Abstract: A modified cuckoo Search technique is used for Capacitor Placement in Radial Distribution System with the Objectives of maximization of savings, minimization of voltage deviation and minimization of section current injection are used independently to find the Optimal Size of capacitors. The Power Loss Indices are used for location of Capacitor in System. A Novel procedure is used for location of capacitors by taking the Total Active Power loss minimum of the system as objective. To demonstrate the performance of the developed algorithm, a standard 15-node system is considered. The results obtained with the proposed method are better when compared with the existing method.

Keywords: Modified Cuckoo Search Algorithm, Optimal Capacitor Placement, Savings, Voltage deviation.
