Abstract

Disclosed is a control system (10) provided with: a generation apparatus (220) for generating control information that is information based on demand and supply of power generated at a power plant (210), and that is to be used for controlling power at the location of consumers (301) of electric power to whom power generated at the power plant (210); and a correction apparatus (100a) for correcting the control information, taking into consideration either a distributed power supply or a storage battery that can supply power to a consumer group (300a) of electric power. Power control is executed at the location of the consumers who comprise the consumer group (300a) of electric power, using the corrected control information.

Claims

1. A control system, comprising:

a generation device configured to generate the control information that is the information based on supply and demand of power generated at an electric generation plant, and is used for power control in a plurality of consumers supplied with the power generated at the electric generation plant,

a correction device configured to correct the control information generated by the generation device in view of at least one of a dispersed power source or a battery that can supply electric power to a consumer group, which is a part of the plurality of consumers, and a control device configured to perform power control by a consumer configuring the consumer group by using the control information corrected by the correction device.

2. The control system according to claim 1, wherein the correction devices are individually provided to a plurality of consumer groups, and the individual correction devices are connected to the generation device.

3. The control system according to claim 1, wherein the correction device corrects the control information generated by the generation device in accordance with the amount of electric power that can be supplied by at least one of the dispersed power source or the battery.

4. The control system according to claim 1, wherein the consumer group is formed by one of the consumers belonging to the same region, consumers sharing the same battery, and consumers connected to the same electric feeder line.

5. The control system according to claim 1, wherein the control device performs power control in each consumer or each load.

6. The control system according to claim 1, wherein the control information includes information indicating electricity prices of the power generated at the electric generation plant, information indicating a suppliable amount of the power generated at the electric generation plant, or information indicating a usable amount of the power in the consumer which is generated at the electric generation plant.

7. A correction device, comprising:

a reception unit configured to receive from a generation device the control information that is the information based on the supply and demand of the power generated at an electric generation plant, and is used for power control in a plurality of consumers supplied with the power generated at the electric generation plant,

a correction unit configured to correct the control information received by the reception unit in view of at least one of a dispersed power source and a battery that can supply electric power to a consumer group, which is a part of the plurality of consumers, and

a transmission unit configured to transmit the control information corrected by the correction unit to a control device performing power control by a consumer configuring the consumer group.

8. A power control method, comprising:

a step of generating the control information by a generation device, wherein the control information is information based on the supply and demand of the power generated at an electric generation plant, and is used for power control in a plurality of consumers supplied with the power generated at the electric generation plant,

a step of correcting the control information generated in the generating step by a correction device in view of at least one of a dispersed power source or a battery that can supply electric power to a consumer group, which is a part of the plurality of consumers, and

a step of performing power control by a control device by a consumer configuring the consumer group by using the control information corrected in the correcting step.
