Energy management system for multi-microgrid

EMS of microgrid (I-IEMS) is developed to monitor and control distributed generator (DG). It i s necessary t o research practical I-IEMS for large-scale multi-microgrid. Energy Management System for microgrid in this paper is based on Smart Grid Dispatching Technical Support System (SGDTSS) which has been widely used in dispatching system of provincial or regional power grid. The secure operating system, database, SOA function, application interface and mes sage bus are all included in special dispatching technical support platform for μEMS. The functionalities of μEMS advanced application are presented, including topology engine with multi-microgrid, power flow control, economic operation for microgrid, DGs & loads forecast, demand response based on microgrid, “Seamless Transfer” between grid and island mode, etc.
