Description

  The present invention relates to a processing device, a processing method, and a program.

  Various services for controlling the operation of storage batteries owned by consumers are being studied. For example, there is a service (hereinafter referred to as “energy management service”) that controls charging and discharging of a storage battery such that charging is performed during a time period when the electricity charge (electric power unit price) is relatively low and discharging is performed during a relatively high time period. According to the service, the consumer can reduce the electricity bill paid to the electric power company.

  In addition, there is a service (hereinafter referred to as "ancillary service") that controls charging/discharging of a storage battery in order to adjust the supply and demand balance of the power system. That is, the storage battery of the consumer is used as the adjustment power or reserve power for adjusting the supply and demand balance of the power system. This service is a service for power transmission and distribution companies. It should be noted that by paying a predetermined incentive to the customer who provided the storage battery for the service, it can be regarded as a service for the customer.

  In addition, a service that controls charging/discharging of a storage battery (hereinafter, “imbalance avoidance service”) can be considered based on a request from a retail electric power company. If it is difficult to achieve the same amount for 30 minutes by adjusting its own system, the retail electric power company will ask the business operator who provides the service to the storage battery of the customer that the retail electric power company has a power supply contract. , Request a predetermined amount of charge or discharge at a predetermined timing. Based on the request, the business operator who provides the service controls the storage battery of the consumer to charge or discharge a predetermined amount at a predetermined timing. This service is for retail electric utilities. It should be noted that by paying a predetermined incentive to the customer who provided the storage battery for the service, it can be regarded as a service for the customer.

  In addition, a service (hereinafter, “excess power absorption service”) that controls charging/discharging of a storage battery can be considered based on a request from a power generation company that has a power generation device that uses natural energy (eg, sunlight). The power transmission and distribution company can request the power generation company to suppress the output (reduce the reverse flow to the power system) when there is a possibility that the supply and demand operation of the power system will be hindered. The power generation company that has received the request for the output suppression requests the company that provides the service to charge the amount that needs to be suppressed during the time period when the output is suppressed. Then, the power generation company outputs the output as usual without suppressing the output even during the time period when the output is suppressed. Based on the above request, the business operator who provides the service controls the storage battery of the consumer and charges the amount that needs to be suppressed during the time period when the output is suppressed. This service is a service for power generation companies. It should be noted that by paying a predetermined incentive to the customer who provided the storage battery for the service, it can be regarded as a service for the customer.

Based on the charge/discharge control schedule, the control device that controls the storage battery predicts the time when the electricity rate is high when the difference between the time when the electricity rate is the highest and the time when the electricity rate is the lowest is a certain amount or more. The storage battery is controlled so that the power corresponding to the power consumption is charged in the other time zone and discharged in the time zone when the electricity rate is high.

  Patent Document 2 discloses an ancillary service providing device that provides ancillary services in consideration of the life of a storage battery.

In addition to the "measured value of the amount [Wh] (second measured value)", "at least one kind of charge/discharge command value [W]" is acquired, and based on these, the electric energy [Wh] of various electric powers is calculated. To do.

  Hereinafter, the configuration of this embodiment will be described in detail. First, an example of a customer facility will be described with reference to FIG. As illustrated, the customer facility includes a control device, a PCS, a storage battery, a load, a measuring device (“M1” in the figure), and a distribution line. In the figure, solid lines indicate distribution lines, and dotted lines indicate communication lines. The communication can be wired and/or wireless. The communication standard is not particularly limited. Note that the customer facility may include other devices.

  The measuring device M1 is installed on the upstream side of the electric power customer facility, and includes “the amount of electric power [Wh] of electric power supplied from the electric power system to the electric power customer facility” and “electric power supplied from the electric power customer facility to the electric power system. Power [Wh]” and the like. The measuring device is, for example, a smart meter, and measures an integrated value every predetermined time (eg, 30 minutes). The connection point side of the distribution line of the power consumer facility with the power system is referred to as the upstream side, and the destination to which the power supplied from the power system flows is referred to as the downstream side (hereinafter the same).

  The load is a device that operates on electric power, and examples thereof include, but are not limited to, a television, an air conditioner, a refrigerator, and lighting.

  The control device controls consumer equipment, manages various data relating to consumer equipment, and the like. The PCS controls charge/discharge of the storage battery.

  At least one of the control device and the PCS calculates a charging/discharging command value [W] indicating electric power for charging or discharging the storage battery corresponding to various purposes, repeatedly in a predetermined cycle or in an indefinite cycle. Examples of various purposes include, but are not limited to, LFC control of energy management service, GF control of energy management service, ancillary service, imbalance avoidance service, surplus power absorption service, and the like.

  When both the control device and the PCS calculate the charge/discharge command value [W], the charge/discharge command value [W] corresponding to different purposes are calculated. For example, the PCS calculates the charging/discharging command value [W] for the GF control of the energy management service, and the control device controls the charging/discharging command value [W] for the LFC control of the energy management service and other charging/discharging purposes. The command value [W] may be calculated.

  Then, the control device or the PCS integrates a plurality of types of charge/discharge command values [W] based on a plurality of types of charge/discharge command values [W] for charging/discharging at the same timing, and integrates the charge/discharge command values [W]. To calculate. Then, the PCS controls the storage battery to charge or discharge with the integrated charge/discharge command value [W].

  Here, an example of a process of calculating various charge/discharge command values [W] and a process of calculating the integrated charge/discharge command value [W] will be described.

<Charge/discharge command value [W] for LFC control (ancillary service)>
Ancillary services are mainly services for power transmission and distribution companies. Ancillary services control the charging and discharging of storage batteries to adjust the supply and demand balance of the power system. That is, in the case of excessive demand, the storage battery is caused to discharge and perform the operation of supplying power to the power system. On the other hand, in the case of excessive supply, the storage battery is made to consume the electric power by causing the storage battery to perform the charging operation.

  The control device of each customer facility calculates the charge/discharge command value [W] for LFC control based on the information received from the central control device that integrally controls the storage batteries of the plurality of customer facilities.

First, the central control unit repeatedly determines the upper limit a _{max_n} of power input/output for LFC control in a predetermined cycle (for example, 15 minutes) corresponding to each of the plurality of storage batteries to be controlled. Then, the central control device repeatedly transmits the determined upper limit a _{max_n} to each control device in a predetermined cycle (for example, 15 minutes).

In addition, the central control unit repeatedly calculates A _max, which is the sum of the upper limits a _{max — n} of each of the plurality of storage batteries, in a predetermined cycle (for example, 15 minutes), and a predetermined cycle (for example, 15 minutes) in the system of the power transmission and distribution company. To send repeatedly.

