Modes for Carrying Out the Invention

[0010] Hereinafter, a power suppression distribution amount calculation device and a power suppression distribution amount calculation method according to embodiments of the present disclosure will be described with reference to the drawings. Such embodiments show one aspect of the present disclosure, do not limit this disclosure, and can be arbitrarily changed within the scope of the technical idea of this disclosure.

[0011] FIG. 1 is a schematic configuration diagram showing the configuration of a demand response system 100 according to an embodiment. The demand response system 100 formulates a plan to suppress power of a specific magnitude during a specific future period.

[0012] As shown in FIG. 1, the demand response system 100 includes a general power transmission and distribution utility 102, an aggregator 104, and a community 106 which is an aggregate of a plurality of consumers 108.

[0013] Before the time period when power supply and demand is predicted to be tight (hereinafter referred to as the DR time period) arrives, the general power transmission and distribution operator 102 requests the aggregator 104 to suppress power during the DR time period. The DR time period is composed of one time period or a plurality of consecutive time periods. The general power transmission and distribution operator 102 determines whether the power request is achieved for each time period. When receiving the DR request from the general power transmission and distribution operator 102, the aggregator 104 distributes the amount of power to be suppressed to achieve this DR request to each of the plurality of consumers 108. The consumers 108 are, for example, factories, commercial facilities, residences, etc.

[0014] In the form illustrated in FIG. 1, the aggregator 104 is provided with a power suppression distribution amount calculation device 1 that calculates the distribution amount for each of the plurality of consumers 108 with respect to the amount of power suppression during the DR time period. The power suppression distribution amount calculation device 1 is a cloud server provided in a cloud environment and includes a processor such as a CPU or GPU (not shown) and a memory such as a ROM or RAM. The power suppression distribution amount calculation device 1 realizes each functional unit included in the power suppression distribution amount calculation device 1 by the processor operating (performing calculations, etc.) according to the instructions of the program loaded into the memory. Hereinafter, each functional unit of the power suppression distribution amount calculation device 1 will be described. Note that the power suppression distribution amount calculation device 1 is not limited to a cloud server and may be, for example, a computer arranged within the facilities of the aggregator 104.

[0015] <First Embodiment> (Configuration) FIG. 2 is a schematic functional block diagram of the power suppression distribution amount calculation device 1 according to the first embodiment. In the first embodiment, the DR time period includes the first time period, and the start time of the first time period is the same as the start time of the DR time period. Before the first time period arrives, the general power transmission and distribution operator 102 requests the aggregator 104 to suppress power during the first time period. Note that in the first embodiment, the start time of the first time period is the same as the start time of the DR time period, but the present disclosure is not limited to this form.

[0016] As shown in FIG. 2, the power suppression distribution amount calculation device 1 includes a suppression amount calculation unit 2, a distribution amount calculation unit 4, a device state collection unit 6, a determination unit 8, and a distribution amount correction unit 10.

[0017] When the suppression amount calculation unit 2 receives a DR request from the general power transmission and distribution utility 102, it calculates the power suppression amount for the entire community 106 in the first time period. This suppression amount is preferably equal to or greater than the amount of power that can achieve the DR request of the general power transmission and distribution utility 102, but it may also be less than the amount of power that can achieve the DR request of the general power transmission and distribution utility 102.

[0018] Before the first time period, the distribution amount calculation unit 4 calculates the distribution amount for each of the plurality of consumers 108 with respect to the suppression amount. In other words, before the first time period arrives, the distribution amount calculation unit 4 formulates a distribution plan P for achieving the power suppression in the first time period. The method for formulating the distribution plan P for the first time period by the distribution amount calculation unit 4 is not particularly limited. For example, the distribution amount calculation unit 4 calculates the distribution amount to be requested from this consumer 108 based on the actual record of the power suppression amount of the consumer 108 for the DR request before the first time period. In some embodiments, the distribution amount calculation unit 4 calculates the distribution amount in consideration of the device state information X of the power device 110 of the consumer 108 collected by the device state collection unit 6 described later.

