摘　　要：通过引入微分博弈理论,为解决电力系统中众多控制器动态协调的难题,提出了一种新的解决思路。以一次、二次调频间的协调为例,建立其微分博弈模型并求得开环纳什均衡解。在2区域互联系统上的仿真表明,所述方法能显著缓解一次、二次调频间的冲突反调现象,证明了微分博弈理论在电力系统协调控制领域应用的可行性和有效性。Differential game theory is introduced as a new method to solve the problem of coordinating a large number of varied controllers in a power system.The coordination between primary and secondary frequency controls is used as example application,whose differential game model is established and open-loop Nash equilibria are solved.The simulation results on the two-area connected system show that the proposed method can alleviate the conflict between primary and secondary frequency controls,and verify that the application of differential game theory in the field of power system coordinated control is feasible and effective.
