| 摘要: |
| 针对传统的含有分布式电源的配电网重构算法所存在的寻优速度和最终解的质量难以兼顾的问题，提出一种基于功率矩和邻域搜索的配电网两层重构算法。利用功率矩算法对各环路进行第一层重构优化，确定开断支路集，在此基础上采用具有方向的邻域搜索算法进行第二层重构。通过对当前解点的邻域搜索获取更优的解点位置，直至目标函数值不再下降，从而得到最终的重构方案。含有分布式电源的IEEE 33和IEEE 69节点典型测试系统的仿真结果验证了所提算法的有效性。 |

| Abstract: |
| Since the traditional reconfiguration algorithm of distribution network with distributed generations could not easily balance the searching speed and the quality of final solution, a two-level reconfiguration algorithm based on power moment and neighbourhood searching is proposed. The power moment algorithm is applied in the first level reconfiguration optimization to determine the open-branch set, based on which, the directional neighbourhood searching algorithm is applied in the second level to obtain the better solution adjacent to current solution until the value of objective function stops falling, which means the final reconfiguration scheme is found. The simulative results for typical test systems with distributed generations, i. e. IEEE 33-bus and IEEE 69-bus distribution systems, verify the effectiveness of the proposed algorithm. |
