Abstract:
This thesis explores the rapid integration of electric vehicles and the growing
adoption of solar energy. This has brought new challenges in the operation of
unbalanced power distribution systems, including increased energy losses, voltage
imbalance and environmental impact. This research presents a hybrid priori
optimization framework to address these issues, to reduce real and reactive power
losses, voltage deviations, pressure imbalance index, and carbon dioxide emissions. All
simulation results in all case studies show that case 16 gives the lowest objective
function value. It represents the most efficient trade-off between technical
performance, voltage stability and sustainability. Optimal settings enable better
voltage balance, minimize system losses, and maintain an acceptable average voltage
level. In all cases, with proper adjustments, carbon dioxide emissions can be reduced.
Significantly compared to the base case. The results were validated through the best
objective function value, which is a reliable, holistic performance index, and
demonstrated the effectiveness of coordinated zoning optimization. This approach
thus provides valuable insights for future smart grid planning under ever-changing
operating conditions. There is renewable energy, and electric vehicles are widely used.
