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.

Electric energy adjustment apparatus, system, method and program

System and methods for performing microgrids cooperation by optimal coalition formation in a distribution network are disclosed. A Microgrid Cooperation Module (MCM) is designed for utility EMS. MCM contains a coalition formation unit and an energy exchange decision unit. Furthermore, a communication protocol for energy exchange between two microgrids is designed. The coalition formation unit applies an innovative hierarchical coalition formation algorithm to provide optimal coalition for real time operation. The real time energy status of microgrids will be provided to coalition formation unit which will determine the coalitions (given a distance threshold) among microgrids to minimize the power loss. Energy exchange decision unit then determine actual energy transfer between pairs of microgrids within a coalition. Upon receiving the energy transfer information through a communication channel, the microgrids will start communicating and process energy transfer. The optimality of the formed coalitions is ensured by performing coalitional game theoretical analysis.
