Innovative Monitoring System Open Source Based: A Case Study of a Microgrid Lab with Digital Twin, PV and BESS Integration

As microgrids and modern low-voltage electrical systems continue to evolve, the demand for advanced monitoring tools has grown significantly. Ensuring reliable operation now requires systems capable of overseeing all functional aspects to maintain safety, stability, and a high degree of automation. To address these needs, SCADA (Supervisory Control and Data Acquisition) solutions have emerged, offering diverse structures and protocols, but ultimately converging on a common purpose: monitoring and managing power flows effectively. The Digital Twin, based on a BIM (Building Information Modeling) approach, is the best tool for managing microgrids because it is built during the 3D digital design process, following the entire life cycle of the system. The purpose of this document is to analyze the possibilities and limitations of the monitoring and supervision systems on the market, introducing our completely open-source alternative. Through the analysis of a case study within a university laboratory microgrid, different scenarios will be analyzed in order to evaluate the behavior of the system under the various conditions presented and propose solutions for future software updates.
