced by the amount that the chargeable / discharging device 311 of the consumer installation system 300 corresponding to case 1d is not charged. The upper control device 100 allocates the decrease in the power demand amount to the target value of the power demand amount for each customer of the consumer installation system 300 corresponding to the case 3d, so that the customer of the customer installation system 300 corresponding to the case 3d The other power demand target value is reset to a larger value (that is, the lower demand response amount can be reduced).

FIG. 15 is a diagram showing a fifth example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 15 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 15 shows an example of the power demand amount for each customer of one customer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 3d.
FIG. 15 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.

Lines L111, L112, L114 and arrow B111 in FIG. 15 are the same as in the case of FIG.
FIG. 15 is different from the case of FIG. 13 in that the target value of the amount of power demand for each consumer is reset. The electric energy demand target value for each consumer is reset from the electric energy indicated by the line L153 to the electric energy indicated by the line L155. As for the power demand target value for each customer after resetting shown by line L155, the customer installation system 300 corresponding to case 1d sets the power demand amount for each customer in the demand response to the power demand target value for each customer. The value is larger than the customer-specific electric energy target value before resetting, which is indicated by the line L153, depending on the fact that charging for matching is not performed. As a result, the increase / decrease target value of the electric power demand indicated by the arrow B152 is larger than the increase / decrease target value of the electric power demand before the resetting of the electric energy demand target value for each consumer indicated by the arrow B132 of FIG. The amount of decrease is small.

The consumer installation system 300 corresponding to case 3d performs a lower demand response based on the reset target value, so that the amount of power to be discharged by the chargeable / dischargeable device 311 becomes smaller than that before the reset. As a result, it is less likely that the total dischargeable amount will be insufficient for the discharge power amount required for the lowered demand response. According to the implementation method 2, in this respect, the error of the implementation amount with respect to the required amount of the demand response can be reduced.

Here, the case where both the customer installation system 300 corresponding to the case 1d and the customer installation system 300 corresponding to the case 3d are one is described as an example, but the customer installation system corresponding to the case 1d has been described. The same method can be applied to the case where there are at least a plurality of the customer installation system 300 corresponding to the case 3d and the 300. In this case as well, the charging of the consumer installation system 300 corresponding to case 1d is stopped, and the consumer installation corresponding to case 3d is installed according to the decrease in the power demand (total power demand) of the entire power system 1. The above-mentioned effect can be obtained by resetting the demand response target value (required electric energy for each consumer) of the system 300.

At this time, the demanded electric energy calculation unit 195 for each consumer of the upper control device 100 measures the decrease in the total demanded electric energy by the amount of electric power that each of the consumer-installed systems 300 corresponding to Case 3d can discharge by demand response. Allocate within the range. That is, the customer-specific electric energy calculation unit 195 requests the customer-specific electric energy of the customer-installed system 300 corresponding to case 3d so that the consumer-installed system 300 corresponding to case 3d does not become the situation of case 1d. To update.

As a method for determining how much the decrease in the total demand power amount is allocated to which customer installation system 300 among the customer installation systems 300 corresponding to Case 3d by the demand power amount calculation unit 195 for each customer. , Various methods can be used.
For example, the demanded electric energy calculation unit 195 for each consumer indicates that, among the consumer installed systems 300 corresponding to case 3d, the consumer installed system 300 in which the chargeable / discharging device 311 can discharge a small amount of electric energy for demand response is used. In order, the decrease in the total power demand may be allocated. As a result, it is possible to reduce the risk that the customer installation system 300 corresponding to case 3d cannot perform the demand response for each customer.

Alternatively, the demanded electric energy calculation unit 195 for each consumer may evenly allocate the decrease in the total demanded electric energy to all the consumer installation systems 300 corresponding to the case 3d. In this case, the load of the demanded electric energy calculation unit 195 for each consumer is light because the calculation performed by the demanded electric energy calculation unit 195 for each consumer is relatively simple, and the customer installation corresponding to case 3d It is possible to reduce the risk that the system 300 cannot perform the demand response.

Further, when the number of consumer installation systems 300 corresponding to case 1d is larger than the number of consumer installation systems 300 corresponding to case 3d, the total electric energy demanded only by the consumer installation system 300 corresponding to case 3d. If the decrease in the total electric energy cannot be absorbed, the customer-specific electric energy demand calculation unit 195 may allocate the decrease in the total electric energy to the customer installation system 300 corresponding to Case 2d. As a result, the demand response amount of the consumer installation system corresponding to case 2d can also be reduced.

<State of the consumer installation system 300 in the case of increased demand response>
In the case of increased demand response, the target value of power demand by consumer is larger than the baseline by consumer. The relationship between these values and the estimated value of power demand by consumer when demand response is not implemented is
(Case 1u) Predicted value of electric energy demand by consumer when demand response is not implemented ≧ Target value of electric energy demand by consumer (Case 2u) Target value of electric energy demand by consumer ＞ Consumers when demand response is not expected to be implemented Demanded electric energy forecast value ≧ Consumer-specific baseline (case 3u) Consumer-specific baseline ＞ It can be classified into three cases: demand demand electric energy forecast value by consumer when demand response is not implemented.

<Implementation method 1 for raised demand response>
In the method 1 of implementing the increased demand response, the target value of the electric energy demand for each customer is achieved as follows according to which of the above three cases corresponds to each of the customer installation systems 300.

(In case of case 1u)
The customer installation system 300 implements a lowered demand response as a demand response for each customer.
In this case, the charge / discharge control unit 295 controls the charge / discharge possible device 311 to set the target value and the predicted value of the demand power amount for each consumer (the predicted value for the power demand amount for each customer when the demand response is not implemented). By discharging the difference electric energy, the actual value of the electric energy demand for each consumer is adjusted to the target value.

