This work aims to minimizing the power loss in radial distribution system by placing optimally sized shunt capacitors at appropriate locations. The power flow solution of the proposed radial distribution network with different types of load models is obtained using Backward/forward sweep based load flow methodology. The sensitive nodes which are prone to voltage collapse are identified by the computation of voltage stability index for the installation of shunt capacitors. A nature inspired meta-heuristic search technique namely artificial bee colony algorithm which mimics the foraging behavior of the honey bee swarm is utilized to identify the optimal size of the shunt capacitors to be placed to achieve the loss minimization. The rigidness of the proposed optimization approach searching towards the optimal solution is tested on IEEE 69 bus radial test distribution system with different load models such as constant power, constant current, constant impedance, composite and exponential loads.
