Since the 19th century, alternating current (AC) has dominated power generation, transmission, and distribution. However, the advantages of AC have progressively diminished in the context of designing effective systems for modern power grids. This has prompted extensive research into direct current (DC) microgrids, aiming to resolve the inherent limitations of AC and pave the way for an innovative, reliable, efficient, and cost-effective power system that represents the future.
In the digital age, the utilisation of DC has seen a significant upsurge, driven by the proliferation of information and communication technology and the deployment of advanced lighting systems, household appliances, instruments, and even industrial equipment. Notably, the latest developments in distributed generation and energy storage predominantly rely on DC technology, encompassing sources like solar photovoltaics, fuel cells, and rechargeable batteries. DC is experiencing rapid growth across various voltage levels, owing to its widespread application and the rapid advancements in power electronics, control engineering, and Internet of Things (IoT) technologies.
Our research focuses on the critical transition from AC to DC, positioning Australia and the University of Sydney at the forefront of pioneering technologies for future power systems.
