Aiming at the problems of low power distribution accuracy, small inertia and circulating power in the traditional control strategy of parallel interfacing converter, a virtual synchronous generator (VSG) control strategy for AC/DC hybrid microgrid parallel interfacing converter is proposed. A small AC voltage signal source is injected into the DC/DC converter of the DC subgrid, and the power-voltage droop control is changed into the power-frequency droop control. Then, the local bus DC voltage collected originally is changed into global DC superimposed frequency, and the difference between the superimposed frequency of DC subgrid and the virtual frequency of VSG is taken as the mechanical torque of VSG. By comparing the simulation results with the traditional control strategy, the effectiveness and superiority of the proposed method are verified.
