(1) Contract form In order to realize a demand response (hereinafter sometimes referred to as DR) in which a consumer receiving energy supply fluctuates the amount of demand to match the energy supply-demand balance, energy is usually supplied. There is a contract for charging between the supplier side and the consumer side. For example, typical contracts that are concluded for the purpose of demand response between the power supplier that supplies power and the power consumer that receives power include the supply and demand power contract method and the hourly rate method. .

As a typical supply and demand power method that gives rewards and penalties to the customer side that meets the demands of the supplier side that supplies power, there are a prior reduction amount contract method and an adjustment amount dependent contract method. In the prior reduction amount contract method, an adjustment amount (kw × time) is contracted in advance, and if it is completed, a relatively high incentive can be obtained compared to other contract methods. In the adjustment amount-dependent contract method, when a power suppression request is received and the request is answered, an incentive can be obtained according to the reduced power amount.

On the other hand, there are real-time pricing and Time-Of-Use as typical hourly rate systems in which the unit price of electricity charges is changed according to the tightness of supply and demand. In real-time pricing, charge information is notified in real time. In Time-Of-Use, an electricity bill unit price is set in advance for each time zone.

(2) Description of Adjustment Amount As shown in FIG. 1, the adjustment amount AD that is considered to be obtained by the energy adjustment control is defined as an amount obtained by subtracting the actual energy consumption amount RV from the baseline BL. When energy adjustment control is performed, this adjustment amount AD affects the amount of charge imposed on the consumer's energy usage. The baseline BL used in this definition is the amount of energy actually consumed or assumed to be consumed by the energy consumer when the energy adjustment control is not performed. The energy adjustment control is, for example, demand response control. The energy adjustment control is performed based on information on energy adjustment control requests and energy prices from the supplier side of the energy adjustment control. The target of energy adjustment control is equipment that is operated by an energy consumer.

Generally, energy is sent from the energy supplier 1 to the energy consumer C1, the customer C2, and the customer C3 facility 3 through the energy delivery operator 2 as shown in FIG. The flow of energy from the energy supply company 1 to the energy transmission / distribution company 2 is indicated by an arrow E1, and the flow of energy from the energy transmission / distribution company 2 to each of the consumer C1, the customer C2, and the customer C3 Are indicated by arrows E2, E3, E4.

(4-2-2) Control unit 36
The control part 36 is comprised from CPU, ROM, and RAM, for example. The control unit 36 reads out and executes the program stored in the storage unit 35 described above, whereby the baseline power determination unit 36a, the power fluctuation amount prediction unit 36b, and the cost impact estimation calculation unit 36c illustrated in FIG. The functions of the device non-operation effect estimation unit 36d, the cost effect presentation unit 36e, and the time information presentation unit 36f can be exhibited.

The baseline power determination unit 36a calculates the baseline power based on the calculation method determined by the agreement with the power company 1a. For calculating the baseline power, a conventional baseline power calculation method is used, and information necessary for calculating the baseline power is obtained from the control status of the power company 1a and the device control device 30. A conventional general calculation method can be used as the calculation method of the baseline power. For example, regression that predicts the load of the day using an averaging method that is calculated based on the average value of data for multiple days in the same time period in the past, and many variables that affect the load (past load pattern, weather, day of the week, etc.) The analysis method, the same day adoption method that finds the day most similar to the current day from the past data and adopts it as the baseline, and the weighted moving average method that calculates the baseline by increasing the weight of the data close to the current day are the baseline. Conventionally known as a method of calculating power.

When there is an operation instruction for the equipment device 20 from the input unit 33 during the DR control period, the power fluctuation amount prediction unit 36b predicts the amount of power fluctuation that occurs when the equipment device 20 performs an operation based on the operation instruction. . The power fluctuation amount prediction unit 36b receives information necessary for prediction of the power fluctuation amount corresponding to the operation instruction from the operation power usage amount holding unit 35a. The power fluctuation amount prediction unit 36b has formulas or tables necessary for prediction for the air conditioner 20a, the illumination 20b, and the ventilation fan 20c, respectively. These formulas or tables are consumed by the air conditioner 20a, the illumination 20b, and the ventilation fan 20c. It is a mathematical formula or a table created by a known method conventionally known for calculating power. For example, when it is necessary to input the value of the outdoor temperature as a parameter in the calculation of the power consumption of the air conditioner 20a, if the air conditioner 20a has an outdoor temperature sensor, the measurement result of the outdoor temperature sensor uses the operation power. If the air conditioner 20a does not have the outdoor temperature sensor, the measurement result is held in the operation power usage amount holding unit 35a by the separately provided outdoor temperature sensor. As described above, information necessary for the prediction of the power fluctuation amount prediction unit 36b is collected at any time and held in the operation power usage amount holding unit 35a.

