摘　　要：随着输电网的逐步开放,人们越来越关心输电费用的分配问题,希望根据对线路的实际使用情况计费。在回顾了以往基于交易和基于直流潮流灵敏度分析的分配方案后,重点对几种基于潮流跟踪的分配方案进行了评述。Bialek跟踪法提出了潮流跟踪算法中一个重要原则———比例分配原则;Kirschen跟踪法引入domain,common,link的概念简化了系统,根据比例假设,将潮流跟踪的速度大大提高;基于电流的潮流跟踪对复电流的实部和虚部分别进行跟踪,最终再转化为功率的分布,它无需将网络的有功功率和无功功率解耦,无需将有损网络转换成无损网络。总结了有待解决的几个问题,表明以后的研究方向。This paper reviews the previous transmission pricing methods based on transaction and dc distribution factors. Several power flow tracing methods based on actual power flow are introduced. Bialek's tracing method gives an important tracing principle--proportional sharing principle. Based on the concepts of 'domain','common' and 'link', Kirschen's tracing method describes a state graph of the system and uses proportionality assumption to speed up tracing process. The current based tracing method is to trace real currents and imaginary currents separately and finally translate them into power allocation. In other tracing method, graph theory is used to decide downstream and upstream power flow tracing paths very fast and calculate efficiently.
