ANIMPROVEDOPTIMALFLOWPATTERN ALGORITHM FOR DISTRIBUTION NETWORK RECONFIGURATION

本文提出了一个配电网络重构的改进最优流模式法（ＩＯＦＰ）。并用一个快速有效的单环网潮流算法求解最优流模式。本文考虑了网络重构的实际运行约束，如最大刀闸操作次数，支路过载等。经测试系统的验算表明，本文算法快速有效，可以用于实时环境。

An Improved Optimal flow Pattern(IOFP)algorithm for distribution network reconfigu-ration is presented in this paper.Voltage dependentload model is considered in this algorithm,and onlyone loadflow calculation is needed to determine whichswitch should opened.So the amount of calculationis reduced down to 50%while at the same time the ac-curacy is improved.Anovel single loop load flow algo-rthm is presented to determine the optimal flow. Lossreduction due to reconfiguration is estimated with asimple formula. Digital tests were carried out and the results showed that the IOFP algorithm is good and the calculation speed is very fast,it can be applied in a real time environment.