[0019] The device state collection unit 6 is configured to be able to collect device state information X regarding the states of the power devices 110 for each of the plurality of consumers 108 in real time. For example, the power suppression distribution amount calculation device 1 is electrically connected to the power devices 110 for each of the plurality of consumers 108, and the device state collection unit 6 of the power suppression distribution amount calculation device 1 collects the device state information X in real time by receiving the electrical signals transmitted from the power devices 110. Note that the power suppression distribution amount calculation device 1 may be wirelessly connected to the power device 110, or may be wired-connected by a dedicated line or a power line.

[0020] Specifically describe the equipment status information X of the power equipment 110. FIG. 3 is a diagram for explaining the equipment status information X of the power equipment 110 according to several embodiments. The power equipment 110 includes a power consumption equipment 112 and a power generation equipment 114. The power consumption equipment 112 is equipment that consumes the power transmitted and distributed by the general power transmission and distribution operator 102, such as a refrigerator or a boiler installed in a factory, a lighting device or an air conditioner installed in a commercial facility or a residence. The power generation equipment 114 is equipment that generates power by itself, such as a generator or a storage battery driven by city gas, LNG, light oil, or heavy oil as fuel.

[0021] In the form illustrated in FIG. 3, the power equipment 110 has both the power consumption equipment 112 and the power generation equipment 114. The equipment status information X includes the received power amount X1 received by the power consumption equipment 112 of the power equipment 110 and the generated power amount X2 generated by the power generation equipment 114 of the power equipment 110. The received power amount X1 is, for example, a value measured by the power meter 116 for the power W transmitted and distributed from the general power transmission and distribution operator 102 to the power consumption equipment 112. The power meter 116 is configured to transmit the received power amount X1 to the equipment status collection unit 6 via, for example, the Internet. The generated power amount X2 is, for example, a value calculated from the operation information Y (number of units, operation rate, etc.) of the power generation equipment 114 by the power generation amount calculation device 118. The power generation amount calculation device 118 is configured to transmit the generated power amount X2 to the equipment status collection unit 6 via, for example, the Internet. According to the form illustrated in FIG. 3, since the equipment status collection unit 6 collects the received power amount X1 from the power meter 116 and the generated power amount X2 from the power generation amount calculation device 118, the excess or deficiency state of the power of the consumer 108 can be quickly collected.

[0022] In addition, in another embodiment, the power equipment 110 has the power consumption equipment 112 but does not have the power generation equipment 114, and the equipment status information X includes only the received power amount X1. In another embodiment, the power equipment 110 has both the power consumption equipment 112 and the power generation equipment 114, but the equipment status information X includes only the generated power amount X2.

[0023] Returning to FIG. 2, the determination unit 8 and the allocation amount correction unit 10 will be described. The determination unit 8 determines whether to correct the allocation amounts for each of the plurality of consumers 108 calculated by the allocation amount calculation unit 4 based on the device state information X collected in real time by the device state collection unit 6 in the first time period. In other words, the determination unit 8 determines whether to correct the allocation plan P for the first time period formulated by the allocation amount calculation unit 4 based on the device state information X collected in real time by the device state collection unit 6 in the first time period.

[0024] Here, an example of the determination method by the determination unit 8 will be described. First, the determination unit 8 calculates the average power reception amount of the community 106 per unit time (for example, per minute) in the first time period. Specifically, the determination unit 8 calculates the total power received by the entire community 106 from the start time of the first time period until the elapsed time has elapsed based on the device state information X collected until the elapsed time has elapsed since the start time of the first time period. Then, the determination unit 8 calculates the average power reception amount by dividing this power amount by the elapsed time. When at least one consumer 108 has a power generation device 114, the average power reception amount is calculated by dividing the value obtained by subtracting the power generated from the total power received by the entire community 106 from the start time of the first time period until the elapsed time has elapsed by the elapsed time. Note that the time when the elapsed time has elapsed since the start time of the first time period does not exceed the end time of the first time period.

