    Abstract: A method for controlling a wind turbine based on aerodynamic performance maps that account for blade twist includes controlling the wind turbine based on at least one aerodynamic performance map. Further, the method includes determining at least one speed parameter of the wind turbine. Moreover, the method includes determining a blade torsional stiffness factor. Thus, the method further includes determining, via the processor, a twist correction factor for the aerodynamic performance map as a function of the at least one speed parameter and the blade torsional stiffness factor. The method then includes applying the twist correction factor to the at least one aerodynamic performance map to obtain an adjusted aerodynamic performance map. In addition, the method includes controlling the wind turbine based on the adjusted aerodynamic performance map.

    Abstract: The present disclosure is directed to a system and method for reducing vibrations of a tower (e.g. a tubular steep tower or a lattice tower structure) of a wind turbine. The method includes continuously determining a torsional movement of the tower based at least in part on measurements obtained from one or more sensors. Another step includes continuously determining, via a controller, a control command for one or more pitch drive mechanisms of the wind turbine based on the torsional movement. Thus, the method also includes operating the one or more pitch drive mechanisms based on the control command so as to dampen the torsional movement of the tower.
