Research on Energy Management and Its Control Strategies of Microgrid

In this paper, the microgrid which is composed of photovoltaic cells, microturbine, storage device and load is researched. On the basis of analysis of the typical structure of microgrid and the operation modes of every microsource, the program of energy management is presented and designed, and its control strategies are researched under the condition of both grid-connected mode and islanding mode. Several algorithmic examples have been studied through simulation, and the simulation results verify the correctness of the energy management's control strategies. The research results indicate that it can ensure the high efficiency and stability operation of microgrid through the coordinated control of energy management.