[0025] In some embodiments, when the time when the elapsed time has elapsed since the start time of the first time period is taken as the elapsed time, the average power reception amount is the average value per unit time of the total power received by the entire community 106 from just before the elapsed time to the elapsed time. Just before the elapsed time means a time that is a preset time in the past from the elapsed time, for example, 2 minutes before the elapsed time. According to such a configuration, the determination unit 8 can determine whether to correct the allocation plan P for the first time period by considering only the state closest to the latest state of the power device 110 of the consumer 108.

[0026] Next, the determination unit 8 calculates the average target power reception amount of the power supplied to the community 106 per unit time in the first time period. Specifically, the determination unit 8 divides the value obtained by subtracting the suppression amount from the predicted value (baseline) of the power consumed in the first time period when there is no DR request by the length of the first time period to calculate the average target power reception amount. And if the average target power reception amount < the average power reception amount, the determination unit 8 determines to correct the distribution plan P for the first time period. On the other hand, if the average target power reception amount > the average power reception amount, the determination unit 8 determines not to correct the distribution plan P for the first time period. In some embodiments, if the average target power reception amount < the average power reception amount × α (α is a value less than 1), the determination unit 8 determines to correct the distribution plan P for the first time period. α is, for example, a value of 0.8 or more. Note that the length of the first time period is the time elapsed from the start time to the end time of the first time period, and is, for example, 30 minutes.

[0027] When the determination unit 8 determines to correct the distribution amount for each of the plurality of consumers 108, the distribution amount correction unit 10 corrects the distribution amount for each of the plurality of consumers 108. In other words, when the determination unit 8 determines to correct the distribution plan P for the first time period, the distribution amount correction unit 10 corrects the distribution plan P for the first time period. And the corrected distribution amounts for each of the plurality of consumers 108 are output to the outside of the power suppression distribution amount calculation device 1 and are notified to the consumers 108 corresponding to these distribution amounts. When the determination unit 8 determines not to correct the distribution plan P for the first time period, the distribution plan P for the first time period is output to the outside of the power suppression distribution amount calculation device 1 without being corrected by the distribution amount correction unit 10.

[0028] Here, an example of the correction method by the distribution amount correction unit 10 will be described. Based on the device state information X collected in real time by the device state collection unit 6, the distribution amount correction unit 10 selects a first consumer 108A among the plurality of consumers 108 for which it is predicted that it is difficult to suppress the power to meet the previously notified distribution amount, and a second consumer 108B excluding the first consumer 108A. Then, the distribution amount correction unit 10 decreases the distribution amount to be redistributed to the first consumer 108A and increases the distribution amount to be distributed to the second consumer 108B by this decreased distribution amount.

[0029] Further, the distribution amount correction unit 10 may be configured to re-correct the distribution amount corrected by the distribution amount correction unit 10 in the first time period. In some embodiments, the determination unit 8 determines, in the first time period, whether to re-correct the distribution amount for each of a plurality of consumers 108 corrected by the distribution amount correction unit 10 based on the device state information X collected in real time by the device state collection unit 6. When the determination unit 8 determines to re-correct, the distribution amount correction unit 10 re-corrects the distribution amount for each of the plurality of consumers 108.

[0030] (Function and Effect) According to the first embodiment, for the distribution plan P in the first time period, whether correction is necessary is determined based on the device state information X collected in real time in the first time period. That is, whether correction is necessary for the distribution plan P in the first time period is determined in consideration of the state of the power device 110 in the first time period. When the determination unit 8 determines to correct the distribution plan P in the first time period, the distribution amount correction unit 10 corrects the distribution plan P in the first time period. Therefore, the accuracy of the distribution plan P in the first time period can be improved, and the possibility of achieving the DR request can be increased.