FIG. 16 is a diagram showing a sixth example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 16 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 16 shows an example of the power demand amount of one consumer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 1u.
FIG. 16 shows an example in the case where the demand response is being executed. Here, too, the frames (i-2) and (i-1) mean past frames, the frame (i) means the current frame (frame including the current time), and the frame (i + 1) means the future frame.

Line L211 shows a consumer-specific baseline from frame (i-2) to frame (i + 1).
Line L212 shows the actual value of the electric energy demanded by the consumer in each of the frames (i-2) and (i-1).
Line L213 shows the electric energy target value for each consumer in the demand response.

Line L214 shows the latest forecast value of electric energy demand by consumer. The latest forecast value of power demand by consumer shown by line L214 corresponds to the forecast value of power demand by consumer when demand response is not implemented. In the example of FIG. 16, the predicted value of the power demand by consumer when the demand response is not implemented is equal to or larger than the target value of power demand by consumer.
Arrow B211 indicates a required amount in demand response.
Arrow B212 indicates an increase / decrease target value of electric power demand by consumer.
When the chargeable / discharging device 311 discharges the electric power indicated by the arrow B212, the electric power demand amount for each consumer can be adjusted to the electric power demand amount target value for each consumer.

(In case of case 2u)
The customer installation system 300 implements a raised demand response as a demand response for each customer.
In this case, the charge / discharge control unit 295 controls the charge / discharge possible device 311 to set the target value and the predicted value of the demand power amount for each consumer (the predicted value for the demand power amount for each customer when the demand response is not implemented). By charging the difference electric energy, the actual value of the electric energy demand for each customer is adjusted to the target value.

FIG. 17 is a diagram showing a seventh example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 17 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 17 shows an example of the power demand amount for each customer of one customer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 2u.
FIG. 17 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.

Lines L211 to L213 and arrow B211 in FIG. 17 are the same as in the case of FIG. Further, in the case of FIG. 16, the latest predicted value of the demand power amount for each consumer when the demand response is not implemented corresponds to the latest predicted value of the demand power amount for each customer when the demand response is not implemented. Is similar to.
In FIG. 17, the predicted electric energy demand value for each consumer (line L224) when the demand response is not implemented is smaller than the target electric energy demand value for each consumer (line L213), and the baseline for each consumer (line L211). The above points are different from the case of FIG. Along with this, the target value for increase / decrease in the amount of electric power demand by consumer indicated by arrow B222 is an increase in the amount of electric power.
By charging the electric power amount indicated by the arrow B122 by the chargeable / discharging device 311, the electric power demand amount for each consumer can be adjusted to the electric power demand amount target value for each consumer.

(In case of case 3u)
The customer installation system 300 implements a raised demand response as a demand response for each customer.
As in the case of Case 2d, the charge / discharge control unit 295 controls the charge / discharge possible device 311 to determine the target value and the predicted value of the power demand amount for each customer (the power demand amount forecast for each customer when the demand response is not implemented). By charging the electric energy that is different from the value), the actual value of the electric energy demand for each customer is adjusted to the target value.

FIG. 18 is a diagram showing an eighth example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 18 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 18 shows an example of the electric energy demanded by each consumer of one consumer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 3u.
FIG. 18 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.

Lines L211 to L213 and arrow B211 in FIG. 18 are the same as in FIG. Further, in the case of FIG. 16, the latest predicted value of the demand power amount for each consumer when the demand response is not implemented corresponds to the latest predicted value of the demand power amount for each customer when the demand response is not implemented. Is similar to.
FIG. 18 is different from the case of FIG. 16 in that the predicted value of the demand power amount for each customer (line L234) when the demand response is not implemented is smaller than the baseline for each customer (line L211). Along with this, the target value for increase / decrease in the amount of electric power demand by consumer indicated by arrow B232 is an increase in the amount of electric power.
By charging the electric power amount indicated by the arrow B232 by the chargeable / discharging device 311, the electric power demand amount for each consumer can be adjusted to the electric power demand amount target value for each consumer.

However, the amount of power that can be charged by the chargeable / dischargeable device 311 for the increased demand response is limited to the amount of power that is equal to or less than the total chargeable amount [Wh] described above. The total rechargeable amount is the smaller of the rechargeable amount based on the stored amount and the rechargeable amount based on the rating.
When the total chargeable amount is insufficient with respect to the charge power amount required for the increased demand response, the insufficient power amount becomes an error of the implementation amount with respect to the required amount of the demand response.

In case 2u and case 3u where the increased demand response is performed, in general, the case 3u in which the predicted value of the electric energy demand by the customer when the demand response is not implemented is smaller than the baseline by the customer is the increased demand response. It is considered that the amount of charging power required for this is large. From this, in the consumer installation system 300 corresponding to the case 3u, there is a relatively high possibility that the total chargeable amount is insufficient with respect to the charge power amount required for the increased demand response.

<Implementation method 2 for raised demand response>
In the method 2 for implementing the increased demand response, the electric power system is charged and discharged as follows for each customer installation system 300 according to which of the above three cases is applicable. The target value of the amount of power demand is achieved for the entire customer installation system 300 of 1.

(In case of case 1u)
The customer installation system 300 does not implement demand response for each customer.
FIG. 19 is a diagram showing a ninth example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 19 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 19 shows an example of the power demand amount for each customer of one customer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 1u.

FIG. 19 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.
Lines L211, L212, L214 and arrow B211 in FIG. 19 are the same as in FIG.
FIG. 19 is different from the case of FIG. 16 in that the target value of the demand power amount for each consumer is reset. The target value of the electric energy demand by consumer is reset from the electric energy indicated by the line L243 to the electric energy indicated by the line L214 (the predicted value of the electric energy demand by consumer when the latest demand response is not implemented). There is.

