Development of a hybrid UPFC-based solution for voltage SAG and harmonic mitigation in EV charging infrastructure in Uganda-a case study of KMC Jinja.

Abstract

This project focused on addressing power quality challenges at electric vehicle (EV) charging stations in Uganda, specifically voltage sags and harmonic distortions. The goal was to design and simulate a hybrid Unified Power Flow Controller (UPFC) sys tem to mitigate these issues. The project involved assessing power quality at selected EVcharging stations, designing a UPFC system and harmonic filters, and evaluating the system’s performance using MATLAB simulations. The results demonstrated that the hybrid UPFC system effectively maintained voltage levels within ±10% of the nominal voltage during disturbances and the Total Harmonic Distortion (THD) to acceptable lev els of below 8%, in accordance with IEEE standards.
