1. A method for determining a maximum power setpoint for a wind turbine comprising:
determining a temperature of a first wind turbine component;
determining a first component temperature error by determining an actual temperature difference between the temperature of the first wind turbine component and a corresponding threshold temperature for the first wind turbine component;
determining a present power output of the wind turbine as an indication of present heat production in the wind turbine component and a future temperature of the wind turbine component; and
wherein the determination of the maximum power setpoint is based at least partially on the first component temperature error and the present power output of the wind turbine.
