摘　　要：提出了一种基于改进的混合遗传算法的配电网重构算法,在算法中使用可操作开关支路的整数编号的排列顺序来表示染色体,并通过译码器的设计来映射染色体所对应的辐射状网络结构,避免了产生不可行解的情况,大大提高了算法的运算效率。同时在算法中引入了局部寻优算子,改善了算法的局部寻优性能。算例结果表明本算法是高效可行的。This paper proposes an improved solution for distribution network reconfiguration based on a refined hybrid genetic algorithm. In the algorithm, the 'the integer permutation' encoding is adopted with each integer representing one controllable switch. A decoder is designed to decide the final network configuration corresponding every chromosome. A local search operator is combined with the genetic algorithm which improves the local optimal capability of the algorithm. The computational results on a tested system demonstrate the algorithm is feasible and efficient.
