Design Of Power Source Micro Source Synchronous Grid Connected Controller

The voltage amplitude, frequency and phase difference exist on both sides of the grid point, and it is easy to have a great impact on the microgrid system and affect the stability of the whole system at the moment of grid connection, resulting in the whole microgrid system can not operate normally. Therefore, the synchronous grid controller is designed to control the output voltage of the distributed power supply, so that it can meet the grid connection standard of ieee1547, and reduce the impact of the distributed power supply on the islanding micro grid system. It also ensures the security of distributed power supply. Through simulation analysis, the effectiveness of the designed synchronous grid connected controller is verified.
