Claim 13:
14. A method for determining a maximum power setpoint for a wind turbine comprising:
measuring a first temperature of a first electrical component of the wind turbine;
comparing the first temperature with a first temperature threshold established for the first electrical component to determine a first temperature error value corresponding to an actual temperature difference between the first temperature and the first temperature threshold;
determining a present power output of the wind turbine;
controlling a first power setpoint of the wind turbine with a first offset determined in a first control based on the first temperature error value, and a second offset determined in a second control based on the present power output of the wind turbine used as an indication of heat production in the first electrical component; and
determining the maximum power setpoint for the wind turbine to be the lower of a rated power of the wind turbine or the first power setpoint.
