Application of static synchronous compensator (STATCOM) to enhance voltage profile in IEEE standard 5 bus transmission system

Abstract

Background/Objectives: This paper presents implementation of Static Synchronous Compensator (STATCOM) which can control reactive power through transmission lines in an IEEE standard 5 bus system to meet constraints on bus voltage magnitude, thermal limits and power factor. Methods/Statistical Analysis: This is made possible by appropriately controlling compensation current of shunt compensator. Findings: Simulation results on performance of STATCOM are studied in MATLAB/SIMULINK and validated the effectiveness of the controller. The results show reduction in losses, improvement in power factor and improvement in bus voltage profile are obtained with STATCOM. Application/Improvements: Power flow through the transmission line had improved from 0.014 p.u. to 0.154 p.u.
