Frequency support Scheme based on parametrized power curve for de-loaded Wind Turbine under various wind speed [PDF]
Wind Engineering 46 (2022) 459-479, 2021 With increased wind power penetration in modern power systems, wind plants are required to provide frequency support similar to conventional plants. However, for the existing frequency regulation scheme of wind turbines, the control gains in the auxiliary frequency controller are difficult to set because of the compromise of the frequency regulation ...
