摘要
建立公平的跨省区输电定价方法及合理的效益评估方法,为输电交易各方提供价格及经济信号,对交易方具有重要意义。基于改进后的潮流追踪法,构建了跨省区输电定价模型,使负荷不承担以本节点为首节点的线路的输电费,基于逆流追踪法明确与负荷对应的送电电源构建消费者剩余计算模型,精确评估跨省区输电效益,充分考虑了各方拓扑结构对物理潮流的影响,具有明确的物理意义。
It is very important to establish a fair and reasonable pricing and benefit estimation method for trans-province transmission, which can provide the information of price and economic signals for both sides of the traders. Based on the improved power flow tracing, a pricing model is established for trans-province transmission, which can make the load not undertake the transmission cost for the branch initiated from that load node. Then a consumer surplus calculation model is built by using the up-stream tracing method to define the feeding power source corresponding to the load,and the benefit of trans-province transmission is evaluated accurately, in which the influence of each trader＇ s topology on the physical flow is fully considered.
