General Context
Key words: Hydrogen/electrolysis / MVAC/MVDC/converters
Hydrogen (H2) is globally recognized as an important component for decarbonizing energy systems. It also enables rapid and intermediate energy storage, especially as solar, wind, and storage systems become a significant part of the electrical grid. The current challenges limiting the growth of H2 installations are primarily cost and efficiency. It is crucial to propose innovative power supply architecture enabling cost reduction and higher efficiency of the H2 installation.
The medium-voltage AC (MVAC) architecture for H2 installations offers improved reliability and efficiency at a reduced cost. However, with the increasing use of renewable energy sources, the question of connecting renewable energies and H2 systems to a medium-voltage DC (MVDC) architecture arises. MVDC architecture has the potential to enhance efficiency, especially for future H2 installations with a strong presence of renewable energies. This internship will focus on studying MVDC power supplies and comparing them with MVAC power supplies.
