如何在发电权交易中计及网损成本是保证交易合理、高效的重要问题之一.针对这一问题,分析比较了现有发电权交易模型的优缺点,提出了适合中长期交易的改进集中撮合交易模式.首先,运用最小二乘B系数法确定网损成本与交易电量之间的量化关系;然后,构建计及网损成本的社会效益最大化模型,通过求解该模型,确定发电权交易双方买入和卖出的总电量;最后,以此交易电量为约束,建立撮合交易的数学模型.以IEEE 30节点系统为例,对所提出的交易模式的特点进行了分析,分析结果验证了该模型的合理性和有效性.

How to consider transmission loss cost in generation right transaction is an important issue in ensuring transaction reasonability and effectiveness. To solve this problem, the advantages and disadvantages of the existing generation right transaction model are analyzed, and an improved centralized matchmaking transaction model is proposed to adapt to middle-and long-term transaction. First, the least squares B coefficient method is used to determine the quantitative relationship between transmission losses and transaction quantity. Then the social benefit maximization model considering transmission losses cost is developed, and by solving this model, the total generation of each seller and buyer is obtained. Finally, with the generation volume agreed on by each seller and buyer as constraints, a mathematical model for the matchmaking transaction is developed. An IEEE 30-node system is used as an example to analyze the characteristics of the proposed transaction model. The analysis results prove the rationality and efficiency of this model.
