Project summary description:
Photovoltaics, batteries, supercapacitors, electrolysers and fuel cells are all natively DC. DC power is common in marine settings. Networking these components into a microgrid using high-efficiency DC–DC converters is logical, but problematic in practice, and few suitable DC–DC converters are available commercially.
Most microgrids are presently AC coupled with grid connection, therefore, involving multiple AC-DC conversions and issues of frequency synchronisation and voltage stabilisation. This project will examine the barriers to setting up pure-DC microgrids and create a bench-scale pure-DC hydrogen microgrid for experiments aiming to understand and resolve issues including transient response and control of the DC bus voltage.
