JP7702828B2 - POWER SUPPRESSION DISTRIBUTION AMOUNT CALCULATION DEVICE AND POWER SUPPRESSION DISTRIBUTION AMOUNT CALCULATION METHOD - Google Patents

Description

This disclosure relates to a power suppression distribution amount calculation device and a power suppression distribution amount calculation method.

One method for balancing the supply and demand of electricity is demand response (hereinafter referred to as DR), which encourages consumers to adjust their electricity demand (power consumption). In DR, general electricity transmission and distribution companies may request an administrator (aggregator) that manages a community of multiple consumers to curtail power during DR time periods. The aggregator distributes the amount of power curtailment to each of the multiple consumers. For example, Patent Document 1 discloses that the amount of power curtailment distributed is determined based on the consumer's past power demand, and that this amount of power curtailment is revised based on the consumer's situation immediately before the start of DR.

JP 2016-135040 A

However, the technology described in Patent Document 1 does not take into account changes in the circumstances of consumers during DR hours. As a result, the amount of power reduction during DR hours is not appropriately distributed to consumers, and it may be difficult for aggregators and consumers to achieve the power reduction requested by general electricity transmission and distribution companies, etc.

The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a power suppression distribution amount calculation device and a power suppression distribution amount calculation method that can appropriately distribute the amount of power suppression to consumers in at least one time period.

To achieve the above object, the power suppression and distribution amount calculation device includes a suppression amount calculation unit that calculates a power suppression amount for an entire community, which is a collection of multiple consumers, during at least one time period; a distribution amount calculation unit that calculates a distribution amount for each of the multiple consumers for the suppression amount prior to the at least one time period; an equipment status collection unit that can collect equipment status information related to the state of power equipment for each of the multiple consumers in real time; a determination unit that determines whether or not to modify the distribution amount based on the equipment status information collected in real time by the equipment status collection unit during the at least one time period; and a distribution amount correction unit that corrects the distribution amount when the determination unit determines that the distribution amount should be corrected.

To achieve the above object, the method for calculating the amount of power suppression and distribution includes the steps of: calculating an amount of power suppression for an entire community, which is a collection of multiple consumers, during at least one time period; calculating a distribution amount for each of the multiple consumers for the suppression amount prior to the at least one time period; collecting device status information on the state of power devices for each of the multiple consumers in real time during the at least one time period; determining whether or not to modify the distribution amount based on the device status information collected in real time during the at least one time period; and modifying the distribution amount when it is determined that the distribution amount should be modified.

The power suppression/distribution amount calculation device and power suppression/distribution amount calculation method disclosed herein can appropriately distribute the amount of power suppression to consumers in at least one time period.

The power suppression/distribution amount calculation device and power suppression/distribution amount calculation method according to the embodiment of the present disclosure will be described below with reference to the drawings. This embodiment shows one aspect of the present disclosure, does not limit the disclosure, and can be modified as desired within the scope of the technical concept of the present disclosure.

Figure 1 is a schematic diagram showing the configuration of a demand response system 100 according to one embodiment. The demand response system 100 develops a plan to suppress a specific amount of power in a specific future period.

As shown in FIG. 1, the demand response system 100 includes a general electricity transmission and distribution company 102, an aggregator 104, and a community 106 which is a collection of multiple consumers 108.

Before the arrival of a time period when electricity supply and demand is predicted to be tight (hereinafter, DR time period), the general electricity transmission and distribution company 102 requests the aggregator 104 to suppress electricity during the DR time period. The DR time period consists of one time period or multiple consecutive time periods. The general electricity transmission and distribution company 102 determines whether the electricity request has been fulfilled for each time period. When the aggregator 104 receives a DR request from the general electricity transmission and distribution company 102, it distributes the amount of electricity to be suppressed in order to fulfill the DR request to each of multiple consumers 108. The consumers 108 are, for example, factories, commercial facilities, homes, etc.

In the embodiment 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 multiple consumers 108 for the suppression amount of power during the DR 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 memory such as a ROM or RAM. The power suppression/distribution amount calculation device 1 realizes each of the functional units of the power suppression/distribution amount calculation device 1 by the processor operating (calculating, etc.) according to the instructions of a program loaded into the memory. Each functional unit of the power suppression/distribution amount calculation device 1 will be described below. Note that the power suppression/distribution amount calculation device 1 is not limited to a cloud server, and may be, for example, a computer located within the facility of the aggregator 104.

