Furthermore, ⁇ (cumulative load power consumption) ⁇ N / (n ⁇ 1) ⁇ in equation (1) assumes that the past average power consumption of the load 122 is equal to the future average power consumption. It is the value which estimated the power consumption in the control period. That is, the estimated imbalance amount is an estimate of the imbalance amount at the time when the control period of 30 minutes has expired. For example, in the example of FIG.
- the “power consumption” in the power distribution system 50 is a total value of the power consumed by the load 122 and the power charged by the storage battery 142 (a negative value in the case of discharging). That is, ⁇ total charge / discharge energy ⁇ + ⁇ (total load power consumption) ⁇ N / (n ⁇ 1) ⁇ means an estimated value of “power consumption” in the power distribution system 50.
- the power adjustment device 200 determines whether or not the absolute value of the estimated imbalance amount exceeds a predetermined threshold Th (step S106). Specifically, the estimated imbalance amount determination unit 218 of the power adjustment apparatus 200 compares the absolute value of the estimated imbalance amount calculated by the imbalance amount estimation unit 216 in S105 with the threshold Th. Then, the estimated imbalance amount determination unit 218 determines whether or not the absolute value of the estimated imbalance amount is larger than the threshold value Th.
- the threshold Th is determined, for example, so as to suppress the payment of the out-of-variable generation charge.
- the threshold value Th may be a value [Wh] that is equal to or less than half of 3% of the contract power.
- the threshold Th may be a value [Wh] that is 3% or less of the planned value of the generated power obtained in S101. If the absolute value of the estimated imbalance amount exceeds the threshold Th, the process proceeds to S107, and if not, the process proceeds to S110.
- the power adjustment device 200 calculates the charge / discharge power amount of the storage battery 142 (step S107). Specifically, the charge / discharge power amount calculation unit 220 of the power adjustment device 200 calculates the charge / discharge power amount that the storage battery 142 should charge or discharge in the nth time slot. More specifically, the charge / discharge power amount calculation unit 220 calculates the charge / discharge power amount using the following equation (2).
- ⁇ estimated imbalance amount ⁇ is the estimated imbalance amount calculated by the imbalance amount estimation unit 216 in S105. Further, (N ⁇ n + 1) is the number of remaining time slots in the current control period. That is, (N ⁇ n + 1) indicates the remaining time until the end of the current control period.
- the charge / discharge power amount shows a positive value (that is, when it is estimated that the supply is excessive), it corresponds to the power amount that the storage battery 142 should charge during the nth time slot.
- the charge / discharge power amount shows a negative value (that is, when it is estimated that supply is insufficient)
- the charge / discharge power amount corresponds to the power amount that the storage battery 142 should discharge during the nth time slot.
- the power adjustment device 200 issues a charge / discharge instruction to the power storage system 140 (step S108). Specifically, the charge / discharge instruction unit 222 of the power adjustment apparatus 200 generates a charge / discharge instruction indicating the charge / discharge power amount calculated by the charge / discharge power amount calculation unit 220 in S107. Then, the charge / discharge instruction unit 222 transmits a charge / discharge instruction to the control device 144 of the power storage system 140 via the communication network 60.
- the charge / discharge instruction unit 222 causes the storage battery 142 to charge the power amount according to the charge / discharge power amount during the nth time slot. To instruct.
- the charge / discharge instruction unit 222 discharges the power amount according to the charge / discharge power amount during the nth time slot. To instruct.
- the control device 144 of the power storage system 140 controls the storage battery 142 to charge or discharge according to the received charge / discharge instruction.
- the storage battery 142 charges the electric energy according to the estimated imbalance amount during the n-th time slot when the supply is excessive.
- the storage battery 142 discharges the amount of power corresponding to the estimated imbalance amount during the nth time slot.
- the power adjustment device 200 updates the accumulated charge / discharge power amount (step S109). Specifically, the power amount storage unit 210 of the power adjustment apparatus 200 sets the charge / discharge power amount calculated in S107 to the accumulated value of the charge / discharge power amount stored before the process in the nth time slot. to add. As a result, the total amount of charge / discharge power stored in the power storage unit 210 is updated.
- the power adjustment apparatus 200 adds 1 to n (step S110). That is, the power adjustment apparatus 200 increments the number n of the time slot to be processed by one. Then, the power adjustment apparatus 200 determines whether the time slot number n exceeds the number N of time slots (step S111). If n is greater than N (YES in S111), the process has been completed for all time slots in the current control period, so the process returns to S100 and proceeds to the process in the next control period. On the other hand, if n is equal to or smaller than N (NO in S111), the process returns to S103 and proceeds to the process for the next time slot in the current control period.
- power adjustment device 200 calculates an estimated imbalance amount in the current control period, and calculates charge / discharge power amount according to the estimated imbalance amount and the remaining time of the control period. ing. That is, the calculated charge / discharge power amount has a smaller ratio to the estimated imbalance amount when the remaining time is long. This is because the longer the remaining time, the longer the time can be used for power adjustment, and the charge / discharge power amount in each time slot may be smaller than the estimated imbalance amount. Thereby, in the control period, it is suppressed that the storage battery 142 charges / discharges only in a certain time interval (for example, at the end of the control period).
- the power adjustment device 200 can adjust the supply and demand of power at an appropriate timing using the storage battery 142.
- the power adjustment device 200 is configured to issue a charge / discharge instruction when the estimated imbalance amount exceeds the threshold Th. Thereby, when the estimated imbalance amount is small, the charge / discharge instruction is not performed. Therefore, in the present embodiment, it is possible to suppress the charge / discharge frequency of the storage battery 142. Thereby, it becomes possible to prevent deterioration of the storage battery 142.
- the power adjustment apparatus 200 calculates the estimated imbalance amount using the above equation (1). That is, in the present embodiment, the estimated imbalance amount is calculated as a difference between the planned value of the generated power amount and the sum of the accumulated charge / discharge energy amount and the predicted value of the load power amount (power consumption amount). Is done. Thereby, the estimated imbalance amount decreases as time elapses (that is, as the end of the control period is approached). Therefore, it is possible to suppress the difference between the generated power amount and the consumed power amount during the control period. Furthermore, this makes it possible to control power adjustment to achieve the same amount at the same time.
- the estimated imbalance amount is calculated for each time slot, and a charge / discharge instruction is issued for each time slot.
- the frequency of processing can be adjusted by adjusting the time slot interval. For example, since the frequency of processing increases by shortening the time interval of the time slot, it is possible to further suppress the difference between the power generation amount and the power consumption amount during the control period.
- the frequency of processing is suppressed by increasing the time interval of the time slot, it is possible to suppress the load of resources (including communication resources) of the power adjustment apparatus 200.
