A method of controlling a wind turbine having a rotor and a generator for producing power, the wind turbine being designed for a nominal load, the method comprising the steps of: determining a current load acting on at least a part of the wind turbine; calculating a load error, the load error representing the difference between the nominal load and the current load; controlling the wind turbine based on the load error; wherein the step of controlling the wind turbine comprises altering a parameter of the wind turbine so that the power or torque produced by the generator is altered.
