Abstract— This paper presents an efficient and reliable evolutionary based approach to solve the optimal power flow(OPF) problem. The proposed approach employs differential evolution algorithm for optimal settings of control variables. The proposed approach is examined and tested on the standard IEEE 30-bus test system with fuel cost minimization as objective. The proposed approach results are compared with the results reported in the literature. The results show the effectiveness and robustness of the proposed approach.
Keywords— Optimal power flow · Differential evolution algorithm · Fuel cost minimization
I. INTRODUCTION
In the past two decades, the problem of optimal power flow (OPF) has received much attention. It is of current interest of many utilities and it has been marked as one of the most operational needs. The OPF problem solution aims to optimize a selected objective function via optimal adjustment of the power system control variables, while at the same time satisfying various equality and inequality constraints.
Because the optimal power flow problem is
