Abstract
Virtual synchronous generator control can realize the active power sharing between parallel inverters in steady state. However, the difference of inertia, damping or line impedance may cause active power overshoot and oscillation. In this paper, the active power transient process during load transition is divided into two stages. The characteristics of the two stages are analyzed by the equivalent circuit model and the small signal model model respectively. On this basis, the transient active power sharing optimization method based on virtual impedance and transient damping is proposed. Finally, the Matlab/Simulink simulation and experimental results validate the availability of the proposed method.
