Research On The Formation Mechanism Of Electricity Price Under Reformation Background Of Electric Power System

Power Industry is the basic of our national economy. In the planned economy era, we’ve built up a monopoly model of development, transmission, distribution, and sales, which was strictly controlled by the government. But with the development of economy, this model gradually shows its disadvantages. The official release in 2002 of reformation of electric power market indicates we are entering the most profound reform ever, and the aim is to achieve the separation of power net and power plant, Bidding online thus to urge price setting and releasing by market. The core of this reformation is to break the monopoly model by market competition and improve the rational distribution of power resource and the healthy development of power market.But so far, the price system of power market still remains many problems, also many restrictions in price setting. In order to better study the price setting mechanism in power market, this paper made a deep research of the situation of domestic and foreign power grid price setting and also by analyzing the theoretical basis of price formation, the constitutive mechanism of price and its particularity to find price formation mechanism and methods, thus analyze related factors to price. Meanwhile, this paper also analyzes and compares two methods of price setting-accounting cost and marginal cost. Take Zhejiang Province and Hangzhou electric company actual motion as an example, analyzes current on-grid price sales price and large users direct power-purchase models’ formation process and implementation status to indicate and study the process of our national’s reformation of power. This paper finally researches the design of price formation mechanism in three parts which are on-grid、transmission and distribution price, sales price. During the design stage of on-grid price mechanism mainly study two-part price and its design in fully competition. During the stage of transmission and distribution price mechanism mainly study the price mechanism after assets supervision and the formation mechanism under the power market transaction mainly by contract. During the stage of sales price mechanism this paper mainly studies in the needs response mechanism area.
