Abstract In order to study the operating rules of virtual synchronous generator (VSG) with pulsed load and improve the performance of the inverter with pulsed load, the simulation modeling for the VSG with pulsed load system are established. On the basis of simulation, the influence of VSG parameters, pulse load duty cycle D, peak power P and switching period T on system operating characteristics are analyzed. By comparing and analyzing different active-loop control strategies, the best VSG active-loop control strategy is selected for the pulsed load output characteristics. Proportional resonant (PR) control is adopted to eliminate the influence of coupling problems existing between traditional proportional integral (PI) control to improve the power output quality of VSG under the action of pulsed load.

Key words： virtual synchronous generator (VSG) microgrid pulse load operation characteristics proportional resonant (PR) control
