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. .

This paper focuses on the design, modeling, and analysis of the coordinated power control strategy for a grid-connected hybrid energy storage system based on VSG (VSG-HES). . Existing hybrid energy storage control methods typically allocate power between different energy storage types by controlling DC/DC converters on the DC bus. Due to its dependence on the DC bus, this method is typically limited to centralized energy storage and is challenging to apply in enhancing. . Grid-forming-type energy storage is a key technology for addressing the large-scale integration of renewable energy and achieving the goals of carbon neutrality. Virtual Synchronous Generator (VSG), due to its inertia support function, is currently the most focused grid-forming control method. Based on the optimization and control of the output behaviors of gas turbines, flexible. .
