Research on Black Start Control Strategy of Photovoltaic Energy Storage System Based on Virtual Synchronous Generator Control

Nowadays, new energy sources occupy an increasingly important position in the development of power technology. Facing the increasingly complex grid structure, it is very important to ensure continuous power supply without interruption, to improve the ability to cope with grid failures, and also to restore power supply in the shortest possible time when a large-scale power outage occurs in the grid due to a fault, so the research of black start technology is crucial, and also the research of microgrid black start is one of the hot spots nowadays. In this paper, the control strategy of virtual synchronous generator is analyzed on the basis of mathematical model, and a strategy applicable to the black start of PV energy storage system is designed, and finally the strategy is tested in the simulation platform, and the black start simulation is completed.
