配电网网络重构是配电系统极为重要的优化手段.以配电网网损最低为目标函数,结合约束条件确定配电网静态重构的数学模型,提出基于环路编码、分环替代的策略对配电网重构问题进行求解,最后结合IEEE-33节点算例,证明提出的算法,在降低搜索空间,提高寻优成功率和增加寻优效率上都有突出表现.(Distribution network reconfiguration is a very important means of optimization in distribution system. Taking the minimum loss of distribution network as the objective function and combining constraints to determine the mathematical model of distribution network static reconfiguration, a strategy based on loop coding and loop replacement is proposed to solve the problem of distribution network reconfiguration. Finally, combined with IEEE-33 node example, the algorithm is proved to reduce the search space and improve the success rate of optimization. It has outstanding performance in increasing the efficiency of optimization.)
