Optimal placement of Capacitor Banks and Distributed Generation for Losses Reduction and Voltage THD Improvement in Distribution Networks Based on BBO Algorithm
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 7
Abstract
This paper presents a new approach based on Biogeography based optimization (BBO) algorithm for the simultaneous power quality improvement and optimal placement and sizing of capacitor banks and distributed generation (DGs) in the presence of voltage harmonic in radial distribution networks. The optimization aims at minimizing the power losses and voltage profils and THD improvement by DGs and capacitor banks placement for radial distribution system. Constraints include voltage limits and locations of installed DG and capacitors number/size, limit candidate buses. Biogeography based optimization is a novel evolutionary algorithm that is based on the mathematics of biogeography. In the BBO model, problem solutions are represented as islands, and the sharing of features between solutions is represented as immigration and emigration between the islands. A numerical application on a 33-bus bar network was performed. For effectiveness of the proposed procedure, the results obtained by BBO are compared with the genetic algorithm (GA).
