Therefore, it has attracted great attention worldwide. Different types may play different roles in the microgrid, and their inverters also need to adopt different control strategies. At present, the common control modes for controlling distributed power inverters can be divided into: constant power control mode (PQ mode) and constant voltage/constant frequency control mode (VF mode), because according to the requirements of the microgrid system connected to the distributed power supply, the distributed power supply must have the switching function between the VF mode and the PQ mode, so design a kind of Distributed power mode switching controller is very necessary.
