本文提出了基于注入移位因子的线性建模的各种类型的串联灵活交流输电系统（FACTS）的直流潮流框架内的设备。所提出的模型允许FACTS设备被正确地集成在当前的操作和规划软件工具，这是利用FACTS技术提供的潮流能力的关键。虽然最近的文献已经试图开发FACTS设备的线性模型，现有的模型不能准确地反映许多FACTS设备的实际工作范围。与现有的模型相比，这里提出的建模方法反映了每种类型的串联FACTS设备在调整输电线路电抗的操作原理。通过数学推导，建立了FACTS运行的线性约束条件，并利用这些线性约束条件建立了电力系统运行模型。制定的问题，然后通过模拟研究分析各种测试系统。结果突出了基于DC的操作模型中的线性FACTS建模提供的显著计算效率改进。
This paper presents injection‐shift‐factor‐based linear modelling for various types of series flexible ac transmission system (FACTS) devices within the DC power flow framework. The presented models allow FACTS devices to be properly integrated in current operation and planning software tools, which is key to harnessing the power flow capabilities provided by FACTS technology. Although recent literature has attempted to develop linear models for FACTS devices, the existing models do not accurately reflect the actual operating range for many FACTS devices. Compared to the existing models, the modelling approach presented here reflects the principle of operation of each type of series FACTS device in adjusting transmission line reactance. Through mathematical derivation, linear constraints for FACTS operation are formulated, which are used to formulate power system operation models. The formulated problems are then analysed through simulation studies on various test systems. The results highlight the significant computational efficiency improvements provided by linear FACTS modelling in DC‐based operation models.
