Abstract: Traditional virtual synchronous generator（VSG）is a primary frequency regulation technique. Afterload power changes，the frequency of microgrid cannot return to the rated level，influencing the safety of the microgrid in a severe condition. In order to avoid steady-state errors under large load fluctuations，a...
