Abstract: The steady-state characteristics and transient stability of power electronic inverter are largely determined by its control methods.Inverter control methods with strong disturbance stability and fast response capability can effectively ensure the stable power output of inverters in fault scenarios,reducing power shortages caused by faults,and thus improve the resilience of the power grid. Virtual oscillator control（VOC）is an emerging grid-forming control method in recent years. Compared with droop-based control strategies,it has advantages such as faster response speed and stronger stability under large disturbances.However,there is a problem of output power not following the reference value during grid connected mode,which is currently one of the key issues limiting its engineering applications.Firstly,a virtual oscillator controller based on the Poincaré bifurcation equation was designed,and a design scheme for control parameters was provided.Then,based on the power flow equation,the voltage amplitude that satisfies the feasible solution of the power flow was calculated,which was used as a voltage reference to update the input of the controller in real time. Considering the difficulty in obtaining system information,an integral control method was designed to compensate for steady-state errors,so that the active and reactive power of the inverter can follow the reference value during grid connected mode.Finally,the effectiveness of the proposed method was verified through simulation examples based on Matlab/Simulink.
