Abstract: The disclosure provides a method of controlling a wind turbine, wherein the method comprises: a) measuring and recording power output values from a sensor, and measured values from at least one of a rotor speed sensor, rotor speed controller, pitch controller or pitch position sensor for the wind turbine, during operation of the turbine with a reference pitch angle and/or rotor speed regulation curve for a time period t1; b) changing the pitch angle and/or rotor speed regulation curve(s); c) operating the wind turbine with the curve(s) from step b) during a time period t1 and receiving measured values from a wind turbine power output sensor and at least one of a rotor speed sensor, rotor speed controller, pitch controller or pitch position sensor; d) optionally repeating steps b) and c) one or more times; e) comparing a power output of the wind turbine obtained at step a) with a power output obtained in step c) during operation of the wind turbine under one or more changed pitch angle and/or rotor speed regulation curve(s); f) determining whether a power output obtained at step c) is higher than a power output obtained at step a); and g) optionally, changing the pitch angle and/or rotor speed reference curve(s) for the wind turbine to a curve or curves identified in step f) that results in higher power output than the power output measured in step a). A computer programme implementing the method, a controller configured to execute the method and a wind turbine comprising the controller are also provided.
