A battery energy storage based virtual synchronous generator

The purpose of this paper is to investigate the interaction of the Virtual Synchronous Generator (VSG) units with the grid. Within this scope, test-scenarios of different power systems with increasing VSG penetration levels, are simulated and evaluated. The ability of a battery storage system to provide primary frequency regulation, as part of a virtual synchronous generator, is also examined whereas several control strategies are used to properly manage the battery storage system according to the technical specifications of the ENTSO-E.
