适用于多电源配电网潮流计算的前推回代方法

摘要

In this paper,an improved back/forward sweep method is proposed for the power flow in distribution network. Based on the traditional back/forward sweep method for the power flow calculation,the proposed method transforms the network with random numbers into a network in line with the numbering rule of the traditional back/forward sweep meth-od by using graph theory,and uses the traditional back/forward sweep method for the power flow calculation.The pro-posed algorithm is not only suitable for the single-power network,but also for the multi-power distribution network.In the multi-power distribution network,the network can be decomposed into multiple single networks.And because there is no effect between each network,parallel computing can be realized.A numerical example analysis is carried out on a typical 3-feeder 16-node system,which proves the feasibility of the proposed algorithm.%本文提出了一种改进的配电网潮流前推回代算法.在传统的前推回代潮流计算方法的基础上,利用图论的思想,将随机编号的网络转化为符合传统前推回代潮流计算编号规则的网络,进而利用传统前推回代潮流计算方法进行潮流计算.该算法不仅适用于单电源网络,同样适用于多电源配电网络.在多电源网络中,可以将网络分解成多个单独的网络,由于每个网络之间没有影响,可以并行运算.利用典型的3馈线16节点系统进行算例分析,证明了算法的可行性.
