Z-BUS法网损分摊的比例法调整

Pro Rata Adjustment of Z-Bus Loss Allocation

在联营模式下,Z-BUS网损分摊方法能将系统的损耗自然分配到系统的各个节点上,可以反映系统的传输线参数和网络拓扑结构对网损的影响,是一种具有较好应用前景的网损分摊方法。但Z-BUS法对发电机节点损耗份额分摊过大,需要调整。对此提出用比例法调整Z-BUS法的分摊结果,减少发电机节点分摊的网损份额,并以IEEE-14节点网络为例进行仿真计算,和其他几种分摊方法进行比较分析,结果表明该方法具有合理性。

The Z-Bus loss allocation can lead a natural division of system losses among the network buses in the context of power pool market,and it also can reflect transmission lines parameters and the network topology.So it is one of prospective loss allocation methods.But the losses assigned to the generation buses are always much greater than that of load buses,so it is necessary to regulate the calculated loss.A method of using pro rata method to adjust the calculated loss is introduced in this paper.The simulation on IEEE14-bus network and the comparisons with several other loss allocation methods prove that it is a fair and reasonable loss allocation method.
