Micro-grid is a small power grid consisting of micro power, energy storage equipment, control devices and loads. In the resource shortage, environmental problems, power grid security and many other pressures, the concept of micro-grid once put forward quickly by the country's attention, become a hot issue. At the same time, with the gradual deepening of micro-grid research, micro-grid operation and island operation has become an urgent need to solve the problem. In this paper, the dynamic simulation model of photovoltaic power generation, permanent magnet direct drive wind power generation, micro gas turbine, fuel cell and battery is established. The correctness of the simulation model established in this paper is verified, which lays the foundation for the economic optimization of micro-grid by using PSCAD / EMTDC software.
