Abstract: As a large number of thermal power units in the power system are gradually replaced by wind turbines to achieve the dual carbon goals, the inertia level and frequency modulation capability of the power system are gradually weakened, which poses challenges to the safe and stable operation of the power system. Therefore, the frequency safety factor must be fully considered. Firstly, based on the equivalent swing equation of power system, a frequency security constraint model of the system considering the joint participation of wind power and energy storage in frequency modulation is established in this paper. The model is then embedded into the optimal control model to construct an optimal control model with frequency safety constraints. In order to solve the problems of high computational complexity, large scale and non-intercommunication between systems in the centralized optimization method, a multi-region cooperative optimization solution framework based on decomposition coordination principle is proposed in this paper. The alternating direction method of multipliers is used to solve the distributed optimal control model. Finally, the proposed method is validated by an improved IEEE-39 node system. The numerical results show that the proposed method can not only improve the frequency modulation capability and operation speed of the system, but also ensure the stable operation of the high-proportion wind power system.