The cost impact trial calculation unit 36c applies the power fluctuation amount predicted by the power fluctuation amount prediction unit 36b to the billing calculation information, and calculates the amount of increase in billing associated with the power fluctuation amount. In the case of the adjustment amount dependent contract method of the supply and demand power contract method, for example, the device control device 30 receives a request for DR control from the power management device 10 of the power company 1a.

In the case of the adjustment amount-dependent contract method, the billing calculation information received from the power company 1a includes, for example, a DR control period and an incentive unit price. The incentive reduction amount will be described with reference to FIG. 1. First, since the target power TP is achieved until the time Td when the operation of the facility device 20 is to be changed, (target adjustment amount TAD (kW)) × (1 kWh) Incentives per unit). That is, the billing is reduced by this calculated value with respect to the billing for the power consumption at this time. However, if the operation of the equipment device 20 is changed at the time Td, an increase in power consumption is predicted by the power fluctuation amount WV accompanying the change in the operation of the equipment device 20, and the predicted actual value ERV after the change of the operation of the equipment device 20 is Only the predicted adjustment amount EAD smaller than the target adjustment amount TAD can be achieved. Therefore, a decrease in incentive corresponding to (target adjustment amount TAD−predicted adjustment amount EAD) occurs. The amount of increase in billing associated with the incentive reduction amount is (target adjustment amount TAD−predicted adjustment amount EAD) × (incentive unit price per kWh) × (remaining time). If this is expressed in a more general way, the incentive reduction amount is obtained based on the power fluctuation amount WV, the remaining time, and the incentive unit price. The reason why it is based on the power fluctuation amount WV is that the predicted adjustment amount EAD is calculated using the power fluctuation amount WV. That is, EAD = BL− (RV + WV). However, when there is a period Z in which the value of the target adjustment amount TAD−the predicted adjustment amount EAD is 0 or negative, the incentive decrease amount is 0 in the period Z. Therefore, the increase amount is calculated by subtracting the period from the remaining time. calculate.

In the case of the prior reduction amount contract method, the billing calculation information received from the power company 1a includes, for example, a DR control period. The target adjustment amount TAD is determined in advance by a contract or the like. In the case of the prior reduction amount contract method, for example, if the adjustment amount AD and the predicted adjustment amount EAD are even smaller than the target adjustment amount TAD, the prior contract cannot be fulfilled and a penalty must be paid. Therefore, as shown in FIG. 1, since the operation of the facility device 20 is changed at time Td, a certain penalty is applied regardless of the amount of the predicted adjustment amount EAD from the stage when the predicted adjustment amount EAD becomes smaller than the target adjustment amount TAD. An obligation to pay the unit price is imposed. As a result, in the case of FIG. 1, the amount of increase in charge associated with the penalty is (target adjustment amount TAD) × (penalty unit price per kWh) × (remaining time). If this is expressed in a more general manner, the penalty fee is obtained based on the power fluctuation amount WV, the remaining time, and the penalty unit price.

In the case of hourly rate method, the fee for the time zone notified from the power company 1a is set high. In this case, the billing calculation information may be received from the power company 1a as needed, or the reported billing calculation information may be stored in the storage unit 35 if notified beforehand. In the case of the time-based charge method, for example, if the electricity charge is increased uniformly for a predetermined time period, the power fluctuation amount WV accompanying the change in the operation of the equipment device 20 contributes to the increase in the electricity charge. Assuming that the remaining time in FIG. 1 is the remaining time in the time zone in which the electricity charge is temporarily increased, the power fluctuation amount WV × (electricity charge per kWh) × (remaining time) is This increases the amount of billing associated with the change in operation.

