考虑交易成本的区域市场撮合交易模型

APPLICATION OF HIGH-LOW MATCH METHODS TO REGIONAL ELECTRICITY MARKET CONSIDERING TRANSACTION COSTS

组织区域电力交易、优化大区资源配置已成为当前电力工业改革的重点。而设计实用的区域交易模型必须解决两大难题:首先,需设计科学的交易机制,充分保证各省电价相对平稳,以协调各省经济的均衡发展,实现电力改革与社会主义市场经济的和谐发展;其次,必须公平、妥善解决跨省交易输电费用等实际问题。作者在充分研究上述因素后,建立了考虑跨省输电费用等交易成本损耗的数学模型,并通过分析具体算例的结果阐述了该模型在促进交易、稳定市场及推动改革方面的积极作用和意义。

At present there are two key tasks in power industry reformation, i.e., to organize the regional power transaction and optimize the assets allocation in larger areas. Two difficult problems should be solved during designing practicable regional transaction model, one of them is to design a rational transaction mechanism to ensure the electricity prices of different provinces in the region are relatively stable, so the balanced economic development of these provinces can be coordinated to implement the harmonious development in both power industry reform and social market economy; and the another one is that some practical problems, such as the power transmission cost for trans-provincial transaction, should be impartially and properly solved. On the basis of detailed research on above-mentioned problems, the authors built up a mathematical model for high-low match method in which the transaction costs of trans-provincial power transmission are considered. By use of modified IEEE 57-bus system, the results of numerical examples reveal the positive signification of the proposed model in promoting power transaction and stabilizing electricity market as well as giving impetus to power industry reformation.
