Guest lecture on Design of Large-Scale LED Lighting Systems as Smart Loads for Future Power Grid
Abstract
The increasing use of intermittent renewable energy sources such as wind and solar power has raised new concerns about the stability issues of future power grid. Many renewable power sources are expected to be installed with and without central planning. The traditional central power control of power generation following load demand has to be abandoned. New control paradigm expects load demand to follow power generation in order to achieve power balance and stability. This seminar addresses a new smart load concept based on modern LED lighting. Using the General Photo-Electro-Thermal (PET) theory for LED systems, it will be demonstrated that large-scale LED lighting system can in fact be designed as smart loads that have their power consumption automatically following power generation. If properly designed, smart LED lighting systems are superior to other lighting in maintaining minimum luminous variation even if the power grid is weakly regulated.

Guest lecture on Wireless Power Transfer: Historical Development and Modern Applications
Abstract
Prof. Ron Hui will introduce the historical developments of wireless power transfer, from the apparatus of Tesla patented in 1900 to the launch of the world’s first wireless charging standard, Qi, in 2010. He will explain the basic principles laid down by Tesla - which are still valid today. Then he will zoom into the historic developments of the horizontal-flux and vertical-flux approaches for non-radiative "short-range wireless transfer". The charging methods adopted in the Qi standard are explained. The technical and safety concerns of the electronics industry are addressed. The major technical challenges (electrical, thermal, manufacturing, materials, EMC, safety etc] overcome in the process from a concept to a commercial product will be highlighted. He will share his views on future challenges and research trends for short-range wireless power transfer and the main issues involved in wireless EV charging. At the end of the talk, he will illustrate some new developments of “mid-range” wireless power transfer and their application potentials in power electronics, medical and superconductivity research.
The guest lecturer
Ron Hui received his Ph.D. at Imperial College London in 1987. He has held academic positions at the University of Nottingham, the University of Sydney and the City University of Hong Kong. He is now Chair Professor at both The University of Hong Kong and Imperial College London. He has published over 150 referred journal papers and has over 55 patents adopted by industry. He received two IEEE Power Electronics Transactions Prize Paper Awards for Wireless Charging Pad Systems in 2009 and General LED System Theory in 2010. His inventions underpin the key dimensions of the World’s 1st Wireless Power Standard “Qi” with free-positioning and localized charging features. He is a Fellow of the IEEE and IET. In 2010, he received the IEEE Rudolf Chope R&D Award, IET Crompton Medal and was elected to the Fellowship of the Australian Academy of Technological Sciences & Engineering.
