Research On The Regulation Model Of Transmission And Distribution Price Based On Pricing Capping

Electricity price reform is the core of the reformation of power market. The special status of transmission and distribution network in the power system and it's strong natural monopoly properties lead to the top priority of develop a reasonable transmission and distribution price. However, there are no independent pricing mechanism in our country, and the so-called transmission and distribution price is received by terminal sales price minus the generation price, this makes the percentage of price ratio in sales price less than 30%, the price ratio is in a serious imbalanced. The problems of transmission and distribution price seriously hinder the process of Electricity price reform, and become a major bottleneck of the reformation of power market. Therefore, it is urgent for us to study a regulation model of transmission and distribution price which is consistent with our national conditions.At present, it is hot to study the incentive regulation, especially the price cap regulation. However, the application of price cap regulation in power industry is rather difficult, and it's effectiveness is questioned. In this paper, peak-load pricing which is suitable for power industry's time and technical characteristics is used to examine the availability of price cap regulation, and the conclusions support the price cap regulation favorably. In particular, in the regulation mode of "RPI-X" , the power enterprise will choose the optimal price structure actively, this structure will bring maximize profits to enterprise, and improve the overall social welfare at the same time.It is inappropriate of applying the "RPI-X" regulation model directly. Therefore, this paper designed a set of feasible incentive mechanism to induce enterprises to report costs honestly, and so as to formulate the best price of transmission and distribution and then build the new price regulation model. The model concerns about efficiency coefficient, investment factor and quality factor, reflects the principles of incentive efficiency, dynamic efficiency and service efficiency, these make the model not only has the function of encouraging transmission and distribution enterprises to raise the productivity, maintain and improve the quality of services, but also has the role of promoting network investment and protecting consumer's benefits.
