Virtual synchronous machine(VSM) enhances the frequency stability of the power grid by emulating properties of the conventional synchronous machine through a voltage source inverter. However, the output active power of the inverter sometimes may exceed its rated power limit during the response of emulated synchronous machine’s properties such as the inertial response and the droop control. This paper presents an active power limiting strategy to prevent the VSM from overloading. When the active power of the VSM approaches its power limit, the VSM turns into the overload-limiting mode and its internal frequency is actively adjusted to limit the output power rapidly. The feasibility and performance of the proposed power-limiting strategy are validated with simulation and experimental results. Furthermore, the effectiveness of the proposed method is demonstrated by on-site tests, conducted at an actual microgrid.
