    摘要:

    提出一种基于启发式规则与和声搜索算法的配电网经济性重构方法.首先,根据配电网重构网络拓扑要求及和声搜索算法的特点,采用基于重构环解的和声向量编码方式,通过构建重构环特殊支路组、设定支路断开原则避免不可行解的产生;然后,以网损最小为目标分析初始网络,利用启发式规则将〖CS0,128,128,127〗各重构环搜索范围压缩到最有可能的有效解范围之中;最后,利用和声搜索算法在有效解范围中全局寻优.该方法显著减少了候选解数目,能够快速搜索到全局最优解,且搜索性能不随网络规模的扩大而变差.IEEE典型算例的仿真结果验证了本文方法的正确性和有效性.

    Abstract:

    A distribution network reconfiguration algorithm based on heuristic rules and harmony search algorithm (HSA) was proposed. At first, the codification strategy based on the reconstruction loops was adopted according to the characteristics of distribution network reconfiguration and HSA. Then, several special branch groups were constructed and several disconnecting rules were set to avoid the infeasible solutions. Furthermore, the initial network was analyzed with the objective function for the minimization of power loss, and the effective search space of each loop was shrunk by using heuristic rules. Finally, the harmony search algorithm was used to search the global optimal solution. Using the proposed method, the number of candidate solutions can be reduced greatly, the optimal solution can be achieved rapidly, and the search performance will not be worse with the expansion of the network. The simulation results of IEEE typical examples have verified the feasibility and effectiveness of the proposed algorithm.
