Abstract

The invention discloses an electricity clearing method and apparatus for adjusting the market supply and demand based on a residual supply index. The method comprises: residual supply indexes of a plurality of market subjects are obtained; if market power is employed, overall adjustment is carried out on power declared by power generation subjects and market needs of the power generation subjects;bidding functions of all market subjects in a competition clearing transaction part in a preset electricity market are adjusted and adjustment information is obtained; clearing of all market subjectsin the preset electricity market is carried out based on the adjustment information and market clearing information of a CTCP is obtained; on the basis of the market clearing information of the CTCP,matching of all market subjects in a forced price settlement part of the preset electricity market is calculated; and according to a clearing amount and a clearing price, settlement and clearing arecarried out on all market subjects. Therefore, the bidding electricity of the power generation subjects with the potential market power can be divided into two parts: a competition participation clearing transaction part and a forced price settlement part; and while the market supply and demand ratio is kept to be unchanged, full-competition market clearing is realized.

Description

technical field [0001] The invention relates to the technical field of electric power market, in particular to a method and device for clearing electric power to adjust market supply and demand based on a surplus supply index. Background technique [0002] The release of six supporting documents in the reform of the electric power system clarifies the pace of further market-oriented reform. Among them, one of the core goals of this round of power system reform is to establish a medium-to-long-term and spot power market system. The market model can be divided into two types: decentralized and centralized. At present, most provinces and regions across the country have started the process of power system reform, and most provinces and regions have opened up medium and long-term electricity trading, and some provinces and regions have included the construction of electricity spot markets in their reform roadmaps. [0003] The existing medium and long-term trading models are gen...
