Identification and Location of FACTS Devices in Fourteen Bus System Using Matlab/Simulink

This paper deals with the modeling and simulation of location of FACTs devices in 14-bus system. Fixed Capacitor Thyristor- Controlled Reactor (FC-TCR), Thyristor-Controlled Series Compensator (TCSC) and Unified Power Flow Controller (UPFC) are included in 14-bus system to improve the bus voltages and powers. The voltage sag is created by adding an extra load at the receiving end. This voltage sag is compensated by using FACTS devices like SVC using FC-TCR, TCSC and UPFC. Improvement in the voltage and power are studied using simulation results.