In the example of FIG. 19, since the target value of the power demand by consumer after resetting is set to the predicted power demand by consumer when the latest demand response is not implemented, the demanded power by consumer is set. Is 0.
Therefore, the charge / discharge possible device 311 does not discharge in order to match the demand power amount for each consumer in the demand response with the demand power amount target value for each customer.

When the chargeable / discharging device 311 discharges for lower demand response as in the consumer installation system 300 of case 1u in the above-described implementation method 1, DC / AC conversion at the time of discharging and charging of the discharged power are performed. Loss occurs in each of AC / DC conversion. On the other hand, in the case of Case 1u in the Implementation Method 2, the chargeable / discharging device 311 of the consumer installation system 300 does not need to discharge for the lowered demand response and charge the discharged electric energy. In this respect, the consumer installation system 300 can avoid power loss.

(In case of case 2u)
The customer installation system 300 implements a raised demand response as a demand response for each customer. In this case, the charge / discharge control unit 295 controls the charge / discharge possible device 311 as in the case of case 2u in the above-described implementation method 1, and the target value and the predicted value of the power demand amount for each customer (demand response non-execution assumption). By charging the amount of power that is different from the estimated value of power demand by customer at that time, the actual value of power demand by customer is adjusted to the target value.

(In case of case 3u)
After the host control device 100 resets the demand power target value, the consumer installation system 300 raises the demand response as a demand response for each customer and implements the demand response.
In the second implementation method 2, the amount of power demanded by the entire consumer installation system 300 of the power system 1 increases by the amount that the chargeable / discharging device 311 of the consumer installation system 300 corresponding to case 1u does not discharge. The upper control device 100 allocates the increase in the electric energy demand to the target value of the electric energy demand for each consumer of the consumer installation system 300 corresponding to the case 3u, so that the consumer of the consumer installation system 300 corresponding to the case 3u The other power demand target value is reset to a smaller value (that is, the increased demand response amount can be reduced).

FIG. 20 is a diagram showing a tenth example of an increase / decrease target of the electric energy demand for each consumer in the demand response. The horizontal axis of the graph of FIG. 20 indicates the time, and the vertical axis indicates the amount of electric power.
FIG. 20 shows an example of the power demand amount for each customer of one customer installation system 300 in each frame from 1 hour before to 1 hour after the demand response start time in the case of case 3u.
FIG. 20 shows an example in the case where the demand response is being executed. The frames (i-2) and (i-1) are past frames, the frame (i) is the current frame (frame including the current time), and the frame (i + 1) is the future frame.

Lines L211, L212, L214 and arrow B211 in FIG. 20 are the same as in FIG.
FIG. 20 is different from the case of FIG. 18 in that the target value of the amount of power demand for each consumer is reset. The electric energy demand target value for each consumer is reset from the electric energy indicated by the line L253 to the electric energy indicated by the line L255. As for the target value of the power demand by consumer after the resetting shown by the line L255, the customer installation system 300 corresponding to Case 1u sets the power demand by consumer in the demand response to the target value of power demand by customer. The value is smaller than the customer-specific electric energy target value before resetting, which is indicated by the line L253, depending on the fact that the discharge for matching is not performed. As a result, the increase / decrease target value of the electric energy indicated by the arrow B252 is smaller than the increase / decrease target value before the resetting of the electric energy demand target value for each customer indicated by the arrow B232 in FIG. It has become.

The consumer installation system 300 corresponding to case 3u performs an increased demand response based on the reset target value, so that the amount of power to be charged by the chargeable / dischargeable device 311 becomes smaller than that before the reset. As a result, it is less likely that the total chargeable amount will be insufficient for the charge power amount required for the increased demand response. According to the implementation method 2, in this respect, the error of the implementation amount with respect to the required amount of the demand response can be reduced.

Here, the case where both the consumer installation system 300 corresponding to the case 1u and the consumer installation system 300 corresponding to the case 3u are one is described as an example, but the consumer installation system corresponding to the case 1u has been described as an example. The same method can be applied to the case where there are at least a plurality of the customer installation system 300 corresponding to the case 3u and the 300. In this case as well, the discharge of the consumer installation system 300 corresponding to case 1u is stopped, and the consumer installation corresponding to case 3u is installed according to the increase in the power demand (total power demand) of the entire power system 1. The above-mentioned effect can be obtained by resetting the demand response target value (required electric energy for each consumer) of the system 300.

At this time, the customer-specific power demand calculation unit 195 of the host control device 100 charges the increase in the total power demand amount by the demand response of each of the customer installation systems 300 corresponding to case 3u. Allocate within the range. That is, the customer-specific electric energy calculation unit 195 requests the customer-specific electric energy of the consumer-installed system 300 corresponding to case 3u so that the consumer-installed system 300 corresponding to case 3u does not become the situation of case 1u. To update.

As a method for determining how much the increase in the total demand power amount is allocated to which customer installation system 300 among the customer installation systems 300 corresponding to Case 3u by the demand power amount calculation unit 195 for each customer. , Various methods can be used.
For example, the demanded electric energy calculation unit 195 for each consumer indicates that among the consumer installed systems 300 corresponding to case 3u, the consumer installed system 300 in which the chargeable / discharging device 311 can be charged for demand response is small. In order, the increase in the total power demand may be allocated. As a result, it is possible to reduce the risk that the customer installation system 300 corresponding to case 3u cannot perform the demand response for each customer.

Alternatively, the demanded electric energy calculation unit 195 for each consumer may evenly allocate the increase in the total demanded electric energy to all the consumer installation systems 300 corresponding to Case 3u. In this case, the load of the demanded electric energy calculation unit 195 for each consumer is light because the calculation performed by the demanded electric energy calculation unit 195 for each consumer is relatively simple, and the customer installation corresponding to case 3u It is possible to reduce the risk that the system 300 cannot perform the demand response.

