Abstract

A method for operating a wind turbine during partial load operation includes determining a power output of the wind turbine. The method also includes determining whether the power output is below a rated power of the wind turbine. If the power output is at the rated power, the method includes maintaining a speed set point of the wind turbine equal to a rated speed set point. However, if the power output is below the rated power, then the method includes varying, via a controller, the speed set point of the wind turbine as a function of a torque of the wind turbine in a non-monotonic torque-speed relationship.
