提出了一种兼顾均匀性的配电网多目标重构方法。分析了不同均匀性网架结构下可靠性与网损的关系,给出了网架结构均匀性的评价指标。建立了兼顾均匀性的多目标配电网重构模型(distribution network reconfiguration based on system homogeneity,DSH),并采用改进多目标和声搜索算法来求解DSH模型。通过对IEEE 33节点测试系统的仿真分析,验证了DSH模型求解算法的有效性与合理性,给出了考虑可靠性和均匀性的配网重构问题的最优解集,供决策者根据实际情况选择。
Based on homogeneity, a new multi-object configuration method is proposed. To enhance the system reliability and homogeneity, a new multi-objective model is established. Then the relationship of reliability and feeder losses with different homogeneity is discussed, and an improved multi-objective harmony search algorithm is applied to the presented method. The test result by IEEE 33 bus system shows that the presented method is rational and effective, and the optimization solutions considering both system reliability and homogeneity are given so that the dispatchers can make choices according to the actual situation.
