The transmission line transfer capability and power system stability are greatly affected by the low frequency electromechanical oscillations.

However, the capability of Flexible AC Transmission System (FACTS) controllers, such as Static Synchronous Series Compensators (SSSCs) and Unified Power Flow Controllers (UPFCs), has been explored and proven. This paper investigates and compares the dynamic performance of conventional and Adaptive Neuro-Fuzzy Inference System (ANFIS) based PSS and SSSC controllers applied in a two-area power system. The time domain simulation results, carried out in Matlab / Simulink platform, of the two-area power system subjected to different operating conditions, validate the efficiency of the proposed robust and simple approach with very good dynamic responses. The results demonstrate that the ANFIS based SSSC controllers show good damping performance characteristics in terms of both reduced amplitudes and settling times of oscillations compared to ANFIS based PSS controllers.

Abstract
The transmission line transfer capability and power system stability are greatly affected by the low frequency electromechanical oscillations. The conventional approach to damp these oscillations is by the use of Power System Stabilizers (PSSs). However, the capability of Flexible AC Transmission System (FACTS) controllers, such as Static Synchronous Series Compensators (SSSCs) and Unified Power Flow Controllers (UPFCs), has been explored and proven. This paper investigates and compares the dynamic performance of conventional and Adaptive Neuro-Fuzzy Inference System (ANFIS) based PSS and SSSC controllers applied in a two-area power system. The time domain simulation results, carried out in Matlab / Simulink platform, of the two-area power system subjected to different operating conditions, validate the efficiency of the proposed robust and simple approach with very good dynamic responses. The results demonstrate that the ANFIS based SSSC controllers show good damping performance characteristics in terms of both reduced amplitudes and settling times of oscillations compared to ANFIS based PSS controllers.