First Embodiment
(composition)
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 a first time period, and the start time of the first time period is the same as the start time of the DR time period. The general electricity transmission and distribution company 102 requests the aggregator 104 to suppress power during the first time period before the first time period arrives. 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.

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, an equipment status collection unit 6, a determination unit 8, and a distribution amount correction unit 10.

When the suppression amount calculation unit 2 receives a DR request from the general electricity transmission and distribution company 102, it calculates the amount of suppression of power 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 electricity transmission and distribution company 102, but may be less than the amount of power that can achieve the DR request of the general electricity transmission and distribution company 102.

The distribution amount calculation unit 4 calculates the distribution amount for each of the multiple consumers 108 in relation to the suppression amount before the first time slot. In other words, the distribution amount calculation unit 4 formulates a distribution plan P for achieving power suppression in the first time slot before the arrival of the first time slot. The method of formulating the distribution plan P for the first time slot 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 to the consumer 108 based on the actual amount of power suppression of the consumer 108 in response to the DR request before the first time slot. In some embodiments, the distribution amount calculation unit 4 calculates the distribution amount by taking into account the equipment status information X of the power equipment 110 of the consumer 108 collected by the equipment status collection unit 6 described later.

The equipment status collection unit 6 is configured to be able to collect equipment status information X relating to the status of the power equipment 110 for each of the multiple consumers 108 in real time. For example, the power suppression/distribution amount calculation device 1 is electrically connected to the power equipment 110 for each of the multiple consumers 108, and the equipment status collection unit 6 of the power suppression/distribution amount calculation device 1 collects the equipment status information X in real time by receiving an electrical signal transmitted from the power equipment 110. The power suppression/distribution amount calculation device 1 may be wirelessly connected to the power equipment 110, or may be wired by a dedicated line or power line.

The device status information X of the electric power device 110 will be specifically described. FIG. 3 is a diagram for explaining the device status information X of the electric power device 110 according to some embodiments. The electric power device 110 includes a power consumption device 112 and a power generation device 114. The power consumption device 112 is a device that consumes electric power transmitted and distributed from the general power transmission and distribution company 102, such as a refrigerator or boiler installed in a factory, or a lighting device or air conditioning device installed in a commercial facility or a house. The power generation device 114 is a device that generates electric power by itself, such as a generator or a storage battery that runs on city gas, LNG, light oil, heavy oil, or the like as fuel.

In the embodiment 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 amount of received power X1 received by the power consumption equipment 112 of the power equipment 110 and the amount of generated power X2 generated by the power generation equipment 114 of the power equipment 110. The amount of received power X1 is, for example, a value measured by the power meter 116 of the power W transmitted and distributed from the general power transmission and distribution company 102 to the power consumption equipment 112. The power meter 116 is configured to transmit the amount of received power X1 to the equipment status collection unit 6, for example, via the Internet. The amount of generated power X2 is, for example, a value calculated by the power generation amount calculation device 118 from the operation information Y (such as the number of units and the operation rate) of the power generation equipment 114. The power generation amount calculation device 118 is configured to transmit the amount of generated power X2 to the equipment status collection unit 6, for example, via the Internet. According to the embodiment illustrated in FIG. 3, the device status collection unit 6 collects the amount of received power X1 from the power meter 116 and collects the amount of generated power X2 from the power generation calculation device 118, so that the power surplus or shortage status of the consumer 108 can be promptly collected.

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

Returning to FIG. 2, the determination unit 8 and the distribution amount correction unit 10 will be described. The determination unit 8 determines whether or not to correct the distribution amount for each of the multiple consumers 108 calculated by the distribution amount calculation unit 4 during the first time period, based on the equipment status information X collected in real time by the equipment status collection unit 6. In other words, the determination unit 8 determines whether or not to correct the distribution plan P for the first time period, formulated by the distribution amount calculation unit 4, during the first time period, based on the equipment status information X collected in real time by the equipment status collection unit 6 during the first time period.

Here, an example of the determination method by the determination unit 8 will be described. First, the determination unit 8 calculates the average amount of power received by the community 106 per unit time (e.g., per minute) during the first time period. Specifically, the determination unit 8 calculates the amount of power received by the entire community 106 from the start time of the first time period until the elapse of the elapsed time based on the device status information X collected from the start time of the first time period until the elapse of the elapsed time. Then, the determination unit 8 calculates the average amount of power received by dividing this amount of power by the elapsed time. When at least one consumer 108 has a power generation device 114, the average amount of power received is calculated by subtracting the amount of power generated from the amount of power received by the entire community 106 from the start time of the first time period until the elapse of the elapsed time by the elapsed time. Note that the time elapsed from the start time of the first time period does not exceed the end time of the first time period.

