Journal of Physics: Conference Series, 2022 Since the LAN is not supported by large power grids, energy storage systems usually serve as voltage sources during their normal operation to maintain stable frequency and voltage. In this paper, we first studied PCS control technologies for energy storage systems applicable to the LAN project and determined a VSG technical route through technical ...
