    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).

    Abstract: The invention relates to a method for regulating a power ramp rate of a wind park at a point of common coupling (PCC) between the wind park and a utility grid, wherein the wind farm comprises a plurality of wind turbines each having a power ramp rate dependent on a power output of the respective wind turbine. The method comprises receiving a power reference for the wind park; determining the power ramp rate of the wind park as a function of the power output of each individual wind turbine, wherein the power ramp rate of the wind park is based on the power ramp rates of the individual wind turbines and determining a corresponding plurality of power set-points for the plurality of wind turbines based on the power ramp rates of the plurality of wind turbines and power reference for the wind park. The corresponding plurality of power set-points is dispatched to the plurality of wind turbines for regulating the power ramp rate of the wind park in dependency of the power ramp rates of the plurality of wind turbines.