Further, the central control device repeatedly receives the LFC signal from the system of the power transmission and distribution company at a predetermined cycle (for example, several seconds) or at an indefinite cycle. The LFC signal includes a command value [W] of electric power charged or discharged by a plurality of storage batteries. The system of the power transmission and distribution company determines the command value [W] within the range of A _max or less received from the central control device and transmits it to the central control device. The LFC signal can identify the operation content (charging and discharging). For example, a positive value may be used for charging and a negative value may be used for discharging.

In response to the reception of the LFC signal, the central control unit calculates a value B obtained by dividing the command value [W] specified by the LFC signal by A _max . Then, the central control device broadcasts the calculated value B to the plurality of control devices. The transmission of the value B is repeated in a predetermined cycle (for example, several seconds) or in an indefinite cycle. As a means for realizing the simultaneous transmission, for example, multicast, broadcast using FM communication, or other method can be used.

Each control device receives a charge/discharge command for LFC control based on a _{max_n} , which is repeatedly received in a predetermined cycle (eg, 15 minutes), and a value B, which is repeatedly received in a predetermined cycle (eg, several seconds) or is received in an indefinite cycle. Calculate the value [W]. Specifically, the control device calculates the product of a _{max_n} and B as a charge/discharge command value [W] for LFC control.

As a modified example of the example, the system of the power transmission and distribution company has a value obtained by dividing the command value [W] by A _max instead of the LFC signal including the command value [W] of the electric power charged or discharged by the plurality of storage batteries. The LFC signal including B may be transmitted to the control device. Then, the central control device may broadcast the received value B to a plurality of control devices without executing the process of calculating the value B.

As another modification, the central control device may repeatedly transmit A _max to a plurality of control devices at a predetermined cycle (eg, 15 minutes) in addition to a _{max_n} determined corresponding to each storage battery. Then, when the LFC signal including the command value [W] of the electric power charged or discharged by the plurality of storage batteries is received from the system of the power transmission and distribution company, the central control device divides the command value [W] by A _max. Instead of B, the command value [W] may be broadcast to a plurality of control devices. Then, each control device may calculate the charge/discharge command value [W] for the LFC control by multiplying the value B obtained by dividing the command value [W] by A _max by a _{max_n} .

As another modification, the central control unit, a _{a Max_n} determined in correspondence with each accumulator _may calculate the value _{d n} divided by _{A max.} Then, the central control _unit, instead of _{a Max_n,} the _{d n,} a predetermined period to a plurality of control devices: may be repeatedly transmitted in (Example 15 minutes). Then, when receiving the LFC signal including the command value [W] of the power to be charged or discharged by the plurality of storage batteries from the system of the power transmission and distribution company, the central control device sends the command value [W] to the plurality of control devices. You may send it all at once. Each controller is multiplied by the d _n to the command value [W], may calculate the charging and discharging command value for the LFC control [W].

  Here, the example in which the control device calculates the charge/discharge command value [W] for the LFC control has been described, but the PCS receives various information from the control device, and the charge/discharge command value [L] for the LFC control is displayed. W] may be calculated.

<Charge/discharge command value [W] for GF control (ancillary service)>
First, the central controller repeatedly determines the upper limit c _{max — n} of power input/output for GF control in a predetermined cycle (for example, 15 minutes) corresponding to each of the plurality of storage batteries to be controlled. After that, the central controller determines the content of the GF control for each storage battery. Specifically, the central control unit determines the charging/discharging command value [W] of the electric power [W] charged or discharged by each storage battery according to the degree of deviation from the reference value of the system frequency (GF control information ( (Example: function, correspondence table, etc.) is generated. In the GF control information, the maximum value of power input/output is determined to be equal to or less than the upper limit c _{max — n} . The central controller transmits the GF control information corresponding to each of the plurality of controllers.

  Upon receiving the GF control information from the central control unit, each control device transmits the GF control information to the PCS. The PCS repeatedly receives the measured value of the system frequency in a predetermined cycle (for example, several tens of milliseconds) from an internal sensor or a measurement sensor installed near the own device. Then, the PCS repeatedly calculates the deviation of the system frequency from the reference value based on the measured value and the reference value given in advance. Further, the control device calculates the charge/discharge command value [W] for the GF control based on the calculated deviation and the GF control information.

  Here, the example in which the PCS calculates the charge/discharge command value [W] for GF control has been described, but the control device may calculate the charge/discharge command value [W] for GF control.

<Charge/discharge command value [W] for energy management service>
Energy management service is a service for customers. In this service, the storage battery is caused to perform a charging/discharging operation of charging electric power during a time period when the unit price of electricity is relatively low and discharging electric power during a time period when the unit price of electricity is relatively high.

  The control device generates a charging/discharging schedule in which electric power is charged in a time period in which the unit price of electricity is relatively low, and electric power is discharged in a time period in which the unit price of electricity is relatively high. For example, the control device may set a time zone in which the unit price of electric power is higher than a predetermined value as a time zone for discharging, and a time zone in which the unit price is less than or equal to the predetermined value as a time zone for charging. The predetermined value is, for example, an average value of power unit prices (eg, “Q1 yen/kWh” from P1 to P2, “Q2 yen/kWh” from P2 to P3,...) Set for each time zone ( It may be an average value of Q1, Q2,... Or a value given to the control device in advance.

  Then, the control device performs charging within a time period for charging and discharging during a time period within a range satisfying a predetermined upper limit (upper limit of power input/output for energy management service predetermined for each storage battery) or less. A charging/discharging schedule for discharging is generated. In addition, in these charge and discharge, it is preferable that the integrated charge amount be as large as possible within a range in which one day is a cycle and the upper limit of electric power that can be charged by the energy management service (for example, SOC can be charged up to 95%) is not exceeded. In addition, it is preferable that the integrated discharge amount be as large as possible within a range that does not exceed the upper limit of the electric power that can be discharged by the energy management service (eg, SOC can be discharged up to 5%).

  The system of the business operator that provides the energy management service may generate the charge/discharge schedule by the method as described above. Then, the control device may receive the charge/discharge schedule from the system.

  The control device specifies the charge/discharge command value [W] for the energy management service at each timing based on the charge/discharge schedule. In the charging time period, for example, the charging power [W] at each timing defined by the charge/discharge schedule is specified as the charging command value [W] for the energy management service at each timing. On the other hand, in the time zone for discharging, for example, in the range of “the upper limit value [W] of the discharge power at each timing determined by the charge/discharge schedule” or less, “the load at the time measured by the predetermined measurement sensor The "total power consumption [W]" is specified as the discharge command value [W] for the energy management service at each timing (this is called load following discharge).

