Two improved control strategies for rotor speed protection and recovery in the frequency support process of grid-forming wind turbines

Journal of Renewable and Sustainable Energy
Traditional grid-following virtual inertia control wind turbines (WTs) typically achieve rotor speed protection (RSP) and recovery (RSR) through adjusting coefficients. However, for grid-forming (GFM) virtual synchronous generator (VSG) controlled WTs, due to the coupling between parameters and damping characteristics, the adjustment range is limited ...
