Abstract: The invention relates to a method for utilizing a cooling system of a wind turbine. The method includes obtaining a temperature (T) which correlates with a nacelle temperature or a nacelle component temperature, obtaining a wind speed (v), determining a temperature threshold (Tth) of a power de-rating function 5 dependent on the wind speed, where the power de-rating function provides power references (Pref_i) as a function of the temperature and where the power references for temperatures above the temperature threshold are reduced compared to power references for temperatures below the temperature threshold, and determining a power reference (Pref) for the wind turbine based on the power 10 de-rating function and the temperature (T).