  The PCS may specify the charge/discharge command value [W] for the energy management service at each timing based on the charge/discharge schedule.

<Charge/discharge command value [W] for imbalance avoidance service>
The imbalance avoidance service is a service for retail electric utilities. If it is difficult to achieve the same amount for 30 minutes by adjusting the system, the retail electric power company asks the business operator who provides the service to charge the storage battery of the customer with whom the retail electric power supplier has a power supply contract. Then, a predetermined amount of charge or discharge is requested at a predetermined timing. Based on the request, charge/discharge of the storage battery of each consumer is controlled.

  The central control unit causes the battery to be charged by the imbalance avoidance service based on information indicating the state (eg, SOC) of each storage battery that is repeatedly received from a plurality of control units in a predetermined cycle, the future power demand prediction of each consumer, and the like. The latest values of the amount of power that can be discharged and the amount of discharge that can be discharged, and the estimated value in each future time zone are grasped for each storage battery. The central control unit then adds them together to obtain the latest values such as the amount of electric power that can be charged by the entire plurality of storage batteries and the amount of discharge that can be discharged, and the estimated value in each future time zone. To calculate.

  The central controller transmits the calculated result to the system of the retail electric power supplier in advance. The system of the retail electric power company makes a request for avoiding imbalance (a predetermined amount of discharging or charging at a predetermined timing) within a range not exceeding the upper limit indicated by the result.

  Based on the above request, the central control device specifies the electric energy [Wh] for charging or discharging and the time zone. Then, the central control device selects a storage battery to be charged or discharged based on the content of the request and the amount of charge and/or discharge that can be charged and discharged in each storage battery, and also causes each storage battery to be charged or discharged. The electric energy [Wh] is determined. Then, the central control device generates a charging/discharging schedule for charging or discharging the determined amount of electric power within the time period, and transmits each charging/discharging schedule to each control device. The charging/discharging schedule of each storage battery is generated such that the power input/output meets a predetermined upper limit (upper limit of the power input/output for the imbalance avoidance service predetermined for each storage battery) or less.

  Each control device receives the charge/discharge schedule for the imbalance avoidance service. Then, each control device specifies the charge/discharge command value [W] for the imbalance avoidance service at each timing based on the charge/discharge schedule. The PCS may specify the charge/discharge command value [W] for the imbalance avoidance service at each timing based on the charge/discharge schedule.

<Charge/discharge command value for surplus power absorption service>
The surplus power absorption service is a service for power generation companies that have a power generation device that uses natural energy (eg, sunlight). Upon receiving a request for output suppression (suppression of reverse power flow to the power system) from the power transmission and distribution company, the power generation company requests the business operator that provides the service to perform charging to avoid the output suppression. Based on the request, charge/discharge of the storage battery of each consumer is controlled.

  The central control unit receives the output curtailment request sent to the power generation company. In the output suppression request, a suppression time period (eg, next day 1 day, next day 13:00 to 16:00, etc.) is set. The amount to be suppressed may be, for example, a case where the output is “0” or a case where the upper limit of the output (XX% of the rated output) is set for each unit time zone (for example, 30 minutes).

  In addition, the central control unit acquires the power generation prediction (eg, the power generation prediction for the next day) of each power generation company. For example, the central control device may receive from the system of each power generation company, or may generate it by its own device.

  Then, the central control device calculates the electric power suppressed at each timing, that is, the electric power to be charged at each timing, based on the content of the output suppression request and the power generation prediction. After that, the central control unit generates the charging schedule for each of the plurality of storage batteries by allocating the electric power to be charged at each timing to the plurality of storage batteries. Then, the central control device transmits each charging schedule to each control device. In addition, the charging schedule of each storage battery is generated so that the power input/output satisfies a predetermined upper limit (upper limit of power input/output for a surplus power absorption service predetermined for each storage battery).

  Each control device receives the charging schedule for the surplus power absorption service. Then, each control device specifies the charge/discharge command value [W] for the surplus power absorption service at each timing based on the charging schedule. The PCS may specify the charge/discharge command value [W] for the surplus power absorption service at each timing based on the charging schedule.

<Integrated charge/discharge command value [W]>
At least one of the control device and the PCS controls the plurality of types of charge/discharge command values [W] described above (charge/discharge command value [W] for LFC control, charge/discharge command value [W] for GF control, energy management 2 or more of charge/discharge command value [W] for service, charge/discharge command value [W] for imbalance avoidance service, charge/discharge command value [W] for surplus power absorption service, etc.) Is calculated.

  At least one of the control device and the PCS calculates an integrated charge/discharge command value [W] based on the calculated plurality of types of charge/discharge command values [W]. Specifically, the integrated charge/discharge command value [W] is calculated based on a plurality of types of charge/discharge command values [W] that are charged or discharged at the same timing.

  As an example, the control device or the PCS may calculate the integrated charge/discharge command value [W] by adding together a plurality of types of charge/discharge command values [W] to be charged or discharged at the same timing. For example, one of the discharge command value [W] and the charge command value [W] is shown as a positive value and the other is shown as a negative value, and a plurality of types of charge/discharge command values [W] are added together. It

  In addition, the control device or the PCS may calculate the integrated charge/discharge command value [W] based on the priorities set in advance for the plurality of charge/discharge command values [W]. That is, when there are a plurality of types of charge/discharge command values [W] to be charged or discharged at the same timing, the control device or the PCS selects the charge/discharge command value [W] with the highest priority among them as the integrated charge/discharge command. The value [W] may be used.

  In addition, the control device or the PCS may calculate the integrated charge/discharge command value [W] based on the priorities determined in advance for the plurality of services. That is, when there are a plurality of types of charge/discharge command values [W] to be charged or discharged at the same timing, the control device or the PCS, based on the charge/discharge command value [W] for the service with the highest priority among them, The integrated charge/discharge command value [W] may be calculated. As in the ancillary service, a plurality of types of charge/discharge command values [W] corresponding to one service (charge/discharge command value [W] for LFC control and charge/discharge command value for GF control [ W]) exists, and there is one type of charge/discharge command value [W] corresponding to one service such as energy management service, imbalance avoidance service, and surplus power absorption service. is there. Therefore, the example in which priorities are given to services is different from the above example in which the charge/discharge command value [W] is given priorities in operation and effect.

  When the service having the highest priority has a plurality of types of charge/discharge command values [W], such as an ancillary service, the control device or the PCS adds the values to the integrated charge/discharge command value [W]. W].

