高阻塞成本和新的阻塞模式，形成间歇性可再生能源发电，更有效地利用输电系统的需求。传输开关（TS）和可变阻抗串联FACTS设备是通过控制功率流来提供这种效率增益的两种技术。随着系统运营商开始使用这些工具，必须了解它们在规划和运营等各个阶段的相互依赖性。本文提出了一个最优潮流框架，结合FACTS和TS研究两种潮流控制技术之间的联系。RTS 96节点系统的仿真结果表明：1）通过利用TS和FACTS，可以实现大量的经济节约，超出每种技术的独立能力; 2）执行TS动作影响FACTS设备的最佳位置和设定点;和3）FACTS设备的操作影响TS动作的位置和频率。因此，必须承认这两种技术在规划和操作阶段的相互依赖性。如果不这样做，将导致经济效率低下，可以通过发电调度，TS和FACTS的共同优化来避免。
High congestion costs and new congestion patterns, formed by intermittent renewable generation, demand for more efficient utilization of the transmission system. Transmission switching (TS) and variable-impedance series FACTS devices are two technologies that provide such efficiency gains through controlling the power flows. As the system operators begin to utilize these tools, it is essential to understand the interdependence between them at various stages, such as planning and operation. This paper develops an optimal power flow framework that incorporates both FACTS and TS to study the link between the two power flow control technologies. The simulation results on an RTS 96-bus system suggest that: 1) substantial economic savings can be achieved through utilization of both TS and FACTS, beyond the independent capabilities of each technology; 2) performing TS actions affect the optimal location and set point of FACTS devices; and 3) operation of FACTS devices affect the location and frequency of TS actions. It is, thus, essential to acknowledge the interdependence between the two technologies both at the planning and operation stage. Failure to do so will lead to economic inefficiencies that can be avoided through co-optimization of generation dispatch, TS, and FACTS.
