Electric power management system and electric power management method
First Claim
1. An electric power management system for managing an electric power system having a plurality of first consumers each having a photovoltaic system, and a plurality of second consumers each having a controllable load, connected thereto,wherein each first consumer includes a consumer energy management system for controlling the amount of electric power generated by the photovoltaic system, and each second consumer includes a consumer energy management system for controlling the controllable load,wherein the electric power management system includes a server apparatus that transmits data to the consumer energy management systems and that receives data from the consumer energy management system via a network,wherein the server apparatus combines two or more consumers from among said plurality of first consumers and the second consumers so that the amount of electric power needed by each combined second consumer will be equal to or greater than the amount of surplus electricity generated at each combined the first consumer in a predetermined time slot on a predetermined date on which surplus electricity of the photovoltaic system is expected to be generated, and makes the controllable load consume the surplus electricity generated at each combined first consumer by controlling the consumer energy management system of each combined second consumer.

Abstract
The HEMS of each consumer transmits the amount of surplus electricity that is expected by to be generated by a PV system, and/or the amount of electric power that is needed by a controllable load, in a predetermined time slot on a predetermined date, to a server apparatus. The server apparatus, based on the notified amount of surplus electricity and the amount of electric power that is needed by the controllable load, combines a first consumer and a second consumer so that the amount of electric power needed by the controllable load will be equal to or greater than the amount of surplus electricity. Then, under the control the HEMS of the second consumer, the surplus electricity that is generated by the first consumer is consumed by each controllable load.

15. A server apparatus for managing an electric power system having a plurality of first consumers each having a photovoltaic system, and a plurality of second consumers each having a controllable load, connected thereto, comprising:
-
a communication control device that receives the amount of surplus electricity, that is expected to be generated in a predetermined time slot on a predetermined date on which surplus electricity of the photovoltaic system is expected to be generated, from each first consumer, and that receives the amount of electric power, that is needed by the second consumer in the predetermined time slot on the predetermined date, from each second consumer; and a processing unit that combines two or more consumers from among said plurality of first consumers and second consumers so that the amount of electric power needed by each combined second consumer will be equal to or greater than the amount of surplus electricity that is generated at each combined first consumer in the predetermined time slot on the predetermined date, and makes the controllable load consume the surplus electricity that is generated at each combined first consumer by controlling the consumer energy management system of each combined second consumer. - View Dependent Claims (16, 17)