  On the other hand, when the service having the highest priority has one type of charge/discharge command value [W], the control device or the PCS integrates one type of charge/discharge command value [W] corresponding to the service. It can be the command value [W].

  For example, the control device or the PCS that calculates the integrated charge/discharge command value [W] causes the processing device 10 to store at least one of the charge/discharge command value [W] used to calculate the integrated charge/discharge command value [W]. You may send it. The charge/discharge command value [W] is used to calculate the electric energy [Wh] of various electric power. The charging/discharging command value [W] that was not used to calculate the integrated charging/discharging command value [W] (eg, the charging/discharging command value [W] that was not used because the priority is low) is stored in the processing device 10. Not sent to. That is, it is not used for calculating the electric energy [Wh] of various electric power.

  The charging/discharging command value [W] is used to identify the charging/discharging instruction content (charging or discharging) by, for example, one of charging and discharging being represented by a positive value and the other being represented by a negative value. It is possible.

  Further, the upper limit of the value is set in advance corresponding to various charge/discharge command values [W]. In the case of the configuration for calculating the integrated charge/discharge command value [W] by adding the plurality of kinds of charge/discharge command values [W], the upper limit of each of the plurality of kinds of charge/discharge command values [W] to be added is the sum of them. It is set to be less than the rated output of PCS. On the other hand, in the case of a configuration in which any one charge/discharge command value [W] is determined as the integrated charge/discharge command value [W] based on a predetermined priority order, for example, the charge/discharge command value [W] The upper limit of may be the rated output of PCS.

  Next, the configuration of the processing device of the present embodiment having a function of calculating the electric energy [Wh] of various electric power will be described. The processing device may be provided, for example, in the control device shown in FIG. 2 or may be provided in a host device that collects information from a plurality of control devices.

  FIG. 3 shows an example of a functional block diagram of the processing device 10. As illustrated, the processing device 10 includes an acquisition unit 11 and a calculation unit 12.

  The acquisition unit 11 supplies a first measurement value obtained by measuring the amount of electric power [Wh] supplied from the electric power system to the electric power consumer equipment within the predetermined period, and the electric power supplied from the electric power consumer facility to the electric power system within the predetermined period. The second measured value of the measured electric energy [Wh] and at least one kind of charge/discharge command value [W] are acquired.

  The acquisition unit 11 can acquire the first measurement value and the second measurement value measured by the measurement device M1 in FIG.

  In addition, the acquisition unit 11 can acquire at least one of the various charge/discharge command values [W] calculated by at least one of the control device and the PCS in FIG. 2. The acquisition unit 11 acquires a plurality of charge/discharge command values [W] calculated for charging/discharging within the predetermined period, corresponding to various charge/discharge command values [W] to be acquired. Each of the plurality of charge/discharge command values [W] can specify the timing (eg, date and time) at which the PCS and the storage battery operate based on the charge/discharge command value [W]. For example, information indicating the above timing may be associated with each charge/discharge command value [W].

  The calculation unit 12 calculates the electric energy [Wh] of various electric power based on the information acquired by the acquisition unit 11. In the present embodiment, the type of power and the calculation method for calculating the power amount [Wh] are not particularly limited, and any method can be adopted (a specific example will be described in the following examples).

  In the case of the present embodiment in which the electric energy [Wh] of various electric powers is calculated using the charge/discharge command value [W], based on the integrated charge/discharge command value [W] and the integrated charge/discharge command value [W]. It is preferable to have a configuration in which the output value [W] from the PCS at the time of operation (charging or discharging) matches or the difference becomes smaller than a predetermined level. In the present embodiment, details of the configuration are design matters.

  Next, the function and effect of this embodiment will be described. In the processing device 10 of the present embodiment, “a measured value (first measured value) of the electric energy [Wh] supplied from the electric power system to the electric power customer facility” and “supplied from the electric power customer facility to the electric power system”. In addition to the “measured value (second measured value) of the electric energy [Wh]”, “at least one kind of charge/discharge command value [W]” is acquired, and the electric energy [Wh] of various electric powers is obtained based on these. It can be calculated.

  It is possible to calculate the electric energy [Wh] of various electric powers by a predetermined calculation using these pieces of information. For example, the amount of electric power [Wh] to be charged to the electric power consumer, the amount of electric power to be incentive to pay the electric power consumer [Wh], the amount of electric power charged for various services [Wh], and various types. Any kind of discharge power [Wh] corresponding to the service, power [Wh] obtained by adding two or more of these, or power [Wh] obtained by subtracting any one of these The electric energy [Wh] of the electric power can be calculated.

<Second Embodiment>
As in the first embodiment, the processing device 10 according to the present embodiment includes a “measured value (first measured value) of the electric energy [Wh] supplied from the power system to the electric power consumer facility” and an “electric power consumer facility”. In addition to the measured value (second measured value) of the electric energy [Wh] supplied from the power system to the electric power system, "at least one kind of charge/discharge command value [W]" is acquired, and based on these, various electric power is obtained. [Wh] is calculated.

  Note that the processing device 10 of the present embodiment supplies “measured value (first measured value) of the electric energy [Wh] supplied from the power system to the power customer facility” and “supplied from the power customer facility to the power system. The measured value (second measured value) of the generated electric energy [Wh]” may not be acquired. Then, the electric energy [Wh] of various electric power may be calculated based on "at least one kind of charge/discharge command value [W]".

  By the way, there may be a situation where the input/output of electric power from the PCS does not meet the integrated charge/discharge command value [W] due to a failure of an arbitrary device (eg, PCS, storage battery) in the customer facility. For example, electric power [W] smaller than the integrated charge/discharge command value [W] may be input/output, or electric power [W] larger than the integrated charge/discharge command value [W] may be input/output.

  Under such circumstances, it is not preferable to calculate the electric energy [Wh] of various electric powers based on the various charge/discharge command values [W]. The processing device 10 of the present embodiment has a configuration that eliminates such inconvenience.

  In the present embodiment, the actual charge/discharge value [W] (the actual value of the power [W] output from the PCS or input to the PCS) is measured at an arbitrary position on the distribution line. Then, based on the integrated charge/discharge command value [W] and the actual charge/discharge value [W], a correction coefficient for calculating the actual charge/discharge value [W] from the integrated charge/discharge command value [W] is calculated.

