Abstract

According to one embodiment, an electricity control system includes a power plant, a customer and a central device connected to each other via a power line. The customer includes an electricity generator that generates electricity. The central device provides the customer with feedback of an incentive indicated by a value obtained by multiplying an electricity amount injected into a grid within an electricity amount generated in the electricity generator by a first incentive coefficient L used when the power plant has surplus electricity to supply.

Claims

1. An electricity control system comprising a power plant, a customer and a central device connected to each other via a power line, wherein

the customer comprises an electricity generator that generates electricity, and

the central device provides to the customer with feedback of an incentive indicated by a value obtained by multiplying an electricity amount injected into a grid within an electricity amount generated in the electricity generator by a first incentive coefficient L used when the power plant has surplus electricity to supply.

2. The electricity control system according to claim 1, wherein the first incentive coefficient L is obtained by a function including at least one of a unit price of electricity generated in a superior grid (adjacent grid) G₁, a unit price of electricity generated in a smart grid G₂, a price in a reference area G₃, a price determined in accordance with surplus electricity of the grid G₄, a strategic price G₅, and a past price G₆.

3. The electricity control system according to claim 1, wherein the customer is provided with the feedback of the incentive in a manner such that points are assigned, a point card or a gift card is issued, or an electricity rate is offset.

4. An electricity control system comprising a customer and a central device connected to each other via a power line, wherein

the customer comprises a receiving unit to receive a telegram transmitted from the central device to request to cut off at least one of loads,

the central device provides to the customer, when the telegram to request to cut off the load is received by the receiving unit, with feedback of an incentive indicated by a value obtained by multiplying an electricity amount assumed to be saved by cutting off corresponding load by a second incentive coefficient M used when the customer is requested to cut off the load or a third incentive coefficient N used when the load of the customer is forcibly cut off.

5. The electricity control system according to claim 4, wherein each of the second incentive coefficient M and the third incentive coefficient N is obtained by a function including at least one of a unit price of electricity generated in a superior grid (adjacent grid) G₁, a unit price of electricity generated in a smart grid G₂, a price in a reference area G₃, a price determined in accordance with surplus electricity of the grid G₄, a strategic price G₅, and a past price G₆.

6. The electricity control system according to claim 4, wherein the customer comprises a breaker switch by which external electricity supplied to a part of the loads is cut off in accordance with an instruction from the central device, and

the second incentive coefficient M used when the customer is requested to cut off the corresponding load by operating the breaker switch, is a value corresponding to a difference between a contracted ampere capacity of the customer and an available ampere capacity indicated by the central device.

7. The electricity control system according to claim 4, wherein the customer comprises a smart meter by which external electricity supplied to all of the loads is cut off in accordance with an instruction from the central device, and

the third incentive coefficient N used when the loads of the customer are forcibly cut off by the smart meter, is a value corresponding to a contracted ampere capacity of the customer.

8. The electricity control system according to claim 4, wherein the customer is provided with the feedback of the incentive in a manner such that points are assigned, a point card or a gift card is issued, or an electricity rate is offset.
