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.
