    Abstract: Systems and methods are provided for the control of a wind turbine. Accordingly, a wind classification module of a controller determines a current aerodynamic state of the wind resource based, at least in part, on a current operational data set of the wind turbine. The current operational data set is indicative of a current operation of the wind turbine. A configuration intelligence module of the controller then generates an estimated configuration for a turbine estimator module and a predictive control configuration for a predictive control module based, at least in part, on the current aerodynamic state. An operation of the wind turbine is emulated via the turbine estimator module to generate a control initial state for the predictive control module. The predictive control module then determines a predicted performance of the wind turbine over a predictive interval based on the control initial state and the predictive control configuration. The predictive control module generates a set point for at least one actuator of the wind turbine based on the predicted performance, and an operating state of the wind turbine is affected via the at least one actuator in accordance with the setpoint.

    Abstract: The present disclosure relates to devices for wind turbine blades and methods for reducing vibrations in wind turbines. More particularly, the present disclosure relates to devices for mitigating vortex induced vibrations and stall induced vibrations, wind turbine blades comprising such devices, and methods for reducing wind turbine vibrations when the wind turbine is parked, especially during wind turbine installation and/or maintenance. A method for mitigating vibrations of a parked wind turbine comprises arranging a device in an inactive state with a wind turbine blade; and causing the device to transition to an active state in which the device grips the wind turbine blade more strongly than in the inactive state.