[0031] The determination unit 8 according to some embodiments will be described. FIG. 4 is a diagram showing the state of the determination unit 8 according to some embodiments. In FIG. 4, the first time t1 is the start time of the first time period. The second time t2 is the time when the first time Δ1 has elapsed from the first time t1. The third time t3 is the time when the distribution amount correction unit 10 corrects the distribution amount (the time when the distribution plan P in the first time period is corrected). The fourth time t4 is the time when the second time Δ2 has elapsed from the third time t3. The fifth time t5 is the end time of the first time period.

[0032] The state of the determination unit 8 includes a first state s1 that determines whether to correct the distribution plan P for the first time period based on the device state information X collected in real time in the first time period, and a second state s2 that determines not to correct the distribution plan P for the first time period regardless of the device state information X collected in real time. The first time period Δ1 is a time required to accumulate the device state information X necessary to make the determination of the determination unit 8 accurate to a certain level or more, and is predetermined. The second time period Δ2 is a time required for the consumer 108 to respond to the corrected distribution plan P for the first time period, and is predetermined. The second time period Δ2 is, for example, the time from when the distribution amount is notified to the consumer 108 until the generated power amount generated by the power generation device 114 of the consumer 108 reaches the target value (the generated power amount capable of achieving the DR request).

[0033] As shown in FIG. 4, in some embodiments, the state of the determination unit 8 is in the second state s2 from the first time t1 to the second time t2. That is, the determination unit 8 determines not to correct the distribution amount (distribution plan P for the first time period) until the first time period Δ1 elapses from the start time of the first time period.

[0034] Until the first time period Δ1 elapses from the start time of the first time period, the device state information X collected by the device state collection unit 6 is not sufficient, so the accuracy of the determination of the determination unit 8 is low, and it is not necessary to correct the distribution plan P for the first time period. According to the configuration illustrated in FIG. 4, it is possible to suppress the correction of the distribution plan P for the first time period until the device state information X is sufficiently collected and the accuracy of the determination of the determination unit 8 is increased.

[0035] As shown in FIG. 4, in some embodiments, the state of the determination unit 8 is in the second state from the third time t3 to the fourth time t4. That is, in the first time period, when the distribution amount correction unit 10 corrects the distribution amount (distribution plan P for the first time period), the determination unit 8 determines not to correct the distribution amount until the second time period Δ2 elapses from the time when the distribution amount correction unit 10 corrects the distribution amount.

[0036] It takes some time for the consumer 108 to respond to the corrected allocation plan P for the first time period. Therefore, until some time has elapsed since the time when the allocation plan P for the first time period was corrected, the device status information X collected by the device status collection unit 6 is not sufficient, so the accuracy of the determination by the determination unit 8 is low, and the correction of the allocation plan P for the first time period is unnecessary. According to the configuration illustrated in FIG. 4, after the consumer 108 responds to the corrected allocation plan P for the first time period, the device status information X is sufficiently collected, and the correction of the allocation plan P for the first time period can be suppressed until the accuracy of the determination by the determination unit 8 becomes high.

[0037] In the form illustrated in FIG. 4, in the time period of the first time period excluding the time period from the first time t1 to the second time t2 and from the third time t3 to the fourth time t4, the state of the determination unit 8 is the first state s1. In other words, the state of the determination unit 8 is the first state s1 both from the second time t2 to the third time t3 and from the fourth time t4 to the fifth time t5. According to such a configuration, the time during which the state of the determination unit 8 is the first state s1 is increased, and even if an unintended event occurs in the first time period, the allocation plan P for the first time period that takes this unintended event into consideration can be promptly formulated.

[0038] <Second Embodiment> The power suppression allocation amount calculation device 1 according to the second embodiment of the present disclosure will be described. The second embodiment is obtained by adding the functions of the suppression amount calculation unit 2, the allocation amount calculation unit 4, and the allocation amount correction unit 10. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the detailed description thereof is omitted.

