摘要/Abstract

摘要：

基于配电网可靠性和网络重构方面的研究，提出了一种考虑配电网可靠性下的重构快速方法。首先通过对可靠性指标体系研究，确定以有功网络损耗（LOSS）、系统供电量不足（ENS）和平均供电可用率（ASAI）作为评价指标体系，并进行了归一化构建配电网多目标模型，运用判断矩阵法将多目标函数转化为新的单一目标函数，实现对配电网系统的重构优化快速计算。算法在重构后期引入可靠性评估，提高了配电网最优解的求解效率。通过IEEE69算例验证了新的配电网重构优化算法在获得全局最优解的同时，降低了计算时间，能有效解决复杂网络的重构优化问题。

关键词: 可靠性评估, 配电网重构, 有功网络损耗

Abstract:

Based on the research of the reliability of distribution network and the reconstruction of network,a new method was put forward to reconstruct the power grid reliability.Firstly,the evaluation index system was proposed,which included the active network LOSS (LOSS),lack of system power supply (ENS) and the average power supply availability (ASAI).A multi-objective model of distribution network was constructed by normalization,and the multi-objective function was transformed into a new single objective function by using the judgment matrix method,which realized fast calculation of power distribution network reconstruction and optimization.Through IEEE69 example verification,the optimization algorithm can obtain the global optimal solution and reduce the computational time at the same time,effectively solve the problem of the reconstruction of the complex network optimization.

Key words: reliability assessment, grid reconstruction, active network loss
