摘要：
An islanded microgrid with synchronous generators (SGs) and virtual synchronous generators (VSGs) exhibits poor transient load sharing between SGs and VSGs after large load disturbance. The VSGs initially pick up the majority of load in short time, and part of them may become overload. This paper analyzes the mechanism behind the transient load sharing in such mixed-source microgrids. Then, an improved virtual impedance control is proposed for VSG to improve transient load sharing. Finally, simulation is performed to validate the analysis and proposed method.
