Abstract

A method of controlling a wind turbine having a rotor and a generator for producing power, the method comprising the steps of: obtaining an operational parameter, the operational parameter representing the loading experienced by the wind turbine due to a turbulence intensity acting on the rotor of the wind turbine; controlling the wind turbine in dependence on the operational parameter by altering at least one of a rotational speed setpoint of the rotor and a minimum pitch setpoint of a blade of the rotor; wherein the step of obtaining the operational parameter comprises: determining a rotor power produced by the rotor; and calculating a standard deviation of the rotor power over a period of time.
