输电拓扑控制（线路切换）目前是由独立系统运营商（ISO）控制室人员通过手动和临时行动来实施的，这些人员依赖于过去的经验以及与各种拥堵模式相关的线路断开的固定数据集。我们之前的工作利用直流经济调度问题解决方案中的灵敏度信息来开发拓扑控制算法，这些算法显著提高了操作员选择有希望断开/闭合的线路的能力。然而，在控制室中，算法必须依赖基于交流的潮流工具来确保物理网络中的可行性。考虑到在运行环境中必须满足的计算时间限制，在基于直流的拓扑控制算法和对提议的拓扑控制行动进行交流潮流验证之间进行迭代在大型系统中可能变得难以处理。在本文中，我们展示了直接依赖我们所开发的基于交流的拓扑控制算法的实际系统规模计算结果。特别是，我们讨论了一个关于PJM系统三周历史数据的案例研究，其中展示了基于交流的拓扑控制解决方案，并与相应的基于直流的解决方案进行了比较。
Transmission topology control (line switching) is currently practiced with manual and ad-hoc based actions by ISO control room personnel who rely on a combination of past experience and a fixed data set of line openings linked to various congestion patterns. Our previous work used sensitivity information from the solution of a DC economic dispatch problem to develop topology control algorithms that significantly improve the operators ability to select promising lines to open/close. In control rooms, however, algorithms must rely on AC-based power flow tools to ensure feasibility in the physical network. Considering the computational time constraints that must be met in an operational setting, iterating between DC-based topology control algorithms and AC power flow validation of proposed topology control actions may become intractable in large systems. In this paper we present real system size computational results relying directly on AC-based topology control algorithms that we have developed. In particular, we discuss a case study on three historical weeks of PJM system data where AC-based topology control solutions are presented and compared to the corresponding DC-based solutions.