  As a modified example of the above-described processing, at an arbitrary position on the distribution line, the measured charge/discharge value [Wh] (the measured value of the electric energy [Wh] output from the PCS and/or the electric energy [Wh] input to the PCS The actual measurement value) may be measured. Then, the integrated value [Wh] of the integrated discharge command value [W], which is a discharge instruction in the integrated charge/discharge command value [W], and the actual charge/discharge value [Wh] (the electric energy [Wh] output from the PCS. Of the integrated discharge command value [W] from the integrated value [Wh] of the integrated discharge command value [Wh] (the measured value of the electric energy [Wh] output from the PCS) The coefficient may be calculated.

  In addition, the integrated value [Wh] of the integrated charge command value [W], which is the charging instruction in the integrated charge/discharge command value [W], and the actual charge/discharge value [Wh] (the electric energy [Wh] input to the PCS. Of the integrated charge command value [W] from the integrated value [Wh] of the integrated charge command value [W] to calculate an actual charge/discharge value [Wh] (actual value of the electric energy [Wh] input to the PCS). The coefficient may be calculated.

  The processing device 10 acquires the correction coefficient. For example, the processing device 10 may calculate the correction coefficient. Then, in the process of calculating the electric energy [Wh] of each type of electric power, the processing device 10 replaces "at least one type of charge/discharge command value [W]" with "at least one type of charge after correction with the correction coefficient." The discharge command value [W]" is used.

  FIG. 4 shows an example of a customer facility having a configuration capable of calculating the correction coefficient. As shown in the figure, the customer facility of this example is different from the customer facility shown in FIG. 2 in that it has a measuring device M2. Other configurations of the customer facility are similar to those of the customer facility shown in FIG.

  The measuring device M2 is installed on the distribution line near the PCS, and measures the power output from the PCS (power flowing in one direction on the distribution line) and power input to the PCS (power flowing in the opposite direction on the distribution line). The measured value [W] and/or the integrated value [Wh] of these are measured. The measuring device M2 is, for example, a smart meter or a measuring sensor.

  An example of a functional block diagram of the processing apparatus 10 of the present embodiment is shown in FIG. 3 as in the first embodiment.

  The acquisition unit 11 measures the measurement value (measurement value of charge/discharge) measured by the measurement device M2, that is, the measurement value [W] of the power output from the PCS or the power input to the PCS, and/or the integration thereof. Obtain the value [Wh]. Moreover, the acquisition part 11 acquires at least 1 type of charge/discharge command value [W] like 1st Embodiment. The acquisition unit 11 can further acquire the measurement value measured by the measurement device M1. The acquisition unit 11 may not acquire the measurement value measured by the measurement device M1.

  The calculation unit 12 can calculate a correction coefficient for calculating the actual charge/discharge value [W] from the integrated charge/discharge command value [W]. For example, the calculation unit 12 may calculate a value obtained by dividing the actual charge/discharge value [W] by the integrated charge/discharge command value [W] as the correction coefficient.

  In addition, the calculation unit 12 calculates the charge/discharge measured value [Wh] (measured value of the electric energy [Wh] output from the PCS) as an integrated discharge command value that is a discharge instruction in the integrated charge/discharge command value [W]. A value obtained by dividing the integrated value [Wh] of [W] may be calculated as the correction coefficient. In addition, the calculation unit 12 calculates the charge/discharge measured value [Wh] (measured value of the electric energy [Wh] input to the PCS) as an integrated charge command value that is a charging instruction in the integrated charge/discharge command value [W]. A value obtained by dividing the integrated value [Wh] of [W] may be calculated as the correction coefficient.

  Then, the calculation unit 12 uses “at least one type of charge/discharge command value [W] after correction with the correction coefficient” in place of “at least one type of charge/discharge command value [W]”. The electric energy [Wh] is calculated. For example, the calculation unit 12 calculates the product of the charge/discharge command value [W] and the correction coefficient as the corrected charge/discharge command value [W]. The corrected charge/discharge command value [W] is a value that well represents the power [W] actually output from the PCS or the power [W] input to the PCS based on the charge/discharge command value [W]. ..

  The calculation unit 12 calculates a correction coefficient for each predetermined time period, and calculates the electric energy [Wh] of various electric powers based on the charge/discharge command value [W] after correction with the correction coefficient corresponding to each time period. You may.

  When the deviation between the "integrated charge/discharge command value [W]" and the "charge/discharge actual measurement value [W]" changes over time, a correction coefficient is calculated every predetermined time, and the correction coefficient is calculated every predetermined time. By calculating the electric energy [Wh] of various electric powers on the basis of the corrected charge/discharge command value [W], the electric energy [Wh] of various electric powers can be calculated more accurately. In addition, if the above-mentioned deviation changes according to the attributes (eg, temperature, humidity, etc.) of various time zones (eg, morning time zone, daytime time zone, night time zone), it is corrected according to various time zones By calculating the coefficient and calculating the electric energy [Wh] of various electric power based on the charge/discharge command value [W] after correction with the correction coefficient corresponding to various time zones, the electric energy [Wh] of various electric power can be further calculated. It can be calculated accurately.

  When the acquisition unit 11 does not acquire the first measurement value and the second measurement value, the calculation unit 12 calculates the electric energy [Wh] of various electric powers based on the charge/discharge command value [W] after being corrected by the correction coefficient. can do. For example, a charging power amount [Wh] corresponding to various services, a discharging power amount [Wh] corresponding to various services, a power amount [Wh] obtained by adding two or more of these, or any one of these It is possible to calculate the power amount [Wh] of any type of power such as the power amount [Wh] obtained by subtracting any of the above.

  According to the present embodiment described above, the same operational effects as those of the first embodiment can be realized. Further, according to the present embodiment, due to a failure of an arbitrary device (eg, PCS, storage battery) in the customer facility, the input/output of power from the PCS does not reach the integrated charge/discharge command value [W]. Even if it is, the power amount [Wh] of various powers can be accurately calculated by using the correction coefficient.

<Third Embodiment>
The power consumer facility of the present embodiment has a power generator. The power generation device is, for example, a device that generates power using natural energy (eg, sunlight, wind power, geothermal heat, etc.).

  FIG. 5 shows an example of the customer facility of this embodiment. As illustrated, the consumer facility of the example includes a photovoltaic power generation device (PV) as a power generation device. Moreover, the consumer facility of the said example has the measuring apparatus M3. The other configuration of the customer facility is the same as that of the first embodiment.

  As shown in the figure, PV is connected to the downstream side of the measuring device M1 and the upstream side of the measuring device M3, the PCS, the storage battery and the load.