Further, when the number of the consumer installation systems 300 corresponding to the case 1u is larger than the number of the consumer installation systems 300 corresponding to the case 3u, the total electric energy demanded by the consumer installation system 300 corresponding to the case 3u alone. If the increase in the total electric energy cannot be absorbed, the demand electric energy calculation unit 195 for each consumer may allocate the increase in the total electric energy to the customer installation system 300 corresponding to Case 2u. As a result, the demand response amount of the consumer installation system corresponding to case 2u can also be reduced.

FIG. 21 is a diagram showing an example of a processing procedure in which the power system 1 resets the charge / discharge power target value of each charge / discharge possible device 311. The electric power system 1 performs the process of FIG. 21 after the gate is closed, for example, when a demand response is executed.
The sequences S411 to S421 in FIG. 21 are the same as the sequences S111 to S121 in FIG. 7.

After the sequence S421, in the host control device 100, the customer-specific information acquisition unit 191 calculates the demand power amount forecast value for each customer (the demand power amount forecast value for each customer when the demand response is not implemented) (sequence). S431). The customer-specific information acquisition unit 191 calculates the demand power consumption forecast value for each customer when the demand response is not executed, for example, by the same method as the method for calculating the consumer-specific baseline in the sequence S131 of FIG. .. Since the baseline value cannot be changed, the power system 1 sets the predicted power demand value for each consumer calculated in sequence S431 when the demand response is not implemented as a value different from the baseline for each consumer. deal.

Next, the demanded electric energy calculation unit 195 for each consumer determines the consumer installation system 300 to be stopped charging / discharging for the demand response (sequence S432). When the total demand response is lowered and the demand response is obtained, the customer-specific power demand calculation unit 195 demands that the customer installation system 300 corresponding to the above-mentioned case 1d be stopped from being charged for the customer-specific demand response. Decide on a house installation system 300. When the total demand response is increased and the demand response is increased, the customer-specific power demand calculation unit 195 demands that the consumer installation system 300 corresponding to the above-mentioned case 1u be stopped from being discharged for the consumer-specific demand response. Decide on a house installation system 300.

In addition, the demanded electric energy calculation unit 195 for each consumer calculates the total value of the required electric energy for the charge / discharge stop (sequence S433). When the total demand response is lowered and the demand response is obtained, the demanded electric energy calculation unit 195 for each consumer calculates the total value of the decrease in the electric energy required due to the suspension of charging for the demand response for each consumer. When the total demand response is increased and the demand response is increased, the demanded electric energy calculation unit 195 for each consumer calculates the total value of the increase in the electric energy required due to the discontinuation of the discharge for the demand response for each consumer.

Next, the demanded electric energy calculation unit 195 for each consumer allocates the total value of the demanded electric energy for the charge / discharge stop to the consumer installation system 300, and recalculates the required electric energy for each consumer (sequence S434). ..
When the total demand response is lowered, the demand response calculation unit 195 for each consumer requests the total value of the decrease in the demand power due to the suspension of charging for the demand response for each customer (the decrease in the total consumer energy). Is assigned to the consumer installation system 300 corresponding to the above-mentioned case 3d, and the required electric energy for each consumer is recalculated. If the decrease in the total electric energy cannot be allocated only by the consumer installation system 300 corresponding to the case 3d, the customer-specific electric energy calculation unit 195 also applies the total to the consumer installation system 300 corresponding to the case 2d. The decrease in the amount of power demand may be allocated.

When the total demand response is increased and the demand response is obtained, the demand power calculation unit 195 for each consumer is the total value of the increase in the demand power due to the discontinuation of the discharge for the demand response for each customer (the increase in the total consumer energy). Is assigned to the consumer installation system 300 corresponding to the above-mentioned case 3u, and the required electric energy for each consumer is recalculated. If the increase in the total power demand cannot be allocated only by the consumer installation system 300 corresponding to the case 3u, the demand power calculation unit 195 for each customer also totals the customer installation system 300 corresponding to the case 2u. The increase in the amount of power demand may be allocated.

Then, the demanded electric energy calculation unit 195 for each consumer transmits the recalculated required electric energy for each consumer to the lower control device 200 via the first communication unit 110 (sequence S435).
In the lower control device 200, the customer-specific target value acquisition unit 294 recalculates the customer-specific target electric energy (sequence S441). The customer-specific target value acquisition unit 294 recalculates the customer-specific target power amount in the same manner as the method for calculating the consumer-specific target power amount in the sequence S331 of FIG.
After the sequence S441, the power system 1 ends the process of FIG.
It is preferable that the electric power system 1 repeats the process of FIG. 21, for example, every minute. This is expected to improve the accuracy of demand response implementation. Further, it is expected that the higher the frequency with which the electric power system 1 repeats the process of FIG. 21, the higher the frequency of grasping each state of the consumer installation system 300, and the higher the accuracy of demand response execution.

Next, a method in which the lower control device 200 controls the charge / discharge of the charge / discharge possible device 311 will be described.
<Charging / discharging control method when there is a peak shift mode>
In the consumer-installed system 300, which has a peak shift mode in the control logic of the lower control device 200 as a power conditioning system, the target power in the peak shift mode may reflect the charge / discharge portion for demand response. As a result, charging / discharging for demand response can be performed in real time by using the charge / discharge control function for peak shift.

As the target power in the peak shift mode, the target value of the demand power [W] of the consumer installation system 300 at the interconnection point between the consumer installation system 300 and the power system 920 (= demand power [W] for each customer) is set. Set. Normally, when control for demand response is not performed in the peak shift mode, this target value is set to approximately 0 during the discharge time zone when the electricity charge is high, and the lower control device 200 as the power conditioning system has this target value. The discharge of the chargeable / dischargeable device 311 is controlled in real time according to the target value. On the other hand, during the charging time period when the electricity charge is low, the target value of the required power [W] is not used for controlling the charging / discharging of the charge / dischargeable device 311, and the charge / dischargeable device 311 alone is used as the charging power. The maximum charge power is set (for example, to the rated value of the charge power). The lower control device 200 as a power conditioning system controls the charging of the chargeable / discharging device 311 with this charge upper limit power.

