For the traditional virtual synchronous generator output active power oscillation during grid-connected PQ operation, the steady-state performance and dynamic performance and parameter adjustment exist contradiction of regulation. A virtual synchronous generator(VSG) control strategy based on fractional differential improvement is proposed. This method adds a closed-loop zero and introduces tunable parameters. This way decouples the contradiction between dynamic performance and steady-state performance regulation, and ensures the steady-state performance of the system that is unchanged, and by changing the position of the zero-pole to increase the degree of freedom of the dynamic performance of the system; and to improve the dynamic performance of the output active power, which are verified by simulation.
