Discussion On Wholesale Competition Regional Electricity Market And Transaction Strategies Of Power Supply Company

The worldwide reform of power industry has been developing rapidily, whose relative problems become research hot spots. Nowadays, the experiments and constructions are promoted energetically in China, which make operational patterns, biding model, and risk-dealing strategy of reginional electricity market need immediate solution.According to the different degrees of monopolizing, competiting, and selectiong in such sections as generation, transmission, distribution and supplyment, the power markets fall into the following three operational patterns: single-buyer, wholesale competition, and retail competition. The operational patterns is intimately important the success of electricity markt. Because of lacking competition in opening purchasing side, the market efficiency is discounted. Meanwhile, the retail competition mode need stable transmission and distribution system structure, advanced communication network, perfect financial and regulations supports, and widespread reform of metering system, all which can't be accomplished in short term. Aim to regional power market experiment situation of our nation, this paper explores the wholesale competition operation mode in regional power market.Under the wholesale competition operation mode, the distribution company takes part in market competition as an independent economic entity, facing the problem to achieve the maximal profit. This paper exploits two fields: the general mode of competitive bargain electricity market, and trade strategies Of distribution companies. Finally, some important results are obtained. The contents studied include: a) the general mode of wholesale competition electricity market and bargain purchasing economic analysis of distribution company; b) study on bargain biding strategy of distribution company in spot market; c) exploration of competitive bargain mode of regional electricity market in China; d) application of Financial Derivatives in electricity market; e) distribution companies' optimal purchasing power assignment in every level electricity market.In begin, the running mode of worldwide power industry, the reform developing status and trend in China are introduced in brief, then, the trade strategy problem of generation company and supply company analyzed, including research methods, components, and biding strategies under various market ruled, finally, the research status and trend are summarized.Secondly, this paper gives a brief introduction on wholesale competitionelectricity market. According to the state and tendency of electricity market, the functions of the distribution company in electricity market are summed up and operation cost and profit contribution manner are analyzed, on which the strategies and behaviors of the distribution company are researched, thus establishing the base for studying the optimal purchasing electricity strategy of the distribution company.According to the development situation of regional electricity market in China, the necessity and practicability of promoting the wholesle competition mode in regional electricity market are analyzed. In China, distribution companies has formed a relatively independent operation system in last experience, thus setting up a foundation of both realizing regional electricity market and competitive bargain operation mode on generation and distribution sides. Therefore, it is necessary and practicable to implement wholesale competition operation mode in some regional electricity market with necessary conditions. Considering the two basic modes of regional electricity market, uniform electricity market and layered electricity market, this paper researches respectively the competitive bargain operation mode, including basic thoughts, market entities and operation mechanism, and trade types.In this paper, the major market rules and trasaction mode are proposed, and establishes a trade mechanism and resolution algorithm adopting time-division biding rule and uniform market clearance price under wholesale competition mode in uniform regional electricity...
