    Abstract: A method is provided for operation of a wind turbine having rotor blades attached to a hub, wherein a controller compensates for torsionally induced blade twist. The method includes operating the wind turbine according to a rated power output curve and maximum design thrust value, and periodically or continuously detecting for induced torsional twist in the rotor blades. Upon determination of torsional twist being induced in the rotor blades, the method includes adjusting the maximum thrust value in the control program to compensate for the induced twist. The wind turbine controller then controls pitch of the rotor blades as a function of the increased maximum thrust value so that power output of the wind turbine is not unnecessarily limited or increased by the induced twist on the rotor blades.

    Abstract: Power generation stabilization control systems and methods include monitoring a frequency of the power grid. In response to detecting a frequency event occurring in the power grid, the method includes activating a control scheme in order to meet one or more grid requirements of the power grid. The control scheme includes increasing a power output of the wind turbine to, at least, a pre-event measured grid power. Further, the control scheme includes calculating a power correction factor for a power set point as a function of, at least, the frequency event. Moreover, the control scheme includes adjusting the power set point via the power correction factor such that the power output follows a predetermined trajectory. In addition, the control scheme includes controlling, via a turbine controller, the wind turbine based on the adjusted power set point for as long as the control scheme is activated.
