Research On Formation Mechanism Of Trans-regional And Trans-provincial Transmission Tariff In China

Reverse distribution of energy resources and the demand of our country determines the importance of cross provincial transmission as a means of optimizing the allocation of resources.Reasonable trans-regional and trans-provincial transmission price formation mechanism of transmission can not only guarantee the transmission cost recovery,but also lead to the power of investment and a wide range of important energy resource allocation optimization.The formation mechanism of transmission price includes transmission business regulation model,pricing method,pricing method and pricing method.On the basis of "transmission and distribution price management procedures","on further reform of the electric power system a number of opinions(in 2015 No.9)article" and "on the transmission and distribution price reform and the implementation of opinions",drawing on international experience,combined with China's 2020 trans-regional and trans-provincial transmission project planning,the formation mechanism of trans-regional and trans-provincial transmission price was studied and designed,mainly include:1)The research on the formation mechanism of transmission price in special transmission project.According to the power transmission grid structure,the special transmission project can be devided into point-to-net and net-to-net.This article discussed the power flow characteristic and price signal should be provide.In the form of pricing,the paper discusses the selection of one-part tariff and two-part tariff.As the price checking,first the annual allowed income was caculated,then the contrast and analysis was introduced by different ways.Finally the suitable mode was decided.The pricing method is based on stamp and MW-mile,consist of who and how many to bear.In accordance with the above ideas,this paper calculates and analyzes the transmission price of some special power transmission projects.2)The research on the formation mechanism of the common network transmission price.The power flow characteristics and price signals should be provided were cleared based on 2020 trans regional and trans provincial transmission network planning.In the price form and price checking,the rationality of using two parts tariff and uniform price was disscussed.Under the price signals should be provided,the transmission price is determined by accounting cost method and marginal cost method,and it's validity was verified by a numerical example.Finally,the distribution ratio of the generation side and the load side is calculated and the rationality is analyzed.
