Abstract
A method and device for controlling output power in a primary frequency modulation process of a wind turbine are provided by the present disclosure. The method includes predicting a rotational speed of the wind turbine; determining frequency modulation remaining time based on the predicted rotational speed, the frequency modulation remaining time being time for which the wind turbine is able to continue to output frequency modulation power as the output power used for the primary frequency modulation without affecting a recovery of the wind turbine after the primary frequency modulation; controlling the output power based on the determined frequency modulation remaining time.
