Abstract: A method of operating a wind turbine. The wind turbine is operated over an operating period in accordance with a control strategy. A sensor signal is received over the operating period from a sensor measuring an operational parameter of the turbine. A model is used to obtain a modelled fatigue value based on the sensor signal. The modelled fatigue value provides an estimate of fatigue loading applied to a component of the turbine over the operating period. The control strategy is modified based on the modelled fatigue value.

Abstract: A method for controlling a wind turbine connected to an electrical grid includes receiving, via a controller, a state estimate of the wind turbine. The method also includes determining, via the controller, a current condition of the wind turbine using, at least, the state estimate, the current condition defining a set of condition parameters of the wind turbine. Further, the method includes receiving, via the controller, a control function from a supervisory controller, the control function defining a relationship of the set of condition parameters with at least one operational parameter of the wind turbine. Moreover, the method includes dynamically controlling, via the controller, the wind turbine based on the current condition and the control function for multiple dynamic control intervals.

Abstract: A method for controlling an active power in a wind farm comprises inputting an active power setpoint value into the wind farm model. Splitting the active power setpoint value of the wind farm among models of the wind turbines. Determining a modeled active power setpoint value of the wind farm as a sum of modeled active power setpoint values of the wind farm model. Determining a system deviation as a difference between the modeled active power setpoint value and an actual value of the active power output of the wind farm. Inputting the system deviation into a power controller which outputs a controller manipulated variable. Determining a feedforward controller manipulated variable independently of operating states of the wind turbines of the wind farm or the active power. Determining an overall manipulated variable as the sum of the freeforward controller manipulated variable (uff) and the controller manipulated variable.
