This paper is about the improvement of system stability, reliability and power transfer of a power system using FACTS devices like SVC and UPFC. In this work, small-signal stability analysis is done on an IEEE 14 Bus System by considering it as single-machine infinite-bus (SMIB) system. The improvement of system stability using AVR, PSS and FACTS devices like SVC and UPFC are analytically verified using synchronizing torque and damping torque coefficients. The examination of each category is done with the help of MATLAB simulation software. From the results, it is proved that addition of FACTS devices helps in improving the stability of the power system than other compensators. It is also found that, among the FACTS controllers, the UPFC outplays other controllers in terms of increased rotor angle stability, power transfer and damping of oscillations.