In some embodiments, if the elapsed time is the time that has elapsed since the start time of the first time slot, the average power received is the average value per unit time of the amount of power received by the entire community 106 from just before the elapsed time to the elapsed time. Just before the elapsed time refers to a preset time in the past from the elapsed time, for example, two minutes before the elapsed time. With this configuration, the determination unit 8 can determine whether or not to modify the distribution plan P for the first time slot, taking into account only the state close to the latest state of the power equipment 110 of the consumer 108.

Next, the determination unit 8 calculates the average target amount of received power of power supplied per unit time to the community 106 during the first time slot. Specifically, the determination unit 8 calculates the average target amount of received power by dividing the value obtained by subtracting the suppression amount from the predicted value (baseline) of power consumed during the first time slot when there is no DR request by the length of the first time slot. Then, the determination unit 8 determines that the distribution plan P for the first time slot is to be revised if the average target amount of received power is less than the average amount of received power. On the other hand, the determination unit 8 determines that the distribution plan P for the first time slot is not to be revised if the average target amount of received power is greater than the average amount of received power. In some embodiments, the determination unit 8 determines that the distribution plan P for the first time slot is to be revised if the average target amount of received power is less than the average amount of received power x α (α is a numerical value less than 1). α is, for example, a numerical value equal to or greater than 0.8. The length of the first time slot is the time elapsed from the start time to the end time of the first time slot, and is, for example, 30 minutes.

When the determination unit 8 determines that the distribution amount for each of the multiple consumers 108 should be corrected, the distribution amount correction unit 10 corrects the distribution amount for each of the multiple consumers 108. In other words, when the determination unit 8 determines that the distribution plan P for the first time slot should be corrected, the distribution amount correction unit 10 corrects the distribution plan P for the first time slot. The corrected distribution amount for each of the multiple consumers 108 is output to the outside of the power suppression and distribution amount calculation device 1, and is notified to the consumer 108 corresponding to this distribution amount. When the determination unit 8 determines that the distribution plan P for the first time slot should not be corrected, the distribution plan P for the first time slot is output to the outside of the power suppression and distribution amount calculation device 1 without being corrected by the distribution amount correction unit 10.

Here, an example of a correction method by the distribution amount correction unit 10 will be described. Based on the equipment status information X collected in real time by the equipment status collection unit 6, the distribution amount correction unit 10 selects, from among the multiple consumers 108, a first consumer 108A for which it is predicted that it will be difficult to suppress power to satisfy the distribution amount notified in advance, and a second consumer 108B excluding the first consumer 108A. Then, the distribution amount correction unit 10 reduces the distribution amount to be redistributed to the first consumer 108A, and increases this reduced distribution amount to the distribution amount to be distributed to the second consumer 108B.

The distribution amount correction unit 10 may be configured to re-correct the distribution amount corrected by the distribution amount correction unit 10 during the first time period. In some embodiments, the determination unit 8 determines whether or not to re-correct the distribution amount corrected by the distribution amount correction unit 10 for each of the multiple consumers 108 during the first time period, based on the equipment status information X collected in real time by the equipment status collection unit 6. When the determination unit 8 determines that the distribution amount should be re-corrected, the distribution amount correction unit 10 re-corrects the distribution amount for each of the multiple consumers 108.

(Action and Effects)
According to the first embodiment, the need for modification of the distribution plan P for the first time slot is determined based on the equipment status information X collected in real time during the first time slot. That is, the need for modification of the distribution plan P for the first time slot is determined taking into account the state of the electric equipment 110 in the first time slot. Then, the distribution amount modification unit 10 modifies the distribution plan P for the first time slot when the determination unit 8 determines that the distribution plan P for the first time slot should be modified. This can improve the accuracy of the distribution plan P for the first time slot and increase the possibility of achieving a DR request.

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 slot. The second time t2 is the time when the first time Δ1 has elapsed since 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 for the first time slot is corrected). The fourth time t4 is the time when the second time Δ2 has elapsed since the third time t3. The fifth time t5 is the end time of the first time slot.

