Desarrollo de una plataforma para monitoreo y control de inversores Grid-Forming en Micro-Redes

Abstract

DOCUMENT IN THE PROCESS OF INTELLECTUAL PROPERTY. The increase in energy demand and the transition to renewable energy sources have created the need for solutions that optimize the stability of microgrids. This project aims to develop a real-time simulation platform to study DC-AC three-phase power converters with Grid-Forming control, using the Hardware-in-the-Loop (HIL) technique. The goal is to improve microgrid stability by incorporating renewable sources and providing educational tools for students and faculty at the Faculty of Electrical Engineering and Computing (FIEC-ESPOL). A real-time simulation model was created using RT-LAB and Simulink, implementing three control strategies (Droop Control, VSM, and Synchroconverter) to assess their performance. An HMI interface was also developed to monitor and control critical variables. The results showed that while Droop Control presents a sharp transient, the VSM and Synchroconverter strategies offer greater stability by providing virtual inertia to the system. The HMI interface facilitated real-time visualization and adjustment, improving microgrid management. It is concluded that real-time simulation with HIL optimizes the performance of microgrids with renewable energy sources and that VSM and Synchroconverter are more suitable for control applications in these systems.
