Adaptability Among Power Source, Power Grid and Load Based on Game Theory

The coordinated development of power grid and load is one of the basic factors to optimize the social resources and to improve the equipment utilization. The decision makers of power grid and load are different. And their focuses are also different. These may result the two partner may of missing each other in the development. And these may lead to oc- currence of idle equipment or bayonet of power supply. Therefore, improving the level of mutual adaptation of power grid and the load development is the necessary condition to promote the coordinated development of power grid and load. In this paper, a method is proposed to analysis the adaptability level of power grid and load. The method establishes a game model of power grid and load. And optimal power flow is applied to analysis of interaction between power grid and load. Incomes of power grid and load in various strategies are calculated to establish the Nash equilibrium. These explain be- haviors of power grid and load respectively. And these provide the basis for the decision. The proposed method is applied in two systems.
