Loss reduction and voltage improvement of Meshkinshahr distribution network with optimal capacitor placement using BPSO algorithm

This paper proposed a binary particle swarm optimization (BPSO) for optimal capacitor placement on Meshkinshahr distribution network. Harmonic distortion of voltage sources in network caused a double harmonic current injection, increasing network losses and incidence of resonance phenomenon. Therefore, the issue of expression, harmonic distortion of voltage sources is considered. Moreover, selected BPSO method to consider the discrete nature of the placement problem. Whereas, most of the articles have considered this problem continuously this issue caused reduction of the result accuracy to determine the size, exact location of capacitors and non-convergence of problem. Finally, the proposed method has been applied to Meshkinshahr distribution network to reduce loss and improve voltage profile with regard to harmonic distortion of voltage sources and annual load profile.
