提出了一种配电网重构的快速支路交换算法.该方法中用近似网损替代精确网损,对每个联络开关依次进行对应环网的重构优化,根据最佳转移负荷的符号和大小确定环网的最大降损开关交换,避免了使用启发式规则,且在重构过程中无需进行潮流计算,从而显著提高了网络重构的计算速度.算例结果验证了该方法的正确性和快速性.

A QUICK BRANCH-EXCHANGE ALGORITHM FOR RECONFIGURATION OF DISTRIBUTION NETWORKS

A quick branch-exchange algorithm for reconfiguration of distribution network is proposed. Substituting actual network power losses by approximate power losses, the reconfiguration and optimization of corresponding loop network for each tie switch are conducted. According to the sign and magnitude of optimal transferred loads, the largest power loss reduction of the loop network from branch-exchange is determined, so it is avoided to use heuristic rules to reduce searching space and to calculate power flow in the course of network reconfiguration, thereby the calculation efficiency of network reconfiguration is evidently improved. The results of calculation example show that the proposed algorithm is correct and fast.
