Sivanagaraju Journal on Electrical Engineering 2230 – 7176 4 4 14 18 Optimal Power Flow, Optimization Techniques, Modern Power Systems Operation, Cost Minimization A new approach to solve optimal power flow (OPF) problem in the power system is presented. In the proposed method, a two step initialization process have been adopted which eliminates the mutation operation and also it gives optimal solution with less number of generations which results in the reduction of the computation time. The feasibility of the proposed algorithm is demonstrated for a standard 2-machine, 5-bus system. The obtained results using proposed method are compared with the conventional optimization technique. The results reveal better solution and computational efficiency of the proposed algorithm. April - June 2011 Copyright © 2011 i-manager publications.
