Abstract

In the microgrid, the virtual synchronous generator (VSG) technology can realize the friendly access of the distributed power supply and improve the stability of the power system. Especially for the multi-inverter micro-grid system, the inertia and the damping are important for the distributed generator (DG) system. However, the VSG inverter has a large impact current at the moment when it is switching from off-grid mode to grid-connected mode. In order to solve this problem, this paper proposes a pre-synchronization PLL control strategy including frequency compensation and amplitude compensation to realize the seamless and smooth switching of VSG inverter from off-grid mode to grid-connected mode for the multi-inverter microgrid system. And the circulation circuit is also eliminated by the proposed control. Finally, simulation verification is conducted through MATLAB/Simulink.
