Abstract

This paper suggests an improved method for usage allocation to individual generators in a deregulated power system. Based on solved load flow, the method converts power injections and line flows into real and imaginary current injections and flows. These currents are then represented independently as real and imaginary current networks. Since current networks are acyclic lossless networks, proportional sharing principle and graph theory is used to trace the relationship between current sources and current sinks. The contributions from each current source are finally translated into power contributions to each load, line flows and losses. IEEE 14-bus test system is used to illustrate the effectiveness of the method. Comparison of the results with previous methods is also given

一种用于解除管制的输电系统的改进的使用分配方法
本文提出了一种改进的电力系统中单个发电机的电量分配方法。该方法在求解负荷流的基础上,将功率注入和线路流转换为实电流注入和虚电流注入和虚电流注入。然后将这些电流分别表示为实电流网络和虚电流网络。由于电流网络是无环无损网络,因此利用比例共享原理和图论来跟踪电流源和电流汇之间的关系。每个电流源的贡献最终转化为对每个负载、线路流和损耗的功率贡献。用IEEE 14总线测试系统验证了该方法的有效性。并将计算结果与以往方法进行了比较
