Study on Non-Cooperative Game Dispatching of Regional Power System with Wind-Thermal-Pumped Storage Power

With the increasing openness of the power market, the power generation enterprise will have more initiative power in the dispatching output, thus it is extremely important to set up the dispatching model based on the profits of power stations. In this paper, the wind power, thermal power and pumped storage power stations are three independent parties. After considering the output characteristics of various types of power stations and setting the maximization of three parties' profit as the aim and their output strategies as the decision space, a dispatching model of regional power system based on non-cooperative game theory is constructed. Besides, the Nash equilibrium's solving algorithm related to this model is given. The applicability of dispatching model of regional power system based on non-cooperative game theory is studied by example simulation. The achievement of this paper can significantly optimize the effect of combined optimal operation of wind power, thermal power and pumped storage power stations in different seasons.
