The Flexible AC Transmission System (FACTS) plays a vital role in power system performance enhancement. They attributes to accomplish faster and having an answer for many issues in power system study. With regards to this, a particle swarm optimization (PSO) algorithm is implemented so that to design the coordinated parameters of static VAR compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC). With behavioral nonlinearities of the power system, linear methods cannot be used to design coordinated parameters of controllers. Simulation is carried out on IEEE-14 bus system with help of MATLAB. PSO applied here is built on searching the values of L and C of SVC, then one can achieve desired and fine coordination. PSO is available with few modification, as change in PSO range & number, difference in selection criteria technique, control technique etc., with due respect to normalize PSO. The results are compared and found that coordination of FACTS devices with each other promises the efficiency of the suggested method for revamping Power flows. When function of TCSC is impelled by some curb, adjustable SVC can apply additional support to upgrade the gross performance.
