一种基于逆变器的柔性微电网接地方案

Due to multiple operation modes and corresponding mode transitions of microgrids (MGs), the MG grounding design is challenging. An MG may lose its grounding provided by the main distribution grid when it transitions to the islanded operation, resulting in potential hazards to both equipment and personnel. Existing transformer-based grounding schemes are bulky and have low control capability, which...
