Abstract
A method for controlling a wind turbine system is provided. The wind turbine system includes a power conversion assembly for converting electrical power into a converted electrical power. The method includes monitoring a power extraction parameter, wherein the power extraction parameter is indicative of the power extracted by the wind turbine system from the wind prior to being converted in the power conversion assembly. The method further includes controlling one or more operational variables of the wind turbine system in response to monitoring the power extraction parameter.
