Optimal Power Flow Using an Improved Electromagnetism like Mechanism Method
Abstract In this article, an improved version of the electromagnetism like mechanism is developed and proposed to find the optimal solution for the optimal power flow problem in a power system. To show the effectiveness of the developed method, it has been demonstrated on standard IEEE 30 bus and IEEE 57 bus test systems for seven different objectives that reflect fuel cost minimization with generators that may have either convex or non convex fuel cost characteristics, voltage profile improvement, voltage stability enhancement, and active and reactive power transmission losses minimization. The results obtained using the improved version of the electromagnetism like mechanism method are compared with those obtained using different methods reported in the literature. Considering the quality of these results, the proposed method is a quite promising alternative approach for solving optimal power flow problems.
