This letter proposes a two-stage heuristic approach to reconfigure a radial distribution network in the least possible computational time. All the network switches are closed in the initial stage of the operation, and a sequential switch opening strategy is suggested to obtain a near-optimal radial configuration. In the subsequent stage, a pair of switches is selected from the radial network to exchange its ON/OFF status. A mathematical model, using bus injection to branch current matrix, is developed to choose a pair of switches with an objective to reduce the power loss in the network after each exchange operation. The proposed approach is tested on 33-bus, 69-bus, 84-bus, 136-bus, and 417-bus distribution networks, and the results confirm that the suggested methodology helps in achieving the best configuration of the radial distribution networks in a significantly low run-time.

一种简单快速的放射状配电网络重构启发式方法


这封信提出了一种两阶段启发式方法，以在尽可能少的计算时间内重新配置径向配电网络。所有网络交换机在运行的初始阶段都是关闭的，建议采用顺序开关打开策略以获得接近最佳的径向配置。在后续阶段，从径向网络中选择一对开关来交换其ON/OFF状态。开发了一种数学模型，使用总线注入分支电流矩阵来选择一对开关，其目的是减少每次交换操作后网络中的功率损耗。所提出的方法在 33 总线、69 总线、84 总线、136 总线和 417 总线配电网络上进行了测试，结果证实所提出的方法有助于实现径向配电网络的最佳配置。运行时间显着缩短。
