An Study On The Pricing Strategy Of Selling Electricity Based On Game Theory

In the process of marketization of smart grid,more and more power-selling companies join the power market.As the key factor that affects the demand of the power market,the price of electricity plays an important role in the marketing strategy and demand-side management of the sales side of the smart grid.Thus,the pricing strategy is one of the key issues for sales companies to enhance the efficiency and competitiveness.This paper discuss the game model of various pricing strategies,the connection between the strategies and the respective limitations of the power company in the electricity market.Using the fitted scenario design,the non-cooperative game price model and cooperation game price model are given to provide a certain reference value for the development of electricity price.This paper studies the electricity price game model of sales company and microgrid respectively in the two scenarios of non-cooperation and cooperation.In the non-cooperative game model,by analyzing the satisfaction characteristics of different users,we determined the satisfaction characteristics of microgrids when the load proportion of all kinds of users is not the same,and then research taking the microgrid satisfaction characteristics as an important part of sales company's profit function.In this paper,a Stackelberg game model based on Particle Swarm Optimization(PSO)is used to establish a noncooperative game model for sales company and microgrid.The research shows that the sales company can use the estimated microgrid electricity consumption to analyze the customer satisfaction characteristics and demand response characteristics,and quickly decide the optimal price.At the same time,the microgrid can also choose the electricity consumption that best fits the vital interests.In the cooperative game model,traversal-based heuristic alliance cooperation model and Merge-Split-based improved alliance cooperation algorithm are established.A number of alliances are formed among the microgrids.They first trade electricity within the coalition,and then deal with electricity sales companies.The research shows that through the formation of alliances,the benefits of both microgrids and sales companies have increased and then reach a win-win result.