  The measuring device M3 is connected to the downstream side of PV and upstream of the PCS, the storage battery, and the load, and the measured value [W] of the power flowing in one direction and the power flowing in the opposite direction at the connection point, and/or , The integrated value [Wh] of these is measured. The measurement device M3 is, for example, a smart meter or a measurement sensor.

  The processing device 10 of the present embodiment can acquire the measurement data of the measurement device M3 instead of the measurement data of the measurement device M1. Then, the processing device 10 can calculate the electric energy [Wh] of various electric powers based on the “measurement data of the measuring device M3” and the “at least one type of charge/discharge command value [W]”.

  Note that the processing device 10 may further acquire the measurement data of the measuring device M1. Then, the electric energy [Wh] of various electric powers is calculated based on the "measurement data of the measurement device M1", the "measurement data of the measurement device M3", and the "at least one type of charge/discharge command value [W]". May be.

  An example of a functional block diagram of the processing device 10 of the present embodiment is shown in FIG. 3 as in the first and second embodiments.

  The acquisition unit 11 acquires the measurement data measured by the measurement device M3. The acquisition unit 11 also acquires at least one type of charge/discharge command value [W]. The acquisition unit 11 may further acquire the measurement data measured by the measurement device M1.

  The calculation unit 12 calculates the electric energy [Wh] of various electric power based on the information acquired by the acquisition unit 11. For example, the calculation unit 12 may calculate the electric energy [Wh] of various electric powers based on the measurement data measured by the measuring device M3 and at least one type of charge/discharge command value [W].

  As an example, the calculating unit 12 in the configuration of FIG. 2 having no PV, based on the measurement data measured by the measuring device M1 and at least one type of charge/discharge command value [W], the electric energy of various electric powers. In the calculation method for calculating [Wh], the electric energy [Wh] of various kinds of electric power may be calculated by a calculation method in which the measurement data measured by the measurement device M1 is replaced with the measurement data measured by the measurement device M3.

  In addition, the calculation unit 12 may calculate the electric energy [Wh] of various electric powers based on the measurement data measured by the measurement device M1 and the measurement data measured by the measurement device M3. For example, the electric energy [Wh] of various electric power may be calculated by subtracting the other from one.

  According to the present embodiment described above, the same operational effects as those of the first embodiment can be realized. Further, according to this embodiment, the following operational effects can be obtained.

  When the configuration of the customer facility of the present embodiment (see FIG. 5) and the configuration of the customer facility described in the first embodiment (see FIG. 2) are compared, it is different whether or not PV exists. The presence of PV affects the measurement result of the measuring device M1. That is, even when the PCS, the storage battery, and the load shown in FIGS. 2 and 5 perform the same operation, the measurement data measured by each of the measuring devices M1 in FIGS. 2 and 5 differs depending on the PV operation. Becomes

  Therefore, the method of calculating the electric energy [Wh] of various electric powers based on the measurement data of the measuring device M1 and the at least one kind of charge/discharge command value [W] has a PV-free consumer facility and PV. It cannot be applied commonly to consumer equipment.

  The present embodiment has a configuration for eliminating the inconvenience by a simple means. Specifically, the customer facility having PV further includes a measuring device M3. Then, the processing device 10 acquires the measurement data from the measurement device M3 and calculates the electric energy [Wh] of various electric powers based on the measurement data.

  It will be apparent from a comparison between FIGS. 2 and 5, but when the PCS, the storage battery, and the load shown in FIGS. 2 and 5 operate in the same manner, they are measured by the measuring device M1 of FIG. 2 and the measuring device M3 of FIG. 5, respectively. The measurement data is the same regardless of the operation content of PV in FIG.

  Therefore, in the configuration shown in FIG. 2 which does not have PV, the electric energy [Wh] of various electric powers is calculated based on the measurement data of the measuring device M1 and at least one kind of charge/discharge command value [W], and PV is calculated. In the configuration shown in FIG. 5, which is configured to calculate the electric energy [Wh] of various electric powers based on the measurement data of the measuring device M3 and at least one type of charge/discharge command value [W], the PV It is possible to calculate various electric power amounts [Wh] with the same calculation method regardless of the presence or absence.

  Further, in the case of the configuration shown in FIG. 5 having both the measurement device M1 and the measurement device M3, the electric energy [Wh] of various electric powers should be calculated based on the measurement data of the measurement device M1 and the measurement data of the measurement device M3. You can Further, in the case of the configuration shown in FIG. 5, a more diverse amount of electric power [Wh] is calculated based on the measurement data of the measurement device M1, the measurement data of the measurement device M3, and at least one type of charge/discharge command value [W]. can do.

  FIG. 6 shows a modification of the customer facility of the present embodiment. The customer facility of the modification further includes a measuring device M2. The configuration of the measuring device M2 and the operational effects obtained thereby are as described in the second embodiment.

<First embodiment>
In this embodiment, the first charging/discharging command value [W] is a command value for charging/discharging for an electric power consumer. The first charge/discharge command value [W] is the charge/discharge command value [W] for the energy management service.

  The second charge/discharge command value [W] is a command value for charging/discharging for adjusting the supply and demand balance of the power system. That is, the second charge/discharge command value [W] is the charge/discharge command value [W] for the LFC control (ancillary service) and the GF control (ancillary service) described in the first embodiment. The charge/discharge command value [W] or both of them.

  In the case of the configuration of the first embodiment (see FIG. 2, FIG. 3, etc.), the calculation unit 12 of the processing device 10 uses the following calculation formula to calculate the amount of power to be charged by the power retailer to the power consumer. [Wh] is calculated.

(Power amount to be charged [Wh])=(First measured value [Wh] within a predetermined period)-(Second measured value [Wh] within a predetermined period)+(First measured value within a predetermined period) Integrated value [Wh] of discharge command value [W] in charge/discharge command value [W] of 2)-(charge command value [W in second charge/discharge command value [W] within a predetermined period) ] Integrated value [Wh])

  In the case of the configuration of the second embodiment (see FIG. 3, FIG. 4, etc.), the calculation unit 12 of the processing device 10 uses the following calculation formula to calculate the amount of power to be charged by the power retailer to the power consumer. [Wh] is calculated.

(Power amount to be charged [Wh])=(First measured value [Wh] within a predetermined period)-(Second measured value [Wh] within a predetermined period)+(First measured value within a predetermined period) The integrated value [Wh] of the corrected discharge command value [W] obtained by correcting the discharge command value [W] of the charge/discharge command value [W] of 2 with the correction coefficient)-(second value within a predetermined period) The integrated value [Wh] of the corrected charge command value [W] obtained by correcting the charge command value [W] of the charge command value [W] with the correction coefficient.

