About the research project

This PhD project will develop appropriate dynamic models for offshore DC microgrids in order to analyse a wide range of technologies that enable transmission to clean and sustainable way of energy production. Components related to such technologies include photovoltaics, batteries, supercapacitors, electrolysers and fuel cells and are all natively DC. 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.
This project will review the challenges posed by DC microgrids in particular as to architecture and control aspects. These will include the commercial availability of suitable DC–DC converters (voltage, power, bi-directional capability, transient performance), how to set the DC bus voltage and strategies for energy management. The potential candidate will set up a viable DC microgrid architecture and explore the problems of transient behaviour with rapidly changing inputs and loads.
This project will be based in the School of Engineering with co-supervision of Griffith University. The student will have access to the physical DC microgrid lab and will be engaged in the work of designing a scaled-up (up to 1 MW level) containerized offshore microgrid in Tasmanian waters.
