Simulation of Location of TCSC and UPFC in Fourteen Bus System Using Matlab / Simulink

This paper presents the modeling and simulation of 14-bus system using TCSC and UPFC. Thyristor Controlled Series Compensator (TCSC) and Unified Power Flow Controller (UPFC) are included in 14-bus system to improve the power quality of the power system. The voltage sag is created by adding an extra load at the receiving end. This sag is compensated by using FACTS devices like TCSC and UPFC. Improvement in the voltage and power are presented using simulation studies.
