The invention discloses a cooperative control method for a wind power plant participating in regional power grid frequency modulation based on a non-dominated sorting whale algorithm, and the method comprises the following specific steps: firstly, constructing a multi-source cooperative control model considering the participation of the wind power plant and a traditional hydro-thermal power generating unit in power grid frequency modulation, and further improving the dynamic response capability of a regional power grid through the wind power plant, the method aims to balance two influence targets of minimizing the deviation between the regulation power instruction value and the power response value and minimizing the total frequency modulation mileage expenditure. Then, through NSWOA, obtaining a Pareto leading edge which takes the frequency modulation mileage price and the power response total deviation as a target function, and through an entropy weight method, designing a grey target decision method to obj
