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 ...

Modelling, Implementation, and Assessment of Virtual Synchronous Generator in Power Systems
Journal of Modern Power Systems and Clean Energy, 2020 As more and more power electronic based generation units are integrated into power systems, the stable operation of power systems has been challenged due to the lack of system inertia. In order to solve this issue, the virtual synchronous generator (VSG),

VSG Control Strategy Incorporating Voltage Inertia and Virtual Impedance for Microgrids
Energies, 2020 Virtual synchronous generator (VSG) control lacks voltage inertia and powerful decoupling capabilities. The voltage of the distributed generator (DG) unit controlled by the VSG will be easily affected by power fluctuations and high-frequency noise, and ...
