| 摘要: |
| 提出了一种基于差分进化的配电网重构方法。采用基于十进制环状编码方法解决了二进制编码产生大量不可行解的问题。给出了十进制环状编码的变异、交叉和选择策略；提出了一种在计算的同时调整支路节点顺序的算法，解决了配电网重构后部分支路电流流向颠倒的问题。应用差分进化算法对IEEE 33节点网络进行配电网重构仿真，结果表明该方法能有效降低配电网损耗。 |

| Abstract: |
| Distribution network reconfiguration based on differential evolution algorithm is proposed，instead of cyclic binary coding，which adopts the cyclic decimal encoding method to avoid the problem of infeasible solutions. Its strategies of mutation，crossover and selection are given. An algorithm which adjusts branch node order while calculates is proposed to avoid the reverse branch current after reconfiguration. Simulative results of distribution network reconfiguration based on differential evolution algorithm for IEEE 33-bus system show that the network loss is effectively reduced. |