The states of the determination unit 8 include a first state s1 in which it is determined whether or not to modify the distribution plan P for the first time slot based on the equipment status information X collected in real time during the first time slot, and a second state s2 in which it is determined not to modify the distribution plan P for the first time slot regardless of the equipment status information X collected in real time. The first time Δ1 is a time for accumulating the equipment status information X required to make the determination by the determination unit 8 more accurate than a certain level, and is determined in advance. The second time Δ2 is a time required for the consumer 108 to respond to the modified distribution plan P for the first time slot, and is determined in advance. The second time Δ2 is, for example, a time required for the amount of power generated by the power generation equipment 114 of the consumer 108 to reach a target value (the amount of power generation that can achieve the DR request) after the distribution amount is notified to the consumer 108.

As shown in FIG. 4, in some embodiments, the state of the determination unit 8 is the second state s2 from the first time t1 to the second time t2. In other words, the determination unit 8 determines that the distribution amount (distribution plan P for the first time slot) will not be revised until the first time Δ1 has elapsed from the start time of the first time slot.

Before the first time Δ1 has elapsed from the start time of the first time slot, the equipment status information X collected by the equipment status collection unit 6 is insufficient, so the accuracy of the judgment by the judgment unit 8 is low and there is no need to modify the distribution plan P for the first time slot. According to the configuration illustrated in FIG. 4, it is possible to prevent modification of the distribution plan P for the first time slot until sufficient equipment status information X is collected and the accuracy of the judgment by the judgment unit 8 becomes high.

As shown in FIG. 4, in some embodiments, the state of the determination unit 8 is the second state from the third time t3 to the fourth time t4. In other words, when the distribution amount correction unit 10 corrects the distribution amount (distribution plan P for the first time period) in the first time period, the determination unit 8 determines that the distribution amount will not be corrected until the second time Δ2 has elapsed since the time when the distribution amount correction unit 10 corrected the distribution amount.

It takes some time for the consumer 108 to respond to the revised distribution plan P for the first time slot. For this reason, until some time has passed since the time when the distribution plan P for the first time slot is revised, the equipment status information X collected by the equipment status collection unit 6 is insufficient, so the accuracy of the judgment by the judgment unit 8 is low and revision of the distribution plan P for the first time slot is unnecessary. According to the configuration illustrated in FIG. 4, it is possible to collect sufficient equipment status information X after the consumer 108 responds to the revised distribution plan P for the first time slot, and to prevent revision of the distribution plan P for the first time slot until the accuracy of the judgment by the judgment unit 8 becomes high.

In the embodiment illustrated in FIG. 4, the state of the determination unit 8 is the first state s1 during the first time slot excluding the first time t1 to the second time t2 and the third time t3 to the fourth time t4. 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. With this 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 during the first time slot, a distribution plan P for the first time slot can be quickly formulated that takes the unintended event into account.

Second Embodiment
A power suppression and distribution amount calculation device 1 according to a second embodiment of the present disclosure will be described. The second embodiment adds functions of a suppression amount calculation unit 2, a distribution amount calculation unit 4, and a distribution amount correction unit 10. In the second embodiment, the same components as those in the first embodiment are given the same reference numerals, and detailed descriptions thereof will be omitted.

(composition)
FIG. 5 is a schematic functional block diagram of the power suppression/distribution 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 subsequent to the first time period and is continuous with the first time period. Before the first time period arrives, the general power transmission and distribution company 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 the suppression of power in the first time period and the suppression of power in the second time period. As shown in FIG. 2, the power suppression/distribution amount calculation device 1 calculates, in addition to the distribution plan P for the first time period, a second distribution plan P2 for the second time period, which is a distribution amount for each of the multiple consumers 108 with respect to the amount of power suppression in the second time period.

When the suppression amount calculation unit 2 receives a DR request, it calculates the power suppression amount for the entire community 106 in the first time period (first suppression amount) and the power suppression amount for the entire community 106 in the second time period (second suppression amount). The first suppression amount and the second suppression amount may be different values or may be equal values.

The distribution amount calculation unit 4 calculates, prior to the first time slot, a distribution amount (first distribution amount) for each of the multiple consumers 108 for the first suppression amount, and a distribution amount (second distribution amount) for each of the multiple consumers 108 for the second suppression amount. The first distribution amount corresponds to the distribution plan P for the first time slot described above, and the second distribution amount corresponds to the second distribution plan P2 for the second time slot described above.

If the determination unit 8 determines that the first distribution amount should be modified during the first time period, the distribution amount modification unit 10 modifies the second distribution amount before the second time period. The modified second distribution amount is then output to the outside of the power suppression and distribution amount calculation device 1, and is notified to the consumer 108 corresponding to this second distribution amount before the second time period. If the determination unit 8 determines that the first distribution amount should not be modified during the first time period, the second distribution amount is output to the outside of the power suppression and distribution amount calculation device 1 without being modified by the distribution amount modification unit 10.

