柔性交流输电系统（FACTS）控制器提供了一种有效的手段，以提高网络的功率传输能力。然而，在何种程度上FACTS控制器可以提高可用传输能力（ATC）取决于它在系统中的最佳位置。本文提出了结构保持能量裕度的灵敏度分析的FACTS控制器的控制参数，他们在网络中的最佳配置。两种类型的FACTS控制器，即静止同步补偿器（STATCOM）和统一潮流控制器（UPFC）已被考虑。混合的方法，结合结构保持和时域仿真方法，已被用来计算动态ATC在这些控制器的存在和它们对动态ATC的影响进行了分析。STATCOM和UPFC贡献的势能也被包含在结构保持能量函数中，以包括它们对暂态稳定性的影响。所提出的方法已在39节点新英格兰系统和一个实际的246节点印度系统上进行了测试。
Flexible AC Transmission System (FACTS) controllers offer an effective means to enhance the power transfer capability of the network. However, the extent to which a FACTS controller can enhance Available Transfer Capability (ATC) depends on its optimal location in the system. This paper has proposed sensitivity analysis of structure preserving energy margin with respect to the control parameters of FACTS controllers for their optimal placement in the network. Two types of FACTS controllers, viz. Static Synchronous Compensator (STATCOM) and Unified Power Flow Controllers (UPFC) have been considered. The hybrid approach, combining a structure preserving and a time domain simulation method, has been utilized to compute the dynamic ATC in presence of these controllers and their impact on dynamic ATC has been analyzed. The potential energy, contributed by the STATCOM and the UPFC, has also been included in the structure preserving energy function to include their influence on transient stability. The proposed method has been tested on 39-bus New England system and a practical 246-bus Indian system.
