基于网损分摊的两种潮流追踪法对比研究

Contrast and Research of Two Power Flow Tracking Methods Based on Loss Allocation

网损分摊的潮流追踪法按照追踪的方向或对象不同,可以分为顺流追踪和逆流追踪,但是这2种潮流追踪法有着各自不同的优缺点,在网损分摊的计算应用中有着不同的作用,现有的文献资料很少涉及2种追踪方法的比较研究。基于以上原因,对电力市场环境下网损分摊方法——潮流追踪法进行研究,通过对基于网损分摊的两种潮流追踪方法的简单介绍,对比分析两种潮流追踪方法的优点和不足,分别以少节点无损系统和少节点有损系统为例进行计算,结果表明两种潮流追踪方法的计算结果具有一致性,但应用范围不同,最后指出使用潮流追踪法时需要注意的问题,为指导电力市场交易提供一定的借鉴作用。

According to the different tracking direction or object,net allocation power flow can be divided into current tracking and adverse current tracking.But the two power flow tracking methods have the different advantages,disadvantages and have the different value in the loss allocation of the calculation and application.The existing literature material rarely involves the contrast and research of the two power flow tracking methods.Loss allocation power flow tracking methods are researched in the electric power market environment.Through the brief introduction to two kinds of power flow tracking methods based on the loss allocation methods,this paper contrasts and researches the advantages and disadvantages of the two power flow tracking methods.By taking few node lossless system and few nodes harm in system as example respectively,it is proved that the calculation results of the two power flow tracking methods are consistent,but the application scopes are different,finally the problems to be paid attention are pointed out,which can be referred to electric power market transactions.
