Abstract

This thesis aims to introduce an approach based on the League Championship Algorithm (LCA) to determine the optimal number, placement, and size of Shunt Capacitors (SC) and PV-DG (Photovoltaic Distributed Generation) units in distribution systems. The primary goal is to minimize power losses while improving voltage profiles and enhancing the voltage stability index. The optimal locations of PV-DG and SC units are identified IV Distributed Control And Optimization in Electrical Smart Grids using the Loss Sensitivity Factor (LSF), while the LCA is applied to determine the optimal sizes of the DG units. The proposed method was validated using IEEE 33-bus and 69-bus radial distribution systems, with the results compared to other techniques from the literature. Simulations show that the LCA method is highly effective, delivering superior performance in determining the optimal location and sizing of PV-DG and SC units within the radial network