The device non-operation influence estimation unit 36d estimates the influence of device non-operation caused by not performing an operation based on the operation instruction of the equipment device. The estimation performed by the device non-operation influence estimation unit 36d will be described with reference to FIG. 7 taking an example of estimation of a change in room temperature when the air conditioner 20a is not operated. The state shown in FIG. 7 is based on the premise that the air conditioner 20a performs the cooling operation set to the set temperature until the DR control period, and the outdoor temperature is higher than the set temperature. At the start of the DR control period, the air conditioner 20a is stopped. Then, it is assumed that the consumer inputs to the input unit 33 that the operation of the air conditioner 20a is resumed at a time Td when a certain amount of time has elapsed. When the device non-operation influence estimation unit 36d is notified from the input unit 33 that there has been an operation instruction for restarting the operation of the air conditioner 20a, the device non-operation effect estimation unit 36d starts to estimate the indoor temperature rise when the air conditioner 20a is not operated. .

The device non-operation effect estimation unit 36d first calculates the slope δT from the transition of the room temperature over the elapsed time. Then, it is predicted that the room temperature will increase with the same slope, and the room temperature at the end of the DR period is predicted by multiplying the slope δT by the remaining time (δT × (remaining time)). At this time, as a method of predicting the slope δT, for example, the device non-operation effect estimating unit 36d calculates an approximate line using a least square method. Further, as another method of predicting the slope δT, from the past control history stored in the device non-operation influence information holding unit 35b when the device control device 30 controls the facility device 20 in the past, The result of control under the same condition is extracted by the device non-operation effect estimation unit 36d, and the result is calculated as the room temperature at the end of the DR period.

The cost effect presentation unit 36e presents the cost effect on the billing related to the amount of power consumed by the facility device 20 when the facility device 20 performs an operation based on the operation instruction received by the input unit 33. Specifically, the cost impact presentation unit 36e presents the result of the trial calculation performed by the cost impact trial calculation unit 36c and the result of the above estimation performed by the device non-operation impact estimation unit 36d. Details of the presentation of the cost impact by the cost impact presentation unit 36e will be described later.

The time information presentation unit 36f presents the DR control start time or the elapsed time from the start of the DR control as time information related to the DR control. As a presentation method, for example, the time information presentation unit 36f displays on the display of the output unit 32 the end time of DR control, the remaining time, the start time and the required time, or the elapsed time and the required time. Information necessary for presenting time information related to DR control is received by the time information presentation unit 36f from the DR control information holding unit 35c.

(5) Presentation of cost impact (5-1) Case where only the availability of operation of equipment is determined In the following description, a case in which some assumptions are further added to the case already described with reference to FIG. 7 will be described. That is, until the DR control period (for example, the time zone from 13:00 to 14:00), the air conditioner 20a of the property A performs the cooling operation while maintaining the room temperature at the set temperature, and the outdoor temperature is higher than the set temperature. High. At the start of the DR control period, the air conditioner 20a is stopped. Then, it is assumed that the user inputs to the input unit 33 that the air conditioner 20a restarts the cooling operation at a time Td when a certain amount of time has elapsed. The set temperature is assumed to be 26 ° C. The property A is assumed to be an object of the adjustment amount dependent contract method.

FIG. 8 shows a screen of the display 32a of the output unit 32 that displays the influence of the cost and the non-operation of the device. On the screen of the display 32 a in FIG. 8, the contents related to the cost effect presented by the cost impact presentation unit 36 e when the above input is input to the input unit 33 are displayed. The display of the display 32a of the output unit 32 is performed using an input of an operation instruction of the air conditioner 20a to the input unit 33 as a trigger.

Next, processing until the display 32a is displayed will be described. When the above information is input to the input unit 33, the power fluctuation amount prediction unit 36b receives necessary information from the operation power usage amount holding unit 35a, and cools the air conditioner 20a of the property A at a set temperature of 26 ° C. Estimate the amount of power fluctuation when starting operation. For example, the target adjustment amount TAD requested by the electric power company 1a is 1000 kW, the current adjustment amount AD is 1200 kW, and the cooling operation of the air conditioner 20a is started at a set temperature of 26 ° C. Assume that 36b predicts that there is an increase in the amount of power used with a power fluctuation amount of 400 kW. Then, the power fluctuation amount prediction unit 36b predicts (target adjustment amount TAD−predicted adjustment amount EAD) becomes 200 kW.

In this case, if the incentive unit price is 10 yen per kWh, the incentive decrease calculated by the cost impact trial calculation unit 36c is 200 * 10 * 0.5 = 1000 yen. In addition, it is assumed that the device non-operation influence estimation unit 36d estimates the room temperature at the end of the DR control as 28 ° C. using information obtained from the device non-operation influence information holding unit 35b.

