Abstract

Technique is provided in which, with respect to adjustment of power use of a customer belonging to an agent, a result of the amount of adjustment pertaining to the agent is to calculated. A power demand adjustment system for adjusting power demand of a customer who concludes a power use contract via an agent, this power demand adjustment system including: an acquisition unit that acquires facility information indicating a customer facility for power use, and result information indicating a result of the power use of the customer; and a calculation unit that calculates, on the basis of the acquired facility information and the acquired result information, an actual adjustment amount, which is the result of power demand adjustment pertaining to the agent.

Claims

1. A power demand adjustment system for adjusting power demand of a customer who concludes a power use contract via an agent, the power demand adjustment system comprising:

an acquisition unit that acquires facility information indicating a customer facility for power use, and result information indicating a result of the power use of the customer; and

a calculation unit that calculates, on the basis of the acquired facility information and the acquired result information, an actual adjustment amount, which is the result of power demand adjustment pertaining to the agent.

2. A power demand adjustment system according to claim 1, wherein

the acquisition unit acquires a scheduled adjustment amount, which is a scheduled amount of the adjustment pertaining to the agent, and

the calculation unit evaluates the actual adjustment amount by comparing the scheduled adjustment amount with the actual adjustment amount.

3. A power demand adjustment system according to claim 2, wherein the acquisition unit acquires an application adjustment amount, which is an applied amount of the adjustment pertaining to the agent,

the power demand adjustment system further comprising:

a determination unit that determines the scheduled adjustment amount on the basis of the facility information and the application adjustment amount.

4. A power demand adjustment system according to claim 3, wherein the determination unit calculates, on the basis of the facility information, an upper limit for the amount of adjustment pertaining to the agent, and when the application adjustment amount is equal to or larger than the upper limit, determines the scheduled adjustment amount on the basis of the application adjustment amount.

5. A power demand adjustment system according to claim 4, wherein

the acquisition unit acquires a required amount of adjustment, which is an amount of adjustment that is required,

the calculation unit calculates an actual adjustment amount for each of a plurality of agents, and

the determination unit determines a scheduled adjustment amount for each of the plurality of agents by distributing the required amount of adjustment to the plurality of agents on the basis of the facility information.

6. A power demand adjustment system according to claim 5, wherein

the customer concludes power use contracts with the plurality of agents, and

the calculation unit, on the basis of the result information, calculates an actual adjustment amount for each of the plurality of agents by distributing the amount of adjustment based on the customer result information to the plurality of agents.

7. A power demand adjustment system according to claim 6, wherein

the acquisition unit acquires type information indicating a type of adjustment by the customer, and

the determination unit determines a scheduled adjustment amount for each of the plurality of agents on the basis of the facility information and the type information.

8. A power demand adjustment system according to claim 7, wherein the calculation unit calculates an actual adjustment amount for each of the plurality of agents on the basis of the facility information and the type information.

9. A power demand adjustment system according to claim 8, wherein the determination unit sends incentive information indicating an incentive for each of types of power demand adjustments to the agent.

10. A power demand adjustment system according to claim 9, wherein the determination unit determines a scheduled adjustment amount for each of the plurality of agents on the basis of the facility information and the incentive information.

11. A power demand adjustment system according to claim 10, wherein the facility information includes information indicating the magnitude of the power demand by the customer.

12. A power demand adjustment system according to claim 11, wherein the facility information includes information indicating the size of the customer facility.

13. A power demand adjustment system according to claim 12, wherein the result information includes a result of power use measured inside the customer facility.

14. A power demand adjustment method for adjusting power demand of a customer who concludes a power-use contract via an agent, the power demand adjustment method comprising:

acquiring, using a power demand adjustment apparatus, facility information indicating a customer facility for power use, and result information indicating a result of power use of the customer; and

calculating, using the power demand adjustment apparatus, on the basis of the acquired facility information and the acquired result information, an actual adjustment amount, which is a result of power demand adjustment pertaining to the agent.
