该重新配置算法开始于所有可操作的开关断开，并且在每一步，闭合导致目标函数增加最少的开关。目标函数被定义为增量损耗除以增量负荷服务。一个简化的损失公式被用来筛选候选开关，但一个完整的负载流后，每个实际开关关闭保持准确的损失和约束信息。回溯选项减轻了算法的贪婪搜索。该算法比其他方法花费更多的计算机时间，但它更准确地建模约束和控制动作。网络负载流用于提供损耗的下限。本文包括其他作者使用的几个测试系统的结果。
This reconfiguration algorithm starts with all operable switches open, and at each step, closes the switch that results in the least increase in the objective function. The objective function is defined as incremental losses divided by incremental load served. A simplified loss formula is used to screen candidate switches, but a full load flow after each actual switch closing maintains accurate loss and constraint information. A backtracking option mitigates the algorithm's greedy search. This algorithm takes more computer time than other methods, but it models constraints and control action more accurately. A network load flow is used to provide a lower bound on the losses. The paper includes results on several test systems used by other authors.
