An Optimal FACTS Device Allocation for Improving the Power Loss Factors in IEEE 9 Bus System

Abstract This paper deals with power quality improvement by using Unified Power Flow Controller (UPFC), Static Synchronous Series Compensator (SSSC) and Second Generation of FACTS Static Compensator (STATCOM) according to change of the reactive and real power of the load, a suitable high response compensator is needed. UPFC, (Thyristor controlled tap changer) TCTC, (Thyristor Controlled Series Capacitor) TCSC, SSSC, STATCOM and SVC are the compensators belonging to FACTS devices. this paper used UPFC (Unified Power Flow Controller), STATCOM (Static Compensator) and static synchronous Series compensator (SSSC). there are three such compensators belonging to FACTS devices. Models for the UPFC, SSSC, and STATCOM are analysis using MATLAB Simulink. The simulation results of nine bus system with UPFC, SSSC, and STATCOM are presented. MATLAB codes are utilized for the implementation of the three FACTS devices in the Newton – Raphson algorithm. Power flow control was evaluated for nine bus system.
