Next-Gen Hydrogen Energy: The PrInCE Microgrid as a Scalable Solution

In the context of the global energy transition, new energy carriers are playing an increasingly important role in electrical systems. Microgrids offer a strategic solution for integrating intermittent renewable sources and various energy carriers, ensuring reliable and resilient energy distribution. However, implementing these systems presents technical challenges, especially in terms of reliability and integration of energy conversion technologies. This study examines the AC/DC hybrid microgrid developed at the PrInCE Laboratory of the Polytechnic University of Bari, which incorporates hydrogen as an energy carrier. The focus is on the solutions applied for dynamic voltage control on the DC bus, with particular attention to strategies aimed at preventing critical overvoltage and undervoltage conditions.
