The seamless switching control strategy between grid-connected microgrid and island operation mode is an important factor to ensure its safe and stable operation. The new master-slave control strategy and the peer-to-peer control strategy are combined to control the switching process of the grid-connected mode of the micro-grid to the island mode. A microgrid simulation model combining photovoltaic cells and batteries was built on the DigSILENT/PowerFactory platform to verify the correctness of the proposed control strategy and ensure the stability of the active, reactive, voltage and frequency of the microgrid.
