Abstract


Since the nineties of the last century,the market-oriented reform of power industry has been developed in full swing all over the world. in recent years, China has also begun to explore the road of reform. As the final link of the electricity price’s formation, the success of the market-oriented reform in sales price plays an irreplaceable role in helping optimize electric power resources and adjusting interest relations. Therefore, the sales price reform is more urgent and realistic. With the gradual deepening in the sales electricity price reform, the current sales price system has made considerable progress. But there exists the gap between the electricity prices whether decided by the government regulation or by the marketization. In the new round of electricity price reform, the key to the success reform is to stably transfer sales electricity price from the government regulation to the market-determined.This paper studies the policy adjustment of electricity price in the context of market-oriented reform. Firstly, from the perspectives of the monopoly and publicity of the power industry, it introduces a variety of methods in pricing, describes the development of the price adjustment in various fields, then pointes out the lack of the price adjustment theory in the study area, after analyzing the China’s current situation of power industry reform, and puts forward the core of the new round of sales reforms.Secondly, This article①considers the sensitivity of the basic industry price and maximizing the social welfare, combining with the double targets of stage and whole optimization, and designs the static and dynamic model of sales electricity price basing on the nonlinear programming theory and the optimum control theory, making the policy-type adjustment on the electricity price which is both basic fixed (one side is present electricity price ,the other is marketability electricity price ), and uses the Kuhn-Tucker theorem and the Hamilton method solves the model;②In guarantees the stable transition of electricity price,it divides the power consumer into seven kinds, taking overall level of policy-type adjustment electricity price during every periods as the datum, and consolidate the various characteristics of the user’s own. According to the actual situation, we make the amendment to adjust the line of policy considering the stability adjustment, the profit of electric enterprises and the social overall welfare, and other multi-factors. In order to ensure feasibility and stability of the electricity price reform, we also subdivide, finely tune, prove and feedback on the trend of reforming wholly.Finally, this text combines the relations of 2007 Hunan Province power consuming data, using design emulation regard as example through MATLAB software to analyze. The result shows: the static and dynamic model which designed in this text can realize the effective smooth transition of the price of electricity, and dynamic adjustment strategy on the basis of the optimal control can utilize the electric power resource more effectively and fully increase the social whole welfare, and categories of policy adjustment mechanism for the user according to dynamic adjustment model can run effectively under meeting various restraint terms.