On the other hand, when controlling for demand response by utilizing the peak shift mode, for example, when lowering the demand response to the discharge time zone where the electricity charge is high, the discharge time zone where the electricity charge is high is expected in advance. The target value of the demand power [W] of is set to a value larger than 0. As a result, the demand power remains during the demand response execution time, and the lowered demand response can be executed.

In addition, if demand response is expected in the charging time zone when the electricity charge is low, set the charging power (target value) in the charging time zone where the electricity charge is low to a value smaller than the upper limit charging power in advance. .. For example, if the amount of electric power required to fully charge the chargeable / dischargeable device 311 is Q [Wh], and if there is T [h] in the time zone during which charging is possible and the electricity rate is low, the Q / T With [W] as the upper limit power for charging, it is set to charge with this upper limit power for charging (or at a predetermined value equal to or more than this upper limit for charging power and less than or equal to the rated charging power).

In addition, when the demand response is performed by lowering the electricity charge during the charging time zone, it is conceivable that the chargeable / discharging device 311 is originally charging. In this case, the lower control device 200 can be used for demand response by not only discharging the chargeable / discharging device 311 but also reducing the amount of charging power or stopping charging. The lower control device 200 achieves the target value of the demand power amount for each consumer, which is the target value of the lower demand response, by utilizing the reduction of the charge power amount of the chargeable / dischargeable device 311 or the stop of charging, and further the discharge. Controls the chargeable / dischargeable device 311.

Similarly, when the demand response is performed by raising the electricity charge during the discharge time zone, it is conceivable that the charge / discharge capable device 311 originally discharges. In this case, the lower control device 200 can be used not only for charging the chargeable / dischargeable device 311 but also for reducing the amount of discharge power or stopping the discharge for demand response. The lower control device 200 achieves the target value of the demand power amount for each consumer, which is the target value of the increased demand response, by utilizing the reduction of the discharge power amount of the chargeable / dischargeable device 311 or the stop of the discharge, and further the charging. Controls the chargeable / dischargeable device 311.

<Discharge control method when there is a peak shift mode>
In the consumer installation system 300, which has a peak shift mode in the control logic of the lower control device 200 as the power conditioning system, the target power in the peak shift mode may be lowered to reflect the discharge amount for the demand response.
In this case, the target value in the peak shift mode is set to the discharge power target value [W] in the peak shift mode calculated by the equation (5).

In this case, the target value of the power demand by consumer is higher than the power demand by consumer when the charge / discharge device 311 is charging / discharging in the peak shift mode when the demand response is not performed. Applicable when is small.

Based on the equation (5), the lower control device 200 can cause the charge / discharge possible device 311 to perform discharge for lower demand response by controlling in the peak shift mode.
When the upper control device 100 updates the electric energy demand target value for each customer during the execution of the demand response, the lower control device 200 sets the updated electric energy demand target value for each customer and the remaining frame time (remaining demand response). Time) is used to recalculate the discharge power target value [W] in the peak shift mode of the equation (5), and reset it to the target value of the peak shift mode.

<Discharge control method when there is no peak shift mode>
In the consumer installation system 300 in which the control logic of the lower control device 200 as a power conditioning system does not have a peak shift mode, the lower control device 200 integrates from the frame (i) start time at the interconnection point with the power system 920. Compare the electric energy with the electric energy demand target value for each consumer.

In this case, the cycle in which the lower control device 200 repeats the comparison between the integrated electric energy and the demand electric energy target value for each consumer is not limited to a specific cycle. For example, the lower control device 200 may compare the integrated electric energy amount with the demand electric energy target value for each consumer every minute, but the present invention is not limited to this.
The lower control device 200 receives the integrated electric energy at the interconnection point between the consumer installation system 300 and the power system 920 from, for example, the smart meter 930.

In this case, the lower control device 200 causes the chargeable / dischargeable device 311 to discharge the power obtained by dividing the insufficient power amount by the remaining time of the frame (i) as the discharge power target value as in the equation (6). It may be.

The remaining frame length [h] indicates the remaining time of the demand response (the time from the current time to the end time of the frame (i)).
As a result, the lower control device 200 performs high-precision feedback control in real time by using the charge / discharge of the charge / discharge possible device 311 within the range monitored and controlled by the lower control device 200 without communicating with the upper control device 100. It can be carried out. Therefore, the lower control device 200 can improve the accuracy of demand response execution in a state of being highly resistant to communication delays and failures, and in this respect, highly reliable demand response can be expected.

Alternatively, the lower control device 200 may use the rated discharge power of the charge / dischargeable device 311 as the discharge upper limit power, and cause the charge / discharge device 311 to discharge with a discharge power equal to or less than the discharge upper limit power. In this case, the responsiveness of the feedback in the demand response can be improved in that the chargeable / discharging device 311 can discharge more electric power.

<Charge control method when there is a peak shift mode>
In the consumer installation system 300, which has a peak shift mode in the control logic of the lower control device 200 as the power conditioning system, the target power in the peak shift mode may be increased to reflect the charge amount for the demand response.

In this case, the target value in the peak shift mode is set to the charging power target value [W] in the peak shift mode calculated by the equation (7).

In this case, the target value of the power demand by consumer is higher than the power demand by consumer when the charge / discharge device 311 is charging / discharging in the peak shift mode when the demand response is not performed. Applicable when is large.

Based on the equation (7), the lower control device 200 can raise the chargeable / dischargeable device 311 to charge for demand response by controlling in the peak shift mode.
When the upper control device 100 updates the electric energy demand target value for each customer during the execution of the demand response, the lower control device 200 uses the updated electric energy demand target value for each customer and the remaining frame time. The discharge power target value [W] in the peak shift mode of the equation (7) is recalculated and reset to the target value in the peak shift mode.

