Virtual synchronous generators: A survey and new perspectives
A comprehensive survey on the VSG literature, VSG topologies and achievements are presented. The fundamentals and concept of VSG as a solution towards stability improvement of future grids are addressed. The paper addresses a new VSG-based frequency control scheme. We focused on the poetical of VSGs in the grid frequency regulation task. The main relevant technical challenges, key issues, and further research needs are also emphasized.
