Methods of operating a variable speed wind turbine in an event of a power set-point limitation are described. The methods may comprise determining whether the power set-point is below or equal to a theoretical capability of the wind turbine in accordance with prevailing wind conditions. If the power set-point is below the theoretical capability, operating the wind turbine to generate power according to the power set-point, including operating the wind turbine according to a generator torque and a generator rotor speed predefined for the power set-point. Each power set-point is defined by a combination of a generator rotor speed and a generator torque, the generator rotor speed (&#x3c9;, &#x3c9;, &#x3c9;, &#x3c9;) being outside an exclusion band.
