A comparative approach of PSO and ABC algorithm for optimal positioning and capacity sizing of DG and Shunt Capacitor in a Distribution network using DLF algorithm

Placement and size optimization of Distributed Generation (DG) and shunt capacitors in a radial distribution networkhelps in minimizing system power loss and maintain appropriate system voltage .Of the numerous optimization methods available in the literature Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) algorithms are quite popular. An attempt has been made in this paper to compare the effectiveness of these two methods with the help of DLF algorithm to optimally place and size the DG and shunt capacitors in a radial distribution network. The required system data has been taken from the standard IEEE 69 bus radial distribution system. All computations were performed in MATLAB package.
