A power market price difference contract electric quantity decomposition technology and a decomposition result comprehensive evaluation method

Abstract

The invention relates to a power market price difference contract electric quantity decomposition technology and a decomposition result comprehensive evaluation method. The method comprises the stepsthat annual contract electric quantity is decomposed according to a corresponding annual typical output curve; Decomposing monthly decomposed electric quantity to days through annual monthly decomposition and cross correction in combination with days and electricity consumption of each type of days within a month; On the basis, the daily contract electric quantity is decomposed to each time period, the decomposed electric quantity deviation caused by the maintenance plan is corrected based on a cross correction algorithm, and a financial settlement delivery curve for authorizing the price difference contract electric quantity at each time period is formed; And finally, establishing a post-evaluation index system of contract electric quantity decomposition, and evaluating a decomposition result from four aspects of risk, fairness, economy and rationality. The new electric power market contract electric quantity decomposition method and the post-evaluation model provided by the inventioncan provide a reasonable settlement basis for two parties of electricity generation and purchase, evaluate the advantages and disadvantages of the contract electric quantity decomposition method, andrealize the coordinated operation of the contract market and the spot market.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a power market price difference contract electricity decomposition technology and a comprehensive evaluation method for decomposition results. Background technique [0002] Since electric energy cannot be stored economically, medium and long-term contracts are equivalent to establishing a virtual inventory to lock the price of electric energy in advance to avoid the risk of electricity price fluctuations caused by the mismatch between supply and demand. At present, in countries that have implemented electricity market-oriented operations, such as the United States, the United Kingdom, and Australia, most of them use medium and long-term contracts (physical contracts or financial contracts) for large-scale electricity transactions. Existing studies have shown that the introduction of medium and long-term contracts can help reduce the use of market power by power companies to manipulat...