[0039] (Configuration) FIG. 5 is a schematic functional block diagram of the power suppression allocation amount calculation device 1 according to the second embodiment. In the second embodiment, the DR time period includes a first time period and a second time period that is continuous with the first time period and comes after the first time period. Before the arrival of the first time period, the general power transmission and distribution utility 102 requests the aggregator 104 to suppress power in the first time period and suppress power in the second time period. That is, the DR request according to the second embodiment includes both suppression of power in the first time period and suppression of power in the second time period. As shown in FIG. 2, in addition to the distribution plan P for the first time period, the power suppression allocation amount calculation device 1 also calculates a second distribution plan P2 for the second time period, which is the allocation amount for each of the plurality of consumers 108 with respect to the amount of power suppression in the second time period.

[0040] When receiving the DR request, the suppression amount calculation unit 2 calculates the amount of power suppression for the entire community 106 in the first time period (the first suppression amount) and the amount of power suppression for the entire community 106 in the second time period (the second suppression amount). The first suppression amount and the second suppression amount may be different from each other or may be equal to each other.

[0041] Before the first time period, the allocation amount calculation unit 4 calculates the allocation amount for each of the plurality of consumers 108 with respect to the first suppression amount (the first allocation amount) and the allocation amount for each of the plurality of consumers 108 with respect to the second suppression amount (the second allocation amount). The first allocation amount corresponds to the distribution plan P for the first time period described above, and the second allocation amount corresponds to the second distribution plan P2 for the second time period described above.

[0042] In the first time period, when the determination unit 8 determines to correct the first allocation amount, the allocation amount correction unit 10 corrects the second allocation amount before the second time period. Then, the corrected second allocation amount is output outside the power suppression allocation amount calculation device 1 and is notified to the consumer 108 corresponding to this second allocation amount before the second time period. In the first time period, when the determination unit 8 determines not to correct the first allocation amount, the second allocation amount is output outside the power suppression allocation amount calculation device 1 without being corrected by the allocation amount correction unit 10.

[0043] (Function and Effect) In the first time period, when the determination unit 8 determines that the first distribution amount needs to be corrected, it is highly likely that the second distribution amount also needs to be corrected. This is because, for example, when an unexpected event (e.g., a failure) occurs in the power equipment 110 of the consumer 108 in the first time period, it is highly likely to affect the suppression of the power of the consumer 108 in the second time period.

[0044] According to the second embodiment, when the determination unit 8 determines that the first distribution amount needs to be corrected in the first time period, the distribution amount correction unit 10 corrects the second distribution amount. Therefore, it is possible to improve the accuracy of the second distribution amount and increase the possibility of achieving the DR request before the second time period.

[0045] <Power Suppression Distribution Amount Calculation Method> FIG. 6 is a flowchart of a power suppression distribution amount calculation method according to an embodiment. As shown in FIG. 6, the power suppression distribution amount calculation method includes a suppression amount calculation step S2, a distribution amount calculation step S4, a distribution amount notification step S6, a collection step S8, a determination step S10, and a correction step S12.

[0046] In the suppression amount calculation step S2, the power suppression amount for the entire community 106 in the first time period is calculated.

[0047] In the distribution amount calculation step S4, before the first time period, the distribution amount for each of the plurality of consumers 108 with respect to the suppression amount calculated in the suppression amount calculation step S2 is calculated. That is, in the distribution amount calculation step S4, the distribution plan P for the first time period is formulated.

[0048] In the distribution amount notification step S6, the distribution amount for each of the plurality of consumers 108 calculated in the distribution amount calculation step S4 is notified to the corresponding consumer 108 before the first time period.

[0049] In the collection step S8, in the first time period, the device state information X regarding the state of the power equipment 110 for each of the plurality of consumers 108 is collected in real time.

[0050] In the determination step S10, in the first time period, it is determined whether to correct the distribution plan P for the first time period based on the device status information X collected in real time in the collection step S8. If it is determined to correct the distribution plan P for the first time period (S10: Yes), the process proceeds to the correction step S12. If it is determined not to correct the distribution plan P for the first time period (S10: No), the process returns to the collection step S8.

