Abstract：During the operation of an independent microgrid, a discrepancy may arise between the maximum allowable output power controlled by a traditional virtual synchronous generator (VSG) and the power consumed by the system load. This will cause system capacity overload. If the discrepancy is significant, it can lead to voltage and frequency overrunning, posing a threat to the safe operation of the system. In order to mitigate the impact of this issue on the safe operation of the system, a self-recovery control method is proposed based on the VSG control strategy and analysis of voltage and frequency deviation causes. This method aims to achieve secondary regulation of voltage and frequency during independent microgrid operation, and achieve real-time dynamic regulation of system frequency and output power. Finally, the feasibility and effectiveness of the above control method are verified by building a simulation model in Matlab/Simulink software.
