Abstract
This paper presents a MATLAB GUI based software tool to solve the
optimal power flow (OPF) problem in power systems. The computer program,
called optimal power flow graphical user interface (opfgui), has been
developed to present the efficiency of different metaheuristic
optimization methods in solving the OPF problem. The opfgui program
offers a choice of seven standard IEEE test systems, six objective
functions, and ten optimization methods. The program generates not only
optimal solution, that is, optimum control variables and objective
function, but also important results such as, convergence profile, bus
voltages and bus powers, brunch power flows and losses, violating
constraints (if exist), and statistical evaluation of the results. The
software aims to support students in the course of power system analysis
that includes studies of the OPF. Using opfgui, the students can compare
the performances of different optimization methods in solving the OPF
problem.