[0051] In the correction step S12, when it is determined in the determination step S10 to correct the distribution plan P for the first time period, the distribution plan P for the first time period is corrected. Then, when the correction of the distribution plan P for the first time period is completed, the process returns from the correction step S12 to the distribution amount notification step S6. In the distribution amount notification step S6, in the first time period, the distribution plan P for the first time period corrected in the correction step S12 is notified to the consumer 108.

[0052] According to such a method for calculating the power suppression distribution amount, the determination of whether to correct the distribution plan P for the first time period takes into account the state of the power device 110 in the first time period. And when it is determined to correct the distribution plan P for the first time period, the corrected distribution plan P for the first time period is notified to the consumer 108. Therefore, the accuracy of the distribution plan P for the first time period can be improved, and the possibility of achieving the DR request can be increased.

[0053] In some embodiments, the suppression amount calculation step S2 calculates the power suppression amount for the entire community 106 in the first time period (the first suppression amount) and the power suppression amount for the entire community 106 in the second time period (the second suppression amount). The distribution amount calculation step S4 calculates, before the first time period, the distribution amount for each of the plurality of consumers 108 with respect to the first suppression amount (the first distribution amount) and the distribution amount for each of the plurality of consumers 108 with respect to the second suppression amount (the second distribution amount). The correction step S12 corrects the second distribution amount before the second time period when it is determined to correct the first distribution amount in the first time period. And the distribution amount notification step S6 notifies the consumer 108 of the second distribution amount corrected in the correction step S12 in the first time period.

[0054] According to such a method for calculating the power suppression distribution amount, in the first time period, if it is determined to correct the first distribution amount, the second distribution amount is corrected, and the corrected second distribution amount is notified to the consumer 108. Therefore, before the second time period, it is possible to improve the accuracy of the second distribution amount and increase the possibility of achieving the DR request.

[0055] The content described in each of the above embodiments is understood as follows, for example.

[0056] [1] The power suppression distribution amount calculation device (1) according to the present disclosure is a suppression amount calculation unit (2) that calculates a suppression amount of power for the entire community (106) that is an aggregate of a plurality of consumers (108) in at least one time period, a distribution amount calculation unit (4) that calculates a distribution amount for each of the plurality of consumers with respect to the suppression amount before the at least one time period, a device state collection unit (6) that can collect in real time device state information regarding the states of power devices (110) for each of the plurality of consumers, a determination unit (8) that determines whether to correct the distribution amount based on the device state information collected in real time by the device state collection unit in the at least one time period, and a distribution amount correction unit (10) that corrects the distribution amount when the determination unit determines to correct the distribution amount.

[0057] According to the configuration described in [1] above, the distribution amount for each of a plurality of consumers with respect to the amount of power suppression for the entire community in at least one time period is calculated prior to at least one time period. Then, based on the device state information collected in real time in at least one time period, it is determined whether the calculated distribution amount needs to be corrected. That is, the determination of whether to correct the distribution amount takes into account the state of the power equipment in at least one time period. And the distribution amount correction unit corrects the distribution amount when the determination unit determines that the distribution amount needs to be corrected. Therefore, the amount of power suppression in at least one time period can be appropriately distributed to each of the plurality of consumers.

[0058] [2] In some embodiments, in the configuration described in [1] above, the determination unit determines not to correct the distribution amount until a first predetermined time has elapsed from the start time of the at least one time period.

[0059] Until a first predetermined time has elapsed from the start time of at least one time period, the device state information collected by the device state collection unit is not sufficient, so the accuracy of the determination by the determination unit is low, and it is not necessary to correct the distribution amount. According to the configuration described in [2] above, it is possible to suppress the correction of the distribution amount until the device state information is sufficiently collected and the accuracy of the determination by the determination unit is increased.

