A coordinated control strategy for Photovoltaic-Battery Energy Storage System (PV-BESS) based on virtual synchronous generator (VSG) and reactive current injection is proposed in this paper. . In order to solve the problem of variable steady-state operation nodes and poor coordination control effect in photovoltaic energy storage plants, the coordination control strategy of photovoltaic energy storage plants based on ADP is studied. By investigating the influence mechanism of virtual inertia. . With the increase of photovoltaic (PV) power penetration level in the system, the requirements for PV integration is becoming stricter to guarantee the secure and stable operation of the grid. PV stations will be possibly required to perform like a synchronous generator which could participate in. .
