Analysis of optimal power flow problem based on two stage initialization algorithm

This paper focuses on providing a new and comprehensive optimization algorithm to solve constrained Optimal Power Flow (OPF) problem in the power system. Unlike the OPF solution algorithms existing in the literature, in the proposed algorithm, a two stage initialization process is adopted and the mutation operation is not used. 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 Himmelblau function and IEEE 14 bus system. The obtained results using proposed method are compared with the existing optimization techniques. The results reveal better solution and computational efficiency of the proposed algorithm.