[0060] [3] In some embodiments, in the configuration described in [1] or [2] above, the determination unit determines not to correct the distribution amount until a second predetermined time has elapsed from the time when the distribution amount correction unit corrects the distribution amount in the at least one time period.

[0061] It takes some time for the demand households to respond to the revised allocation amount by the allocation amount correction unit. For this reason, until some time has elapsed since the time when the allocation amount was corrected, the device state information collected by the device state collection unit is not sufficient, so the accuracy of the determination by the determination unit is low, and the correction of the allocation amount is unnecessary. According to the configuration described in [4] above, the correction of the allocation amount can be suppressed until the device state information in which the corrected allocation amount is reflected in each of the plurality of demand households is sufficiently collected and the accuracy of the determination by the determination unit is increased.

[0062] [4] In some embodiments, in the configuration described in any one of [1] to [3] above, The at least one time period includes a first time period and a second time period that is continuous with the first time period and after the first time period. The suppression amount calculation unit is configured to calculate a first suppression amount of power for the entire community in the first time period and a second suppression amount of power for the entire community in the second time period. The allocation amount calculation unit is configured to calculate, before the first time period, a first allocation amount for each of the plurality of demand households with respect to the first suppression amount and a second allocation amount for each of the plurality of demand households with respect to the second suppression amount. The allocation amount correction unit is configured to correct the second allocation amount before the second time period when the determination unit determines to correct the first allocation amount in the first time period.

[0063] In the first time period, when the determination unit determines to correct the first allocation amount, it is highly likely that the second allocation amount in the second time period also needs to be corrected. According to the configuration described in [4] above, in the first time period, when it is determined to correct the first allocation amount, the second allocation amount is corrected before the second time period. For this reason, before the second time period, the suppression amount of power in the second time period can be appropriately allocated to each of the plurality of demand households.

[0064] [5] In some embodiments, in the configuration described in any one of [1] to [4] above, The power equipment includes a power-consuming device (112) that consumes power and a power generation device (114) that generates power. The device status information includes at least one of the received power amount received by the power-consuming device and the generated power amount generated by the power generation device.

[0065] According to the configuration described in [5] above, the device status collection unit can quickly collect the power shortage or surplus state from the power equipment.

[0066] [6] The power suppression distribution amount calculation method according to the present disclosure is calculating a suppression amount of power for an entire community that is an aggregate of a plurality of customers in at least one time period (S2); calculating a distribution amount for each of the plurality of customers with respect to the suppression amount before the at least one time period (S4); collecting in real time device status information regarding the status of power equipment for each of the plurality of customers in the at least one time period (S8); determining whether to correct the distribution amount based on the device status information collected in real time in the at least one time period (S10); and correcting the distribution amount when it is determined to correct the distribution amount (S12).

[0067] According to the method described in [6] above, the necessity determination of correcting the distribution amount for each of the plurality of customers takes into account the status of the power equipment in at least one time period. And when it is determined to correct the distribution amount, the distribution amount is corrected. Therefore, the suppression amount of power in at least one time period can be appropriately distributed to each of the plurality of customers.

[0068] [7] In some embodiments, in the method described in [6] above, the at least one time period includes a first time period and a second time period that is consecutive to the first time period after the first time period. The step of calculating the suppression amount calculates a first suppression amount of power for the entire community in the first time period and a second suppression amount of power for the entire community in the second time period. The step of calculating the allocation amount calculates a first allocation amount for each of the plurality of consumers with respect to the first suppression amount and a second allocation amount for each of the plurality of consumers with respect to the second suppression amount before the first time period. The step of modifying the allocation amount, when it is determined to modify the first allocation amount in the first time period, modifies the second allocation amount before the second time period.

[0069] According to the method described in [7] above, when it is determined to modify the first allocation amount in the first time period, the second allocation amount is modified before the second time period. For this reason, before the second time period, the suppression amount of power in the second time period can be appropriately allocated to each of the plurality of consumers.
