CONCLUSIONS
This paper presents the computer program opfgui for optimal power flow using metaheuristic optimization methods. The opfguihas been implemented in MATLAB. The purpose of this program is to use as a supporting tool during the practical lectures of the course of power system analysis.
The program is described on an example of the OPF solution for standard IEEE 30-bus test system. The program was run thirty times for each of ten optimization methods. This example show the main steps in solving the OPF problem, including selection of test system, display single-line diagram, edit system data, selection of objective function, selection of solution method, setting the algorithm parameters, program execution, and display of the results. Moreover, the students can compare the performances of different optimization methods based on statistical evaluation of the OPF results.
