Abstract


This research presents an optimal power flow control method for the Katampe 330kV Transmission System using a Phase Shift Transformer (PST). Power transmission systems often experience unequal power flow, affecting power quality in terms of reactive power, active power, and voltage profile. The study employs Newton-Raphson’s power flow algorithm, PID control, and Particle Swarm Optimization (PSO) to optimize PST parameters and improve system performance. MATLAB R2021a simulations demonstrate significant improvements in real and reactive power losses across IEEE test networks (16, 33, and 69 Bus systems). The results show reductions in real power losses by 2.94%, 35.02%, and 53.88%, while reactive power losses improved by 1.99%, 24.28%, and 13.82%, respectively, after reconfiguration. These findings confirm the effectiveness of PST in enhancing power flow control and system efficiency.
