POWER ADJUSTMENT SYSTEM, POWER ADJUSTMENT METHOD, AND PROGRAM

摘要

A prediction unit predicts electric power consumed by an electric load. When the electric power predicted by the prediction unit exceeds a limit value that is set to a building of a consumer, a calculation unit calculates an excess charge to be paid in addition to a price for electric power received by the building. A transaction participating unit is configured to perform an application to a transaction device when the amount of money that the consumer receives exceeds the excess charge while a first state, in which electric power from a power supply facility is supplied to a power system, is selected. A controller is configured to select the first state when the contract is concluded. The controller is configured to select a second state so that the electric power from the electric power system does not exceed the limit value unless a contract is conclude.

1. A power adjustment system that is configured to transact with a transaction device, according to a transaction condition, whether or not electric power from a power supply facility in a building of a consumer is supplied to an electric power system, the power adjustment system comprising:
a prediction unit configured to predict electric power that is to be consumed by an electric load in the building; a controller configured to select any one of a first state, in which the electric power from the power supply facility is supplied to the electric power system, and a second state, in which the electric power from the power supply facility is supplied to the electric load; a calculation unit configured to calculate an excess charge to be paid in addition to a price for electric power that the building receives from the electric power system when the electric power predicted by the prediction unit exceeds a limit value that is set to the building; and a transaction participating unit configured to be allowed to transact with the transaction device when a first amount of money received by the consumer is more than a second amount of money as the excess charge while the first state is selected.
