A Survey of Optimal Power Flow Analysis of Longitudinal Power System

This paper presents a survey of publications on Optimal Power Flow (OPF) analysis of longitudinal power system with emphasis on the Nigerian power grid. It explained the nitty-gritty of OPF analysis. The study revealed that application of heuristic optimization techniques to OPF analysis have obviated the drawbacks of the previously used traditional optimization techniques with better solution quality, convergence time and flexibility. Although, the heuristics techniques were not flawless but well off to that of traditional techniques, a careful hybridization of both techniques seemed best off. This publication will be found handy for power system operators as well as researchers in an attempt to enhance the operations of the electrical power system.
