Abstract: Increasing power demands leads to the condition were transmission are heavily loaded, thus power system stability become concern. This paper studies the effect of UPFC on power system stability. For heavy fault condition, the machines in a stable power system initially oscillate and then settle at the stable equilibrium point where the transient energy is zero. This paper utilizes the rate of dissipation of transient energy as a measure of system oscillation damping. This concept is used to determine the additional damping provided by power system stabilizer and facts device SSSC and UPFC. This technique is then studied with help of MATLAB Stimulant for various condition with help of single machine infinite bus system(SMIB).
