Electricity distribution system with dynamic cooperative microgrids for real-time operation

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.
