Abstract: 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.

Abstract: [Problem] To provide a distributed power supply system having a plurality of micro-grids and capable of operating at low energy cost, a station control device, a control method, and a storage medium in which a control program is stored. [Solution] A station control device controls: the starting up and stopping of a distributed power supply for supplying power to a load that consumes power; the distributed power supply and said load; and the opening and closing of a switch for connecting another power supply controlled by another station control device. The station control device controls the switch and the distributed power supply on the basis of: demand power information indicating power consumed by the load; fuel efficiency information indicating the output-fuel consumption characteristics of the distributed power supply; the demand power information of another load to which another distributed power supply supplies power; and the fuel efficiency information of the other distributed power supply.
