区域电力市场环境下省级电力公司竞价策略研究

Bidding Strategic Study for Provincial Electric Power Companies under Regional Market Environment

构建了一个省级电力公司购电费用数学模型。在区域电力市场规则的框架下,探讨了影响省级电力公司效益的市场行为及相关因素。其中包括年度发电合同电量、月度竞价交易电量、日前竞价交易电量三者的分配比例关系;负荷预测偏差;短期机组组合的安排。通过该模型分析以上因素对省级电力公司效益的影响程度及方式,并给出电力公司最优策略。

A power purchase cost mathematical model is established for provincial electric power companies.Under the regulatory framework of regional power market,this paper probes into the market behaviors and related factors influencing the benefits of provincial power companies,including the proportion among the three parts of electric power volume： annual contract,monthly bidding trade and day-ahead bidding trade,load forecast error,as well as short-term arrangement of unit commitment.Then the aforementioned model is applied to analyze how these factors influence the benefits of the provincial electric power companies.Finally,the paper proposes an optimal strategy for provincial electric power companies.
