The use of computer simulations for educational purposes helps students assimilate more easily several theoretical concepts. As in other areas, for teaching and research in energy systems, it is available a wide range of simulation programs. Commercial programs are known to be computationally efficient, however, they are sealed, ie, do not allow modification in the source code or adding new algorithms. Because of this, many tools are developed in academics environmental, most with open source and typically designed for a specific aspect of the electrical system analysis. This is the case of UFUFlow program used to calculate the load flow, developed and used within the Faculty of Electrical Engineering, in Federal University of Uberlândia (FEELT/UFU). Therefore, this paper presents the main computer methods and programs available for the calculation and implementation of load flow algorithm which can assist students or researchers to choose the best tool that meet their needs. Additionaly, the improvements performed at UFUFlow, together with the tested and updated information provided here, can be used to encourage them to develop their own program.
