In this paper improved evolutionary algorithm (IEA) and enriched firefly algorithm (EFA) has been used to solve optimal reactive power problem. In the improved evolutionary algorithm by using the set of route vectors the search has been enhanced and in the enriched firefly algorithm differential evolution algorithm has been mingled to improve the solution. Both the proposed IEA&EFA has been tested in practical 191 (Indian) utility system and simulation results show clearly about the better performance of the proposed algorithm in reducing the real power loss with control variables within the limits.