  In the case of the configuration of the third embodiment (see FIG. 3, FIG. 5, FIG. 6, etc.), the calculation unit 12 of the processing device 10 uses the above-described two calculation formulas (first measurement value [Wh within a predetermined period] [Wh ], and (the second measured value [Wh] within a predetermined period) are replaced with the measured data measured by the measuring device M3 shown in FIGS. Wh]) is calculated.

  Here, a process of deriving the above calculation formula will be described.

  First, the types of the first charge/discharge command value (x1) and the second charge/discharge command value (x2) (charge command value [W] or discharge command value [W]) and the magnitude relationship between x1 and x2 are determined. Based on this, the measurement values measured by the measuring device M2 shown in FIG. 4 can be classified into six states as shown in FIG.

  In FIG. 7, the values described in the columns corresponding to “x2” and “x1” are accompanied by the letters “h” and “j” and the numbers “1” to “6”. The numbers "1" to "6" indicate the serial numbers of the six states. The letters "h" and "j" indicate discharge and charge, respectively. That is, when "h" is added, it indicates that it is the discharge command value [W]. On the other hand, when "j" is attached, it indicates that it is the charge command value [W].

  In the column corresponding to "relationship between x2 and x1", conditions (relationship in magnitude between x2 and x1) for each state are shown. There are two states where no value is written in the relevant column. This means that if the types of x2 and x1 are written (both charge command value [W] or both discharge command value [W]), the state is classified regardless of the magnitude relationship. means.

  The column corresponding to “M2 measurement value” shows the measurement value measured by the measuring device M2 in each state. Here, it is assumed that the PCS inputs and outputs according to the integrated charge/discharge command value [W]. That is, the M2 measurement value indicates the integrated charge/discharge command value [W].

  The measurements represented using x1 and x2 and the letters "reverse" and "forward" are shown. The letters “reverse” and “forward” indicate the direction in which electric power flows. “Reverse” means that the value in the direction from the downstream side to the upstream side (discharge direction) is measured, and “forward” means that the value in the direction from the upstream side to the downstream side (charge direction) is measured. Show.

In the first state, both x1 and x2 are discharge command values [W]. In such a case, the measured value of M2 is in the illustrated state regardless of the magnitude relationship between x1 and x2.
In the second state, x1 is the charge command value [W] and x2 is the discharge command value [W]. And x1 is x2 or more. In such a case, the measured value of M2 is in the state shown in the figure.
In the third state, x1 is the charge command value [W] and x2 is the discharge command value [W]. And x2 is larger than x1. In such a case, the measured value of M2 is in the state shown in the figure.
In the fourth state, x1 is the discharge command value [W] and x2 is the charge command value [W]. And x2 is greater than or equal to x1. In such a case, the measured value of M2 is in the state shown in the figure.
In the fifth state, x1 is the discharge command value [W] and x2 is the charge command value [W]. And x1 is larger than x2. In such a case, the measured value of M2 is in the state shown in the figure.
In the sixth state, both x1 and x2 are charge command values [W]. In such a case, the measurement value of the measurement device M2 is in the illustrated state regardless of the magnitude relationship between x1 and x2.

  Here, the time at which each M2 measurement value is measured is indicated by the letter "t" and various subscripts. "" attached to t indicates that the M2 measurement value is a forward value, and "″" indicates that the M2 measurement value is a backward value.

Next, the first charge and discharge command value (x1), according to the second charge-discharge command value (x2) and the load power consumption (Y ₁ to Y _6), the six states as shown in FIG. 7 It can be classified into 9 states. The subscripts 1 to 6 of the power consumption Y correspond to the serial numbers in the above six states.

  In the column corresponding to the "relationship between x2, x1 and Y", the conditions (relationship between M2 measured value and Y) for each state are shown. Note that the subdivision conditions are shown only for the subdivided states among the above six states.

  The column corresponding to "M1 measured value" shows the measured value measured by the measuring device M1 in each of the nine states. Here, it is assumed that the PCS inputs and outputs according to the integrated charge/discharge command value [W].

  The measured values expressed using x1, x2 and Y and the letters "reverse" and "forward" are shown. The letters “reverse” and “forward” indicate the direction in which electric power flows. “Inverse” indicates that the value in the direction from the downstream side to the upstream side is measured, and “forward” indicates that the value in the direction from the upstream side to the downstream side is measured.

  Here, the time when each M1 measurement value is measured is indicated by the letter “t” and various subscripts. "" attached to t indicates that the M1 measurement value is a forward value, and "″" indicates that the M1 measurement value is a backward value.

  In this way, the electric power can be classified according to the types of x1 and x2 (charge or discharge), the magnitude relationship between x1 and x2, the magnitude relationship between the M2 measurement value and Y, and the like.

  Next, using the relationship of FIG. 7, the electric power to be charged by the electric power retailer to the electric power consumer will be considered. The electric power retailer does not charge the electric power supplied to the electric power consumer equipment for adjusting the supply and demand balance of the electric power system, and does not charge the electric power consumer for the electric power consumer (for purposes other than adjusting the supply and demand balance of the electric power system). The electricity supplied to the equipment is charged.

First, consider the time period for discharging in the energy management service. During the time period, the power consumption Y of the load (any one of Y _{1 to} Y ₆ ) is offset, and therefore the storage battery is discharged (x1 _h1 , x1 _h4, and x1 _h5 ). Of the power consumption Y of the load (any one of Y _{1 to} Y ₆ ) that is offset by the discharge from the storage battery is not charged.

However, the upper limits of x1 _h1 , x1 _h4, and x1 _h5 are determined by the output upper limit for the energy management service, the rated output of the PCS, and the like. When Y exceeds the upper limit, the amount that cannot be offset by the discharge by the storage battery occurs. The electric power consumer receives the amount δY that cannot be offset (the amount obtained by subtracting x1 _h1 from Y _{1, the amount obtained} by subtracting x1 _h4 from Y ₄ or the _{amount obtained} by subtracting x1 _h5 from Y ₅ ) from the power grid. Will be done. Then, the electric power retailer charges this portion.

Next, consider the time period for charging with the energy management service. During the time period, the power consumer receives from the power grid both the amount of charging the storage battery (x1 _j2 , x1 _j3, and x1 _j6 ) and the power consumption Y of the load. That is, the power consumer receives ΔY (the total of Y ₂ and x1 _j2 , the total of Y ₃ and x1 _j3, and the total of Y ₆ and x1 _j6 ) from the power grid. Then, the electric power retailer charges this portion.

  FIG. 8 shows the above relational expression. Then, FIG. 9 shows a table obtained by partially replacing the table of FIG. 7 with the equation of FIG.

