标题： On Loss-Minimal Radial Topologies in MV Systems

摘要： 配电系统重构（DSR）是指通过开关操作来优化配电网的拓扑结构。 开关操作是配电系统运营商可用的自由度之一，例如用于管理计划内和计划外的停电。 DSR 是一个 NP 难组合问题。 找到良好的甚至最优的解决方案在计算上代价高昂。 虽然输电和高压电网通常以网状状态运行，但中压配电系统通常以辐射网络的形式运行，尽管支持网状运行。 这提高了系统的韧性，因为故障可以更容易地被隔离，从而保持系统的其余部分正常运行，并尽量减少对客户的影响。 我们提出了一种交流 DSR 公式，并将其与文献中的常见公式进行了基准测试。 我们的结果显示，额外的无环约束可以显著提高求解器性能。 显示英文摘要

摘要： Distribution system reconfiguration (DSR) means optimizing the topology of a distribution grid using switching actions. Switching actions are a degrees of freedom available to distribution system operators, e.g. to manage planned and unplanned outages. DSR is a NP-hard combinatorial problem. Finding good or even optimal solutions is computationally expensive. While transmission and high-voltage grids are generally operated in a meshed state, MV distribution systems are commonly operated as radial networks even though meshed operation would be supported. This improves resilience because faults can be isolated more easily keeping the rest of the system operational and minimizing impact on customers. We propose an AC DSR formulation and benchmark it against a common formulation from the literature. Our results indicate that additional acyclicity constraints can significantly improve solver performance.
