Abstract

The analysis of the electrical behavior of microgrids including renewable sources, storage devices, nonlinear loads, and traditional components, has a high importance for researching and educating new professionals in energy systems. This paper presents the design and implementation of a flexible laboratory for testing modern electrical devices and emulating real microgrids. The laboratory design begins with the selection of several devices, followed by the structuring and implementation of a bus to connect the devices. The bus includes circuit breakers, contactors, copper bars, a ground connection, PLCs, and safety terminals. The flexible laboratory is experimentally validated by testing a single-phase converter, charging, and discharging three VRLA batteries, replicating a discharge profile and emulating a real microgrid installed on Isla Fuerte, Colombia. The results are used to evaluate the operation of the devices and to analyze the behavior of a real microgrid, demonstrating the usefulness of the laboratory in education and research contexts.
