An application of Moth-Flame Optimization algorithm for solving optimal reactive power dispatch problem

This paper proposes an application of a recent nature inspired optimization technique namely Moth-Flame Optimization (MFO) algorithm in solving the Optimal Reactive Power Dispatch (ORPD) problem. In this paper, loss minimization is used as objective function of ORPD problem where the best combination of control variables such as voltage magnitude at generator buses, transformer-tap setting and injected MVAR will be obtained by MFO. To show the effectiveness of proposed algorithm, the IEEE 30 bus system is utilized and compared with other nature inspired algorithms. The results show that MFO perform better in obtaining less total system loss compared to those other selected algorithms.