When the estimation as described above is performed, the cost impact presentation unit 36e, as shown in the display 32a of FIG. 8, the incentive reduction amount calculated by the cost impact trial calculation unit 36c and the device non-operation impact estimation unit 36d. The room temperature at the end of the DR control estimated by is displayed. At the same time, the cost impact presentation unit 36e confirms the selection of the operation of the equipment 20 to the consumer, and displays the button 32b “operate” and the button 32c “do not operate” on the display 32a (touch screen). indicate. When the consumer presses the button 32b of the display 32a, the cooling operation of the air conditioner 20a is started from 13:30. On the other hand, if the consumer presses the button 32c of the display 32a, the cooling operation stop state of the air conditioner 20a is continued until 14:00.

As a result of the calculation by the cost impact trial calculation unit 36c, if there is no effect even if the air conditioner 20a is restarted under the above conditions, that is, the calculation result that the incentive reduction amount is 0 yen is obtained, the cost impact presentation For example, the unit 36e displays on the display 32a the content “no influence” as shown in FIG. In this case, the user may confirm the selection of the operation of the equipment 20 by the method as shown in FIG. 8, but since there is no effect on the cost, the consumer is as shown in FIG. You may omit the confirmation.

(5-2) When the operation content of the equipment is selected Next, a case where the consumer selects the operation of the equipment 20 from a plurality of types of operation content will be described with reference to FIG. As a premise, until the DR control period (for example, from 13:00 to 14:00), the air conditioner 20a of the property A is performing the cooling operation at the set temperature of 26 ° C., and the outdoor temperature is higher than the set temperature. To do. At the start of the DR control period, the air conditioner 20a is stopped. When a certain amount of time has elapsed, unlike the case described in (5-1), it is assumed that the consumer has input to the input unit 33 that the air conditioner 20a is simply restarted. The property A is assumed to be an object of the adjustment amount dependent contract method.

FIG. 10 shows a screen of the display 32a of the output unit 32 displaying the influence of cost and the influence of non-operation of equipment. On the screen of the display 32 a in FIG. 10, the contents related to the cost effect presented by the cost impact presentation unit 36 e when the above input is input to the input unit 33 are displayed. The display of the display 32a of the output unit 32 is performed using an input of an operation instruction of the air conditioner 20a to the input unit 33 as a trigger.

Next, processing until the display 32a is displayed will be described. When the above-described information is input to the input unit 33, the cost impact presentation unit 36e determines the operation contents that can be selected when the air conditioner 20a starts operation. Here, in addition to the operation content for resuming the cooling operation at the set temperature of 26 ° C., the air supply operation and the operation content for resuming the cooling operation at the set temperature of 28 ° C. are determined by the cost effect presentation unit 36e. The operation content to be determined is stored in the storage unit 35 in advance. For example, when there is an operation instruction to restart the operation of the air conditioner 20a during the DR control period, It may be determined that the operation at the set temperature added twice to the set temperature at the start of the control period is displayed.

The power fluctuation amount prediction unit 36b receives necessary information from the operation power usage amount holding unit 35a, and starts the cooling operation of the air conditioner 20a of the property A at the set temperature 26 ° C. and the set temperature 28 ° C. Estimate the amount of power fluctuation when starting. In addition, the device non-operation influence estimation unit 36d estimates the room temperature at the end of the DR control using information obtained from the device non-operation influence information holding unit 35b.

When the above estimation is performed, the cost impact presentation unit 36e, as shown in the display 32a of FIG. 10, the incentive reduction amount calculated by the cost impact trial calculation unit 36c and the device non-operation impact estimation unit 36d. The room temperature at the end of the DR control estimated by is displayed. At the same time, the cost impact presentation unit 36e displays

buttons

32c, 32d, 32e, and 32f on the display 32a (touch screen) in order to confirm the selection of operation of the equipment 20 to the consumer. If the consumer presses the button 32c of the display 32a, the cooling operation stop state of the air conditioner 20a is continued until 14:00. If the consumer presses the button 32d of the display 32a, the air blowing operation of the air conditioner 20a starts at 13:30, and if the user presses the button 32e, the cooling operation starts at 13:30 with the set temperature of 28 ° C., and the button 32d is pressed. For example, the cooling operation is started at 13:30 at a set temperature of 26 ° C.

As a result of the calculation by the cost impact trial calculation unit 36c, if there is no effect even if the air conditioner 20a is restarted under the above conditions, that is, the calculation result that the incentive reduction amount is 0 yen is obtained, the cost impact presentation For example, the unit 36e displays on the display 32a the content “no influence” as shown in FIG.
