Reduction of real power loss by using Improved Bat Algorithm

In this paper, a newImproved version of BatAlgorithm (IBA) is proposed to solve optimal reactive power dispatch problem. The proposed algorithm utilizes chaotic behaviour to produce a candidate solution in behaviours analogous to acoustic monophony.    The proposed IBA has been tested on standard IEEE 30, IEEE 57 bus test systems and simulation results show clearly the better performance of the proposed algorithm in reducing the real power loss.
