Study On TOU Power Price In Demand Side Based On Game Theory

Since 2003, the electric demand have been greater than supply, leading to large areas of the country lack of power, the electricity market reform have been covered with shadow. On the other hand, the value of our units electric power need relatively high raw material consumption, using energy is inefficient. To solve the contradictions of growth in energy demand and supply and the inefficient use of energy, it is necessary to take the electric DSM as a resource development planning of power industry, energy planning and developmental planning of areas. TOU power price is one of the principal means for DSM. Therefore, the use of power price signals has become such a pressing needs, which to guide electric consumers take the reasonable structure and consumption so that electric power company make electric power load mild, achieve greater power efficiency and save electricity production investment. Considered the three interests of government, the power company and users, this thesis focus on studying the use of game theory to establish TOU pricing model, in which government set tariff levels, the power company determine the tariff structure and the level of supply, users determine the consumption.The main research and conclusions of this paper include: (1)Comparative analysis of the existing TOU pricing model as the basis for the study.(2)Use of Ramsey-Boiteux public goods pricing models,which developed from the marginal cost theory, to ensure that social welfare through price-cap regulation. In this method, power are considered as interaction products to decide its tariff levels,and those tariff levels are integrated to determine the level of tariff restrictions.(3)Modelling analysis. Based on price level of restraint,using game method, contolling the electricity load reasonably and considering green electric power competition, this method calculate TOU price, optimal power supply of power company and the consumption of users. Then, related issues of models are discussed.(4)Cases analysis. This paper designs relevant method to confirm unknown parameters of models,then, uses Matlab to simulate the case to show the method and steps for setting TOU price and certificate the feasibility and advantage of this method.(5)Present the correlative recommendations and measures to perfect the demand side TOU system of our country.The study of this paper use game theory to establish the demand side power pricing in the terminal of the supply and marketing chain of electric power, in order to solve the...
