Economic Game Theory Research on Bilateral Electricity Pricing in Direct Power Purchase

The electricity pricing and the products price for large customers both affect the benefits of all participants in the course of the direct power purchase. In order to find the best pricing status, the electricity pricing and the products price are considered as the decision-making variables for the generation company and the large customers. The complete information non-cooperation bi-level programming model is built to achieve the equilibrium of all participants in the system based on game theory, and the Pareto model based on the two-layer model is built. Simulation result shows that the balancing solution of Stackelberg optimization method is better than that of the Pareto optimization method with much more stability and sustainability when all participants are rational agents in the course of the direct power purchase.
