When the virtual synchronous generator (VSG) works in a grid with distorted voltages, it is difficult to guarantee the quality of its output currents. The existing harmonic suppression schemes are limited in various aspects. In this paper, a new voltage-current hybrid control (VCHC) scheme is proposed. At the fundamental frequency, VCHC is equivalent to voltage control to follow the fundamental voltage command from the VSG power control loop. VCHC is equivalent to current control at harmonic frequencies, which can suppress harmonic currents introduced by distorted grid voltages. Compared to existing methods, VCHC can greatly improve the output current quality of VSG without adding additional sensors or inductors. Finally, a 15kW experimental prototype was built and the experimental results verified the effectiveness of VCHC.
