Abstract
A method for optimizing the operation of a wind turbine having a rotor with at least one rotor blade, a tower, and a wind turbine controller, comprises determining a first load status of the wind turbine based on metereological data acquired by sensors, including a turbulence intensity; determining a second load status of the wind turbine based on mechanical loads on at least one wind turbine component; and increasing a load of the wind turbine, if the determined first and second load status of the turbine are within selectable load limits. A wind turbine implementing the method is also disclosed.
