The article focuses on the seamless switching and stability improvement of ship shore connection and grid connection.Based on the design of power controller,excitation controller,and pre synchronization controller,a virtual synchronous generator based control algorithm for ship power system and port shore power grid connection is proposed.In the Matlab/Simulink stage,the proposed control algorithm was validated,and simulation results showed that applying the proposed ship shore grid connection control algorithm can achieve seamless switching and fast synchronization of ship shore grid connection;In case of sudden load changes,the shore power system can quickly respond and increase or decrease output power in a timely manner,and the dynamic response effect meets expectations.
