A Service Provider (SP) includes a controller that instructs several Producers (provide the electric energy) and Consumers (consume the electric energy) about the electrical energy. The controller selects one of the Producers as an Active Producer (AP) that provides a predetermined volume of the electric energy, one of a remainder of the Producers as a Passive Producer (PP) that adjusts a volume of provided electric energy to be, one of the Consumers as an Active Consumer (AC) that consumes a predetermined volume of the electric energy, and one of a remainder of the Consumers as a Passive Consumer (PC) that adjusts a volume of consumed electric energy, and the controller instructs one of Passive Subscribers (either the PP or the PC) to adjust the electric energy, so as to mitigate a difference between a total supply volume and a total demand volume. |