<Charge control method when there is no peak shift mode>
In the consumer installation system 300 in which the control logic of the lower control device 200 as a power conditioning system does not have a peak shift mode, the lower control device 200 is a coma (i) at the interconnection point between the consumer installation system 300 and the power system 920. ) Compare the integrated power consumption from the start time with the power demand target value for each customer.

In this case, the cycle in which the lower control device 200 repeats the comparison between the integrated electric energy and the demand electric energy target value for each consumer is not limited to a specific cycle. For example, the lower control device 200 may compare the integrated electric energy amount with the demand electric energy target value for each consumer every minute, but the present invention is not limited to this.
The lower control device 200 receives the integrated electric energy at the interconnection point between the consumer installation system 300 and the power system 920 from, for example, the smart meter 930.

In this case, the lower control device 200 causes the chargeable / dischargeable device 311 to be charged with the power obtained by dividing the insufficient power amount by the remaining time of the frame (i) as the charging power target value as in the equation (8). It may be.

As a result, the lower control device 200 performs high-precision feedback control in real time by using the charge / discharge of the charge / discharge possible device 311 within the range monitored and controlled by the lower control device 200 without communicating with the upper control device 100. It can be carried out. Therefore, the lower control device 200 can improve the accuracy of demand response execution in a state of being highly resistant to communication delays and failures, and in this respect, highly reliable demand response can be expected.

Alternatively, the lower control device 200 may use the rated discharge power of the charge / dischargeable device 311 as the charge upper limit power, and cause the charge / discharge device 311 to be charged with the charge power equal to or less than the charge upper limit power. In this case, the responsiveness of the feedback in the demand response can be enhanced in that the chargeable / discharging device 311 can charge more electric power.

When the consumer installation system 300 performs a peak shift, the host control device 100 collects the time zone power charge information and uses it for predicting the charge / discharge of the charge / discharge possible device 311 of the consumer installation system 300. May be good. For example, the host control device 100 predicts that the chargeable / discharging device 311 will discharge during a time when the electricity charge is high. Further, the host control device 100 predicts that the chargeable / discharging device 311 will be charged during the time when the electricity charge is low.

Further, when the consumer installation system 300 performs the peak shift and the demand response at the same time, the upper control device 100 sets the charge upper limit power and the discharge upper limit power for the peak shift, or one of them. You may. As a result, even when the consumer installation system 300 is charging / discharging for peak shift, it is possible to leave a surplus of charge / discharge power for demand response.

FIG. 22 is a diagram showing an example of the spare capacity for demand response when the consumer installation system 300 performs peak shift and demand response at the same time. The horizontal axis of the graph in FIG. 22 indicates the time. The vertical axis shows electric power. FIG. 22 shows an example in which the chargeable / discharging device 311 discharges due to a peak shift.
In the example of FIG. 22, the upper limit value of the discharge power of the chargeable / discharging device 311 for peak shift is set. The charge / discharge possible device 311 can use the power difference obtained by subtracting the upper limit value of the discharge power for peak shift from the rated discharge power as the discharge power for the demand response for each customer.

Line L311 shows an example of the power demand of the consumer installation system 300. The area of the region A11 indicates the amount of peak shift discharge power for one frame. The area of the area A12 indicates the discharge power for one frame in the demand response.
When the chargeable / discharging device 311 is discharging due to the peak shift, the decrease in the discharge power from the upper limit of the discharge power in the peak shift is used as the increase in the demand power in the demand response for each customer. Can be done.

Even when the charge / discharge device 311 charges for peak shift, by setting the upper limit of the charge power of the charge / discharge device 311 for peak shift, the charge / discharge device 311 can be charged for peak shift. It is possible to perform charging for charging and charging for demand response for each customer at the same time.
When the chargeable / discharging device 311 is charging for peak shift, the decrease in charge power from the upper limit of charge power in peak shift should be used as the decrease in demand power in the demand response for each customer. Can be done.

As described above, the consumer-specific baseline calculation unit 193 calculates the consumer-specific baseline, which is the allocation of the demand response baseline to each of the consumer installation systems 300. The demanded electric energy calculation unit 195 for each consumer calculates the required electric energy for each consumer, which is the allocation of the required electric energy in the demand response to each of the consumer installation systems 300. Further, the customer-specific electric energy calculation unit 195 assumes that the charge / discharge possible device 311 of the customer installation system 300 does not charge / discharge for the demand response, and the customer concerned at the demand response execution time. The predicted electric energy demand value of the installed system 300, which is the predicted electric energy demand value based on the state of the customer installed system 300 at a time after the calculation of the baseline, and the predicted electric energy demand value of the customer installed system 300 for each customer. Recalculate the required electric energy for each consumer based on the relationship with the target electric energy for each consumer, which reflects the required electric energy for each consumer in the baseline.

The demanded electric energy calculation unit 195 for each consumer recalculates the required electric energy for each consumer as described above, so that the error of the baseline for each consumer can be compensated for by the chargeable / discharging device 311. According to the host control device 100, in this respect, it is possible to reduce the error in the actual demand response with respect to the demand response request.

In addition, in the lowered demand response that reduces the demand power amount, the demand power amount calculation unit 195 for each customer sets the demand power amount prediction value (the demand power amount prediction value for each customer when the demand response is not implemented) for each customer. Demand power amount forecast value (customer when demand response non-implementation is assumed) in the increased demand response that increases the demand power amount by setting the demand power amount for each customer to 0 for the customer installation system 300 that is smaller than the demand power amount target value. The electric energy requirement for each consumer is set to 0 for the consumer installation system 300 in which the electric energy demand for another is larger than the target electric energy for each consumer.

