A Novel Grid-demanded Power Point Tracking (GPPT) Control Method for Wind Turbines to Preserve Grid Stability with High Wind Energy Penetration

To keep a stable grid operation despite shut-down power plants, wind turbines need to provide equal ancillary services. Therefore, a sophisticated grid-demanded power point tracking (GPPT) control method is proposed. This control strategy was successfully validated on a test bench, so that it may probably run on real wind turbines.