(Action and Effects)
When the determining unit 8 determines that the first distribution amount should be modified in the first time slot, it is highly likely that the second distribution amount also needs to be modified. This is because, for example, when an unintended event (e.g., a failure) occurs in the electric power device 110 of the consumer 108 in the first time slot, it is highly likely that this will affect the suppression of power of the consumer 108 in the second time slot.

According to the second embodiment, the distribution amount correction unit 10 corrects the second distribution amount when the determination unit 8 determines that the first distribution amount should be corrected during the first time period. This makes it possible to improve the accuracy of the second distribution amount before the second time period and increase the possibility of achieving the DR request.

<Power control distribution amount calculation method>
6 is a flowchart of a power suppression and distribution amount calculation method according to an embodiment. As shown in FIG. 6, the power suppression and 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.

In the reduction amount calculation step S2, the amount of power reduction for the entire community 106 during the first time period is calculated.

In the distribution amount calculation step S4, the distribution amount for each of the multiple consumers 108 is calculated for the suppression amount calculated in the suppression amount calculation step S2 before the first time slot. That is, in the distribution amount calculation step S4, a distribution plan P for the first time slot is formulated.

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

In the collection step S8, equipment status information X regarding the status of the power equipment 110 for each of the multiple consumers 108 is collected in real time during the first time period.

In the determination step S10, it is determined whether or not to modify the distribution plan P for the first time slot based on the device status information X collected in real time in the collection step S8 during the first time slot. If it is determined that the distribution plan P for the first time slot is to be modified (S10: Yes), the process proceeds to the modification step S12. If it is determined that the distribution plan P for the first time slot is not to be modified (S10: No), the process returns to the collection step S8.

In the correction step S12, if it is determined in the determination step S10 that the distribution plan P for the first time slot should be corrected, the distribution plan P for the first time slot is corrected. Then, when the correction of the distribution plan P for the first time slot is completed, the process returns from the correction step S12 to the distribution amount notification step S6. In the distribution amount notification step S6, the distribution plan P for the first time slot corrected in the correction step S12 is notified to the consumer 108 in the first time slot.

According to this method for calculating the amount of power suppression and distribution, the state of the power devices 110 in the first time slot is taken into consideration when determining whether or not the distribution plan P for the first time slot needs to be revised. Then, if it is determined that the distribution plan P for the first time slot needs to be revised, the revised distribution plan P for the first time slot is notified to the consumer 108. This makes it possible to improve the accuracy of the distribution plan P for the first time slot and increase the possibility of achieving the DR request.

In some embodiments, the suppression amount calculation step S2 calculates the power suppression amount (first suppression amount) for the entire community 106 in the first time period, and the power suppression amount (second suppression amount) for the entire community 106 in the second time period. The distribution amount calculation step S4 calculates the distribution amount (first distribution amount) for each of the multiple consumers 108 for the first suppression amount and the distribution amount (second distribution amount) for each of the multiple consumers 108 for the second suppression amount before the first time period. If it is determined that the first distribution amount is to be corrected in the first time period, the correction step S12 corrects the second distribution amount before the second time period. Then, the distribution amount notification step S6 notifies the consumers 108 of the second distribution amount corrected in the correction step S12 in the first time period.

According to this method of calculating the power suppression distribution amount, if it is determined that the first distribution amount should be revised in the first time period, the second distribution amount is revised, and this revised second distribution amount is notified to the consumer 108. Therefore, it is possible to improve the accuracy of the second distribution amount before the second time period, and increase the possibility of fulfilling the DR request.

The contents described in each of the above embodiments can be understood, for example, as follows:

[1] A power suppression and distribution amount calculation device (1) according to the present disclosure,
a power suppression amount calculation unit (2) that calculates a power suppression amount for an entire community (106) that is a collection 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;
An equipment status collection unit (6) capable of collecting equipment status information relating to the status of the electric power equipment (110) for each of the plurality of consumers in real time;
a determination unit (8) that determines whether or not to modify the distribution amount based on the device status information collected in real time by the device status collection unit during the at least one time period;
and a distribution amount correction unit (10) that corrects the distribution amount when the determination unit determines that the distribution amount should be corrected.