By setting the required electric energy for each consumer to 0, the consumer installation system 300 is stopped from charging / discharging for demand response, and other consumers are installed by the amount of decrease in the charging electric energy or the discharging electric energy due to this cancellation. By reducing the amount of discharge power or the amount of charge power of the system 300, it is possible to reduce the loss during charging / discharging of the power system 1 as a whole without changing the total demand power amount.

Further, in the lower demand response, the demand power calculation unit 195 for each customer sets the predicted power demand value (the predicted power demand value for each consumer when the demand response is not implemented) from the target power demand value for each customer. According to the decrease in the electric energy demand by setting the electric energy demand for each consumer to 0 for the small consumer installation system 300, the electric energy demand forecast value (the electric energy demand forecast value for each consumer when the demand response is not implemented is assumed). ) Is larger than the target value of the electric energy demanded by the consumer. Expected electric energy demand value) is larger than the target electric energy demand value for each consumer. (Predicted value of electric energy demanded by consumer when demand response is not implemented) is smaller than the target value of electric energy demanded by consumer Reduce the electric energy required by consumer for the consumer installation system 300.

By setting the required electric energy for each consumer to 0, the consumer installation system 300 is stopped from charging / discharging for demand response, and other consumers are installed by the amount of decrease in the charging electric energy or the discharging electric energy due to this cancellation. By reducing the amount of discharge power or the amount of charge power of the system 300, it is possible to reduce the loss during charging / discharging of the power system 1 as a whole without changing the total demand power amount.

Further, in the lower demand response, the demand power calculation unit 195 for each customer sets the predicted power demand value (the predicted power demand value for each consumer when the demand response is not implemented) from the target power demand value for each customer. According to the decrease in the electric energy demand by setting the electric energy demand for each consumer to 0 for the small consumer installation system 300, the electric energy demand forecast value (the electric energy demand forecast value for each consumer when the demand response is not implemented is assumed). ) Is larger than the baseline for each customer The amount of power required for each customer for the customer installation system 300 is reduced, and in the increased demand response, the predicted value of the amount of power demand (the amount of power demand for each customer when the demand response is not implemented) Predicted electric energy (forecast value) is larger than the target electric energy demand for each consumer The predicted electric energy demand (demand response) according to the increase in the electric energy demand for the customer installation system 300 by setting the electric energy required for each consumer to 0. The estimated value of electric energy demanded by consumer at the time of non-implementation) is smaller than the baseline by consumer. The electric energy required by consumer for the consumer installation system 300 is reduced.

In the lowered demand response, in the consumer installation system 300 in which the predicted power demand value (the predicted power demand value for each consumer when the demand response is not implemented) is smaller than the baseline for each customer, the chargeable / dischargeable device 311 is used. It is considered that the amount of power to be charged is relatively large. On the other hand, by resetting the required power amount for each consumer, the amount of power to be charged by the chargeable / discharging device 311 becomes smaller than that before the reset. As a result, it is less likely that the chargeable amount of the chargeable / dischargeable device 311 is insufficient with respect to the charge power amount required for the demand response. According to the host control device 100, in this respect, it is possible to reduce the error in the execution amount with respect to the required amount of the demand response, and it is possible to carry out a highly reliable demand response.

Similarly, in the increased demand response, the consumer installation system 300 in which the predicted power demand value (the predicted power demand value for each consumer when the demand response is not implemented) is larger than the baseline for each customer can be charged and discharged. It is considered that the amount of electric power to be discharged by the device 311 is relatively large. On the other hand, by resetting the required power amount for each consumer, the amount of power to be discharged by the chargeable / dischargeable device 311 becomes smaller than that before the reset. As a result, the possibility that the dischargeable amount of the chargeable / dischargeable device 311 is insufficient with respect to the discharge power amount required for the demand response is reduced. According to the host control device 100, in this respect, it is possible to reduce the error in the execution amount with respect to the required amount of the demand response, and it is possible to carry out a highly reliable demand response.

In addition, the consumer-specific baseline calculation unit 193 uses the forecast information of the charge / discharge state of the chargeable / dischargeable device in the peak shift based on the information of the electric energy charge for each time zone, and uses the demand power of the consumer installation system 300. Predict the amount (for example, the predicted value of the amount of power demand for each customer when the demand response is not implemented).
As a result, it is expected that the consumer-specific baseline calculation unit 193 can predict the amount of power demand of the consumer installation system 300 with relatively high accuracy.

In addition, the second communication unit 210 includes the required power amount for each customer, which is the allocation of the required power amount in the demand response to the consumer installation system 300, and the allocation amount for the demand response baseline to the consumer installation system 300. Get a consumer-specific baseline and. The customer-specific target value acquisition unit 294 calculates the customer-specific power demand target value in which the customer-specific power demand amount is reflected in the power amount of the consumer-specific baseline. The charge / discharge control unit 295 controls the charge / discharge of the charge / discharge possible device so that the demand power amount of the consumer installation system 300 at the execution time of the demand response becomes the demand power amount target value for each customer.

In this way, the consumer installation system 300 controls the charge / discharge of the charge / discharge possible device 311 based on the demand power amount target value for each customer, so that the demand power amount forecast value for each customer when the demand response is not implemented is assumed. Even if is changed from the baseline, the change does not become an actual error with respect to the demand response request. According to the lower control device 200, in this respect, it is possible to reduce the error in the actual demand response with respect to the demand response request.

Further, in the charge / discharge control unit 295, the total demand response is lowered and the demand response is obtained, and the electric energy demand predicted value of the consumer installation system 300 at the execution time of the demand response (demand by consumer when the demand response is not implemented is assumed). When the electric energy forecast value) is smaller than the electric energy demand target value for each consumer, the amount of electric energy required for the consumer installation system 300 during the demand response implementation time is set as the electric energy demand target value for each consumer. The charge control of the dischargeable device 311 is stopped.
By reducing the amount of discharge power of the other consumer installation system 300 by the amount of decrease in the amount of charge power due to this cancellation, the loss during charging and discharging of the entire power system 1 can be reduced without changing the total amount of power demand. It can be reduced.

