Topic: Electric Spring Technology: A Green Technology for Smart Grid Applications to combat Climate Change
Prof. Ron Hui received his Ph.D degree at Imperial College London in 1987. Previously he held academic positions at the University of Nottingham, University of Sydney and University of Hong Kong. Presently, he is the MediaTek Endowed Professor at Nanyang Technological University and Chair Professor of Power Electronics at Imperial College London.
His research covers power electronics, wireless power, smart grid and lighting technology. He has over 120 patents adopted by industry and published over 320 refereed journal papers. His inventions underpin the key dimensions of the world’s first wireless charging standard “Qi” launched in 2010 by the Wireless Power Consortium. His recent works involve electric spring technology for smart grid applications. He is the recipient of the 2010 IET Crompton Medal and 2015 IEEE Technical Field Award (IEEE William Newell Power Electronics Award). He is a Fellow of the Royal Academy of Engineering, U.K., Australian Academy of Technology and Engineering, the US National Academy of Inventors and the IEEE. Currently, he was the Committee Chair of IEEE Medal in Power Engineering in 2020-2022.
Increasing use of wind and solar power of intermittent nature pose new challenges to power system stability, which requires an instantaneous balance of power supply and load demand. Traditional power systems adopt the centralized generation principle with the control paradigm of “power generation (supply) following load demand” and unidirectional power flow from the power stations to the load centers. With increasing capacities of distributed renewable energy generation, control paradigm for centralized power generation is no longer valid for the future power grid. Distributed renewable energy generation in the load centers implies bidirectional power flow in the power networks and renewable power generation has stochastic nature. Therefore, for an emerging power grid, there is a need for a radical change in control paradigm to “load demand following power generation” in order to achieve power balance for system stability.
This presentation addresses recent developments in Electric Spring (ES) technology that has been proposed as fast demand-response technology. Analogous to mechanical spring, electric spring can absorb fluctuations arising from renewable energy generation in order to stablize the voltage and frequency of the power systems. They can offer effective demand response with very fast response time in the order of tens of milliseconds (i.e. almost instantaneous for the power systems at mains frequency of 50Hz or 60Hz). Starting with a brief explanation of ES concept, this presentation describes various types of ES topologies and their variants reported since 2012 for smart grid applications. Recent research of linking large-scale electric vehicle charging infrastructure with electric spring functions will be described. Their implications on the power system level and future developments will be discussed.

In this talk I will present my research on creating artistic paintings called Escher tiling by optimization. Escher tiling is well known as a tiling that consists of one or a few recognizable figures, such as animals. Designing an artistic Escher-like tiling is a highly intellectual task because it is difficult to create meaningful tile shapes that satisfy the constraints to enable tiling. Our method creates Escher-like tiling automatically. For a given target shape, we optimize a tile shape that is as similar as possible to the target shape. Our method can generate satisfactory tile shapes even if the target shape is complex, such as a spider. Key ideas and optimization methods will be presented in the talk.
