Methodology for the Development of a University Microgrid Laboratory in Virtual Reality Applied to Engineering Education
摘要
The COVID-19 pandemic has highlighted the need for new teaching technologies. The application of Virtual Reality (VR) in education has proven to be a great way of learning, making it more dynamic and motivating for the students. In line with the growing trend of converting real power plants into Virtual Reality (VR) simulators, this paper presents the current stage of development of a Virtual Reality Microgrid Laboratory (VRML). The physical microgrid (MG), made up of three single-phase solar photovoltaic systems of 2.6 kWp per phase, is installed in the Laboratory of Intelligent Electrical Networks (LabREI) at the Federal University of Ceará (UFC). The methodology for developing the VRML covers the following stages: collecting information of the real microgrid that is used as reference; selecting the modeling and development tools; specification of the MG objects given emphasis on technical and educational issues; modeling the MG’s objects using Blender 3D software; developing the MG VR environment in the Unity 3D graphics engine; developing, testing and validating the teaching methodology; and applying the VRML as a teaching tool in the electrical engineering courses. This article presents the methodology and progress in modeling the virtual components of the MG in the Blender 3D software, as well as the initial phase of development in the Unity 3D graphics engine.