Further, in the charge / discharge control unit 295, the total demand response is lowered and the demand response is obtained, and the electric energy demand predicted value of the consumer installation system 300 at the execution time of the demand response (demand by consumer when the demand response is not implemented is assumed). When the electric energy forecast value) is larger than the electric energy demand target value for each consumer, it is based on the electric energy demand target value for each consumer reset in response to the cancellation of charge / discharge control by the other lower control device 200. , Controls the charge / discharge of chargeable / dischargeable equipment.

In the consumer installation system 300 in which the predicted power demand value (the predicted power demand value for each consumer when the demand response is not implemented) is larger than the baseline for each customer, the power amount to be discharged by the chargeable / discharging device 311. Is considered to be relatively large. On the other hand, by resetting the target value of the demand power amount for each consumer, the power amount to be discharged by the chargeable / dischargeable device 311 becomes smaller than that before the reset. As a result, it is less likely that the actual dischargeable amount is insufficient with respect to the discharge power amount required for the demand response. According to the lower control device 200, in this respect, the error of the implementation amount with respect to the required amount of the demand response can be reduced.

In addition, the charge / discharge control unit 295 raises the total demand response and is a demand response, and the demand power amount predicted value of the consumer installation system 300 at the execution time of the demand response (demand by consumer when the demand response is not implemented is assumed). When the electric energy forecast value) is larger than the electric energy demand target value for each consumer, the amount of electric energy required for the consumer installation system 300 during the demand response implementation time is set as the electric energy demand target value for each consumer. The discharge control of the dischargeable device 311 is stopped.
By reducing the charge power amount of the other consumer installation system 300 by the decrease in the discharge power amount due to this cancellation, the loss during charging / discharging of the power system 1 as a whole is reduced without changing the total power demand amount. It can be reduced.

In addition, the charge / discharge control unit 295 raises the total demand response and is a demand response, and the demand power amount predicted value of the consumer installation system 300 at the execution time of the demand response (demand by consumer when the demand response is not implemented is assumed). When the electric energy forecast value) is smaller than the electric energy demand target value for each consumer, it is based on the electric energy demand target value for each consumer reset in response to the cancellation of charge / discharge control by the other lower control device 200. , Control the charge / discharge of chargeable / dischargeable equipment,

In the consumer installation system 300, where the predicted power demand value (predicted power demand value for each consumer when demand response is not implemented) is smaller than the baseline for each customer, the amount of power to be charged by the chargeable / discharging device 311. Is considered to be relatively large. On the other hand, by resetting the target value of the demand power amount for each consumer, the amount of power to be charged by the chargeable / discharging device 311 becomes smaller than that before the reset. This reduces the possibility that the substantial chargeable amount will be insufficient for the charge power amount required for demand response. According to the lower control device 200, in this respect, the error of the implementation amount with respect to the required amount of the demand response can be reduced.

Further, the charge / discharge prediction unit 293 predicts the charge / discharge state of the charge / discharge possible device 311 in the peak shift based on the information of the electric power charge for each time zone. The required power amount in the demand response for each customer is determined based on the prediction result of the charge / discharge state of the chargeable / dischargeable device.
As a result, it is expected that the charge / discharge prediction unit 293 can predict the charge / discharge of the charge / discharge possible device 311 with relatively high accuracy.

Further, the charge / discharge control unit 295 sets the upper limit value set for at least one of the charge power for the peak shift and the discharge power for the peak shift in the simultaneous execution of the peak shift and the demand response. Based on this, the charge / discharge of the chargeable / dischargeable device is controlled.
As a result, the chargeable / dischargeable device 311 has at least a charge for peak shift and a charge for demand response by consumer, or a discharge for peak shift and a discharge for demand response by consumer. Either one can be performed at the same time.

Further, the second communication unit 210 further acquires information indicating whether the total demand response is an increased demand response or a decreased demand response. The charge / discharge control unit 295 charges / discharges so that the total demand response is increased and the demand response is obtained, and the demand power amount of the consumer installation system 300 at the execution time of the demand response is set as the demand power amount target value for each customer. When the charge / discharge of the possible device 311 is discharge, the total demand response is lowered and the demand response is, and the electric energy demand of the consumer installation system 300 during the execution time of the demand response is set to the electric energy demand target value for each consumer. When the charge / discharge of the charge / discharge rechargeable device 311 is charging, the charge / discharge for setting the power demand of the consumer installation system 300 at the execution time of the demand response as the target power demand target value for each customer. The charge / discharge control of the possible device 311 is stopped (at this time, the charge / discharge for purposes other than demand response continues).

In this way, the second communication unit 210 acquires information indicating whether the total demand response is an up-demand response or a down-demand response, so that the lower control device 200 increases the amount of power demand due to the total demand response. It is possible to detect the case where the increase / decrease and the increase / decrease in the amount of power demand due to the charge / discharge for the demand response in the consumer installation system 300 are opposite to each other, and stop the charge / discharge for the demand response.

By reducing the discharge power amount or the charge power amount of the other consumer installation system 300 by the decrease in the charge power amount or the discharge power amount due to this cancellation, the entire power system 1 without changing the total power demand amount. As a result, the loss during charging and discharging can be reduced.
Further, each of the lower control devices 200 is subjected to a process of detecting the case where the increase / decrease in the power demand amount due to the total demand response and the increase / decrease in the power demand amount due to the charge / discharge for the demand response in the consumer installation system 300 are opposite. The calculation load of the host control device 100 can be reduced in that it is distributed.
