一种基于光伏与超级电容协调的经济型虚拟同步发电机系统

Virtual synchronous generator (VSG) control is widely adopted in grid-connected inverters owing to its ability of inertia support and primary frequency regulation. However, these benefits are achieved at the increased cost of energy storage (ES). Therefore, a cost-efficient grid-forming VSG system based on coordinated photovoltaic (PV) and supercapacitor (SC) is proposed in this article. Consideri...
