Abstract

Efficient energy distribution and precise voltage regulation are essential for green hydrogen production using renewable sources; this research presents a hybrid DC microgrid model with a grid-forming control strategy tailored for green hydrogen production. The model integrates power electronics and renewable energy sources, with the Versatile Buck-Boost Converter playing a vital role in dynamic and static energy management, enabling scalable and efficient power regulation. The study also explores the integration of a photovoltaic system, a battery energy storage system, and a supercapacitor energy storage system, along with their respective modeling methods. Additionally, the model incorporates proton exchange membrane electrolyzers for green hydrogen production, demonstrating its capability to effectively integrate and manage diverse energy sources. This model yields valuable insights into the interactions between different components and control strategies within a DC microgrid, ensuring optimal performance and reliability. © 2024 IEEE.