According to the configuration described in [1] above, the distribution amount for each of the multiple consumers with respect to the amount of power suppression for the entire community in at least one time period is calculated at least before one time period. Then, the calculated distribution amount is determined whether or not it needs to be revised based on equipment status information collected in real time during at least one time period. In other words, the determination of whether or not the distribution amount needs to be revised takes into account the state of the power equipment in at least one time period. Then, the distribution amount revision unit revisions the distribution amount when the determination unit determines that the distribution amount should be revised. Therefore, the amount of power suppression in at least one time period can be appropriately distributed to each of the multiple consumers.

[2] In some embodiments, in the configuration described in [1] above,
The determination unit determines that the distribution amount should not be modified until a predetermined first time has elapsed from a start time of the at least one time slot.

Until the first hour has elapsed from the start time of at least one time period, the device status information collected by the device status collection unit is insufficient, so the accuracy of the judgment by the judgment unit is low and correction of the distribution amount is not necessary. According to the configuration described in [2] above, correction of the distribution amount can be suppressed until sufficient device status information is collected and the accuracy of the judgment by the judgment unit becomes high.

[3] In some embodiments, in the configuration described in [1] or [2] above,
When the distribution amount correction unit corrects the distribution amount during the at least one time period, the judgment unit determines that the distribution amount will not be corrected until a predetermined second time has elapsed from the time when the distribution amount correction unit corrected the distribution amount.

It takes some time for the consumer to respond to the distribution amount corrected by the distribution amount correction unit. For this reason, until some time has passed since the time the distribution amount was corrected, the equipment status information collected by the equipment status collection unit is insufficient, so the accuracy of the judgment by the judgment unit is low and correction of the distribution amount is not necessary. According to the configuration described in [4] above, it is possible to suppress correction of the distribution amount until sufficient equipment status information reflecting the corrected distribution amount for each of the multiple consumers is collected and the judgment by the judgment unit becomes highly accurate.

[4] In some embodiments, in the configuration according to any one of [1] to [3] above,
the at least one time period includes a first time period and a second time period subsequent to the first time period and consecutive to 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 distribution amount calculation unit is configured to calculate, prior to the first time slot, a first distribution amount for each of the plurality of consumers with respect to the first suppression amount and a second distribution amount for each of the plurality of consumers with respect to the second suppression amount;
The distribution amount correction unit is configured to correct the second distribution amount before the second time period when the determination unit determines in the first time period that the first distribution amount should be corrected.

If the determination unit determines that the first distribution amount should be modified in the first time slot, it is highly likely that the second distribution amount in the second time slot will also need to be modified. According to the configuration described in [4] above, if the determination unit determines that the first distribution amount should be modified in the first time slot, the second distribution amount is modified before the second time slot. Therefore, the amount of power suppression in the second time slot can be appropriately distributed to each of the multiple consumers before the second time slot.

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

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

[6] The power suppression and distribution amount calculation method according to the present disclosure includes:
A step (S2) of calculating an amount of power suppression for an entire community, which is a collection of a plurality of consumers, in at least one time period;
A step (S4) of calculating a distribution amount for each of the plurality of consumers with respect to the suppression amount before the at least one time period;
A step (S8) of collecting equipment status information regarding a status of an electric power device for each of the plurality of consumers in real time during the at least one time period;
A step (S10) of determining whether or not to modify the distribution amount based on the device status information collected in real time during the at least one time period;
and a step (S12) of correcting the distribution amount when it is determined that the distribution amount should be corrected.

According to the method described in [6] above, the state of the electric power equipment in at least one time period is taken into consideration when determining whether or not the distribution amount needs to be revised for each of the multiple consumers. Then, if it is determined that the distribution amount needs to be revised, the distribution amount is revised. Therefore, the amount of power suppression in at least one time period can be appropriately distributed to each of the multiple consumers.

[7] In some embodiments, in the method according to [6] above,
the at least one time period includes a first time period and a second time period subsequent to the first time period and consecutive to the first time period;
the step of calculating a power suppression amount includes calculating a first power suppression amount for the entire community in the first time period and a second power suppression amount for the entire community in the second time period;
The step of calculating the distribution amount includes calculating, before the first time slot, a first distribution amount for each of the plurality of consumers with respect to the first suppression amount and a second distribution amount for each of the plurality of consumers with respect to the second suppression amount;
In the step of correcting the distribution amount, when it is determined that the first distribution amount is to be corrected in the first time period, the second distribution amount is corrected before the second time period.

According to the method described in [7] above, if it is determined that the first distribution amount is to be revised in the first time slot, the second distribution amount is revised before the second time slot. Therefore, the amount of power suppression in the second time slot can be appropriately distributed to each of the multiple consumers before the second time slot.
