Abstract

The invention provides a method for evaluating market power after power market transaction, and the method comprises the steps: comprehensively considering a market structure, and the market behaviors and market clearing results of all market participants according to the clearing result and historical transaction data of monthly concentrated competitive transaction of a power market, and judging whether there is a basis for enabling the market power from the market structure; whether the situation of manipulating the market price exists or not is judged according to market behaviors and market clearing results, and market subjects influencing the market price are judged through quantitative calculation. The evaluation method provided by the invention can effectively discover and quantitatively evaluate market performance behaviors in monthly concentrated competitive transactions of the Guangdong electricity market, so that an electricity market supervision mechanism can conveniently carry out market monitoring and maintain the market order; the method is beneficial for a market operation mechanism to specifically improve market design defects, improve market efficiency and promote market full competition, and has the advantages of comprehensive evaluation, simple operation, reliable result and the like.

Description

technical field [0001] The invention relates to the technical field of electric power market, in particular to a method for evaluating market power after transaction in the electric power market. Background technique [0002] At the current stage, my country's electricity market transactions are mainly medium and long-term transactions, mainly including annual transactions and monthly transactions. Among them, the relatively common monthly centralized competitive transactions adopt the organizational form of two-way quotations and uniform clearing of marginal prices, and there is only one transaction price in the overall market. In this type of monthly centralized competitive transactions, specific market entities may exercise market power through economic retention means, affect the unified clearing price, disrupt market order and seize illegitimate profits at the same time, resulting in a reduction in the efficiency of market resource allocation. [0003] In order to effe...
