Evaluation and Improvement of Line Utilization using FACTS Devices

Abstract

Flexible AC Transmission Systems, also popularly known as FACTS devices, are static power-electronic instruments used in AC transmission networks to escalate power transfer capability, make systems more stable, and increase the controllability of the networks through series shunt compensation. In recent times, the popularity of FACTS devices and their usage have increased, mainly in developed countries. This increase in the use of FACTS devices has been very beneficial for the overall performance of the system. This paper contains the basic concept and knowledge of FACTS devices, which are used in the power system. The paper gives information about the different FACTS devices that can be used in the generation, transmission, and distribution systems in order to perform certain tasks and the various types of devices under them. The paper also includes the simulation of a given system in MATLAB software in order to compensate for or decrease the current limit by using the FACTS device at a certain point on a transmission line. The paper also gives us an idea of how the different types of FACTS devices can be used and their current use in the industrial area or in the power system, i.e., their impact on the modern industrial and power sectors
