Multiple DG allocation in radial distribution system using opposition based chaotic differential evolution technique

Abstract

Integration of Distributed Generators (DG) in radial distribution system is one of the important and challenging works in the power system. Optimal allocation of DGs in the network system leads to the minimization of the overall distribution power loss as well as the improvement of the voltage profile. The main objective of this work is to minimize the total active power loss by strategically selecting the optimal sizes of DGs and its optimal locations in the system. Operating power factor of different types of DG may be different, so the power factor is also considered for the case studies. To minimize the objective function, opposition based chaotic differential evolution (OCDE) technique is used in this work. The proposed technique is tested on IEEE-33 bus and IEEE-69 bus radial distribution systems to verify the effectiveness of the proposed method. The results obtained by this technique are also compared with other techniques. It is observed that the proposed technique performs well for this type of problem.
