Power Quality Improvement for Thirty Bus System Using UPFC and TCSC

This work deals with power quality improvement by using FACTS devices. When the reactive power of the load is changing continuously, a suitable fast response compensator is needed. Unified Power Flow Controller and Thyristor Controller Series Capacitor are two such compensators belonging to FACTS devices which are used in this work. Models for the UPFC and TCSC are developed using MATLAB Simulink. The simulation results for thirty bus system with UPFC and TCSC are presented.
