Zusammenfassung:	A method of controlling a wind turbine is provided. The method comprises determining a target fatigue life consumption for each of one or more components of the wind turbine; comparing the target fatigue life consumption with a measure of fatigue life consumption for each of the one or more turbine components; and controlling the turbine power output based upon the comparison. The target fatigue life consumption is determined by combining data indicative of a target rate of accumulation of fatigue damage over at least a portion of the operating life of the wind turbine and data indicative of an expected rate of accumulation of fatigue damage caused by seasonal variations in turbine operating conditions. A corresponding wind turbine controller and wind power plant controller is also provided.
