Comparative Study of Traditional Devices and FACTS Controller for Enhancing the Transient Stability Margin

Instead of transmission lines expansion or building new substations in our present transmission system, the proper installation of FACTS (Flexible AC Transmission Systems) seems to be a promising strategy to support transient stability and increasing power demand. This paper narrates a correlative performance of traditional devices (AVR, TG, and PSS) with series FACTS controller on electric power network. Here, IEEE-14 bus system is considered to be the benchmark of the power network. This proposed approach is implemented with the power system analysis toolkit (PSAT) software and is applied to small case studies, IEEE 14-Bus. For the performance analysis the Eigen value analysis and time domain simulation results are compared for result validation. Results revealed that FACTS controller improve better stability as compared to other conventional used devices.
