Abstract：In order to reduce the carbon emissions of large ships，photovoltaic（PV）power generation

technology began to be applied to ship power systems. However，due to the limited capacity，low inertia and large

load difference of the ship power system，the traditional virtual synchronous generator（VSG）control strategy can

not effectively deal with various working conditions in the ship power network. A parameter configuration method

of VSG based on fuzzy control algorithm was proposed to improve the dynamic characteristics of VSG. Firstly，the

working state of ship power system under different working conditions was classified. Secondly，the principle of

ship PV VSG was analyzed，and the configured virtual inertia and virtual damping parameters were modeled. At the

same time，a fuzzy control algorithm was designed to realize the autonomous configuration of VSG parameters.

Finally，the simulation results showed that the strategy works well when the fluctuate was happened in source side，load side or both side. The simulation results show that the control strategy can effectively improve the power

reliability in ship grid.
