The research group on Electrical Energy Technologies and Systems focuses on frontier research to promote accelerated development of electrical engineering aspect of new and clean energy technologies and systems for a better environment. The group is the host of the Centre for Electrical Energy Systems and the International Research Centre for Electric Vehicles and links with the university-wide Initiative on Clean Energy and Environment. The research team has close collaboration with international and mainland researchers and organizations. Our research is generously supported by Research Grant Council of Hong Kong, CLP Power, Ministry of Science and Technology of China, Nature Science Foundation of China, China South Grid, Electric Power Research Institute of USA, and so on.  

Current research projects covers four main themes: energy systems, power electronics, electric transportation, and building service engineering. Research projects in energy systems include operation and control issues related to the integration of renewable energy resources into the power grid, real-time communication and control of smart grid, efficient operation of electricity market, and investment assessment (including risk assessment) of renewable generation. In power electronics, research focus is on enhancement of conversion efficiency, reduction of product size and improvement of reliability of power converters for renewable energy sources, electronic products (such as computers) and LED lighting. Active research in electric transportation is conducted in the areas of electric vehicles and electric railway systems. Recent research projects include electric propulsion, hybrid propulsion, green energy sources in electric vehicles, impacts of electric vehicles on environment, and vehicle-to-grid technology. Building services engineering covers building energy and management systems, smart meters, load signature identification, and smart homes.
