Abstract: A wind turbine and energy storage combined frequency regulation method and a wind turbine and energy storage combined frequency regulation device are disclosed. The wind turbine and energy storage combined frequency regulation method includes: determining a power increment required to be provided by a wind turbine and energy storage combined system; determining whether a rotor of a wind turbine is controllable; in response to determining that the rotor is controllable, generating a first power increment through a first mixed feedforward and feedback control manner based on the determined power increment; while controlling the rotor, generating a second power increment based on the determined power increment; generating a third power increment through a second mixed feedforward and feedback control manner based on the determined power increment.
