摘要：The microgrid can operate in grid-connected mode and islanded mode, and the parallel operation of inverters will be involved in both modes. However, due to the differences of output characteristic among various inverters, the load power can't be shared equally. As a result, some methods without communication lines such as droop control and VSG (virtual synchronous generator) control have been proposed and extensively applied. In this paper, the power sharing characteristics of droop control and VSG control are analyzed and compared to draw the following conclusion: the dynamic power sharing performance of VSG control based inverters is better than droop control based inverters. The simulation results in PSCAD are provided to verify the conclusion.
