一种用于虚拟同步机低频稳定性增强的附加阻尼转矩方法

Low-frequency oscillations may occur in a virtual synchronous generator (VSG), resulting from an insufficient equivalent damping ration, which may be a serious stability issue for VSG. Thus, an additional damping ration is expected to be provided without affecting droop behaviors and the inertia response of VSG. To that end, an analytical approach based on combining a damping torque model and a sm...
