Research on MW size stand-alone microgrid & its control system

Based on analyzing the research status of microgrid system,a multi-grade stand-alone microgrid system which could be used in island, desert, remote mountain areas was built.The network topology and characteristics of the system were illustrated. The scheduling control and energy management system of the microgrid were researched based on supervisory control and data acquisition(SCADA) and integration of power dispatching and distribution automation technology of traditional large power grid. The control method and flow were expounded.
