Future Smart Grids Structures

Most renewable energy based power generation, energy storage systems and modern electronic loads are based on DC technologies. This necessitates new grid structure such as hybrid AC/DC and DC grids, which are key for future smart grids with higher efficiency, better power quality and enhanced capability to accommodate more renewable energy and modern loads. This project focuses on the development of hybrid AC/DC grids technologies, power electronics technologies, and power management technologies.