Here, the integrated value M1 (forward) _Z of the M1 measured value [W] at the timing when the M1 measured value in FIG. 9 is in the forward direction during the Z time is expressed by the equation (15-1) in FIG. Be done. Similarly, the integrated value M1 (reverse) _Z of the M1 measurement value [W] at the timing when the M1 measurement value in FIG. 9 is in the opposite direction during the Z time is expressed by the equation (15-2) in FIG. Be done. Note that some of the expressions are simplified in the relationship shown in FIG. 11 (the same applies hereinafter).

Here, it can be seen from the table of FIG. 9 that the time width in which t ₂₂ ′ appears and the time width in which t ₁₂ ′ appears are equal. Similarly, it can be seen that the time width in which t ₂₄ ′ appears and the time width in which t ₁₄ ′ appears are equal. Similarly, it can be seen that the time width in which t ₂₆ ′ appears and the time width in which t ₁₆ ′ appears are equal.

Further, as described above, x1 _h1 , x1 _h4, and x1 _h5 are for canceling the power consumption Y of the load. Therefore, x1 _h1 , x1 _h4, and x1 _h5 are less than or equal to the power consumption Y of the load. Further, it is preferable that x1 _h1 , x1 _h4, and x1 _{h5 be} slightly smaller than the power consumption Y in order to suppress reverse power flow to the power system. In such a case, x1 _h1 , x1 _h4, and x1 _h5 are smaller than the power consumption Y. In such a case, the state of t _{15 ″} shown in FIG. 9 does not occur. Therefore, similarly to the above, it is understood that the time width in which t ₂₅ ′ appears and the time width in which t ₁₅ ′ appears are equal.

Based on this relationship, when t ₁₂ ′, t ₁₄ ′, t ₁₅ ′, and t ₁₆ ′ of the formula (15-1) are replaced, the formula (15-3) is obtained.

  Expression (15-3) can be transformed into Expression (15-4). The underlined term in Expression (15-4) indicates the charging target. Further, the equation (15-2) can be transformed into the equation (15-5). Then, in the expression (15-5), the sign of the underlined item is reversed to indicate the charging target.

  The term underlined in equation (15-4) and the underlined term in equation (15-5) with their signs reversed is calculated as "order in which electricity retailer should charge. The electric energy of the power flow component" is shown by the equation in FIG.

Meanwhile, from Table _9, 'time width _{appears, t 11' t 21} and _{t 11} becomes It can be seen equal to either appears duration of''. Similarly, it can be seen that the time width in which t ₂₃ ′ appears and the time width in which either t ₃₁ ′ or t _{13 ″} appears are equal.

  When the formula is transformed based on the relationship as shown in FIG. 12, the formula shown at the bottom of FIG. 12 is obtained. An extracted version of the formula shown at the bottom of FIG. 12 is shown in FIG.

  The first term of the equation is an integral value (first measured value) of the forward power measured by the measuring device M1 during the Z time. The second term of the equation is an integrated value (second measured value) of the electric power in the reverse direction measured by the measuring device M1 during the Z time.

The third term of the equation is the discharge electric energy (Wh) for ancillary service measured by the measuring device M2, and the second charge/discharge command value [W] of x2 _h1 , x2 _h2, and x2 _h3, respectively. Can be calculated by integrating and adding them. The fourth term of the equation is the charge power amount (Wh) for the ancillary service measured by the measuring device M2, and the second charge/discharge command value [W] of x2 _j4 , x2 _j5, and x2 _j6, respectively. Can be calculated by integrating and adding them.

  From the above, the calculation formula corresponding to the configuration of the first embodiment was obtained. Next, a process of deriving a calculation formula corresponding to the second embodiment will be described.

Inverse) _Z is shown as in FIG. 16 from the table in FIG.

In this embodiment, the correction coefficient A is calculated based on the formula of FIG. 17 obtained from the formula of FIG. Then, the calculation formula corresponding to the second embodiment is derived as shown in FIG. 18 using FIG. 13 and the correction coefficient A. That is, based on the value _obtained by correcting the second charge/discharge command value [W] (x2 _h1 , x2 _h2 , x2 _h3 , x2 _j4 , x2 _j5 and x2 _j6 ) with the correction coefficient A, the chargeable power amount [Wh] To calculate.

Note that the calculation formulas corresponding to the configuration of the third embodiment are M3 (forward) _Z and M3 (reverse) for M1 (forward) _Z and M1 (reverse) _Z in the calculation formulas of FIGS. 13 and 18, respectively. Obtained by substituting _Z. M3 (forward) _Z is the integrated value of the forward power measured by the measuring device M3 (see FIGS. 5 and 6) during the Z time. M3 (reverse) _Z is the integrated value of the electric power in the reverse direction measured by the measuring device M3 (see FIGS. 5 and 6) during the Z time.

The integrated value [Wh] of the charging command value [W] in W] may be calculated.

  In the case of the configuration of the second embodiment, these values can be calculated using the second charge/discharge command value [W] and the correction coefficient. That is, the calculation unit 12 calculates the integrated value [Wh] of the corrected discharge command value obtained by correcting the discharge command value [W] of the second charge/discharge command value [W] within the predetermined period with the correction coefficient, It is only necessary to calculate the integrated value [Wh] of the corrected charge command value obtained by correcting the charge command value [W] of the second charge/discharge command value [W] within the predetermined period with the correction coefficient.

Further, the calculation unit 12 calculates an integrated value of each of the various second charge/discharge command values [W] (x2 _h1 , x2 _h2 , x2 _h3 , x2 _j4 , x2 _j5 and x2 _j6 ) within a predetermined period, or By calculating an integrated value of values obtained by correcting the various second charge/discharge command values [W] with the correction coefficient A, it is possible to calculate the electric energy [Wh] of various electric power.

Similarly, the calculation unit 12 calculates the integrated value of each of the various first charge/discharge command values [W] (x1 _h1 , x1 _j2 , x1 _j3 , x1 _h4 , x1 _h5 and x1 _j6 ) within a predetermined period. By calculating the integrated value of the values obtained by correcting the various first charge/discharge command values [W] with the correction coefficient A, the electric energy [Wh] of various electric powers can be calculated.

  In addition, the calculation unit 12 calculates based on one or a plurality of integrated values calculated based on one or a plurality of types of discharge command values [W] and one or a plurality of types of charge command values [W]. The electric energy [Wh] of various electric powers can be calculated by a predetermined calculation by using two or more integrated values among the one or more integrated values thus obtained.
