Abstract: A method for controlling a wind turbine is disclosed. The wind turbine comprises a set of wind turbine blades (1), each wind turbine blade (1) being provided with profile changing means (2, 4) being configured to be in an activated state in which it changes an aerodynamic profile of the wind turbine blade (1) and in a de-activated state in which the aerodynamic profile of the wind turbine blade (1) is unchanged. The profile changing means could be in the form of air deflectors (2) or air outlets (4). Upon deciding activation of the profile changing means (2, 4), an expected impact, P, on power output of the wind turbine as a result of the decided activation of the profile changing means (2, 4), is estimated. A new reference power output, Pref,New, is provided, taking the estimated impact, P, into account. The profile changing means (2, 4) is activated, and the wind turbine is operated in accordance with P ref,New .

Abstract: The present invention refers to a method for operating a wind turbine, the wind turbine particularly comprising a tower and a rotor with rotor blades. The pitch angles of the rotor blades are adjusted to generate a force on the rotor and the tower. The force is adjusted to counteract and damp an oscillation. The adjustment is enabled by an activation decision unit, if the activation decision unit decides that certain parameters characterising the oscillation or loads of the tower indicate a requirement and/or if the activation decision unit determines that the generated force is sufficient to counteract an oscillation of the tower. In various embodiments the parameters characterising the oscillation or loads of the tower comprise current oscillations and their amplitude, an estimate of loads incurred in the turbine structure, an estimate whether damping in the near future might become necessary, an indication whether a different oscillation damping algorithm than individual blade pitch control is currently performing, and an indication whether a wind speed is above a certain portion of a rated wind speed.
