Optimal Allocation Model of Interconnected Regional Electric Grid Based on Game Theory

The necessity of interconnecting electric power grid among regions is proved by analyzing the characteristics and problems of the interconnected power grid. This paper establishes a cooperative game model based on multi-person cooperative game by ways of game theory, and Shapley value method was adopted to solve the model. The calculation of a case results show that this cooperative game model is helpful to incarnate the influence among the members, distribution results are more rational than traditional methods. An improved model was proposed considering the personalized costs of each regional power grid. Thus it can be used for optimal decision of electricity transaction.
