Abstract: Introduction Considering randomness and intermittency of wind power generation, solar power generation and other renewable energy seriously affect the stability of power system, influence of micro grid containing wind, photovoltaic and storage on power grid security and stability is researched in this paper. Method First, wind system, photovoltaic system and the concrete microgrid network simulation model were established using DIgSILENT, and then steady-state and electromechanical transient calculations were carried out and corresponding control strategies were proposed. Result In the end, the general principles of control strategies about distributed generation, storage device and overall micro-grid system were proposed. Conclusion This research result provides some guidance for control strategies for micro-grid.
