Abstract: Power systems are going through a paradigm change. Centralized large facilities are being replaced by millions of widely dispersed non-synchronous relatively small renewable or alternative power plants, plug-in EVs, and energy storage units etc. Moreover, the majority of loads are expected to contribute to system regulation as well. These bring unprecedented challenges to the operation of power systems. In this talk, it will be shown that the fundamental challenge behind this paradigm change is that future power systems will be power electronics-based, instead of electric machines-based, with millions of heterogeneous active players. Advanced control algorithms will then be presented to homogenize these heterogeneous players, followed by a distributed system architecture unified by the synchronization mechanism of synchronous machines. All power-electronics-enabled active players, large or small, supplying or consuming, will be controlled to behave like virtual synchronous machines so that they can all take part in the regulation of system frequency and voltage, in the same way as conventional power plants do. Moreover, the dedicated synchronization units, often phase-locked-loops, which are deemed to be a must-have component in grid-tied converters, will be removed. All the distributed active players only require local information and communicate with each other through the power network rather than through additional communication infrastructure, bringing stability, scalability, operability, reliability, security, autonomy and resiliency to next-generation smart grids.

Biosketch of the Speaker: Dr. Qing-Chang Zhong holds the Max McGraw Endowed Chair Professor in Energy and Power Engineering at Dept. of Electrical and Computer Engineering, Illinois Institute of Technology, Chicago, USA. He is well recognized worldwide as one of the very few leading experts in both control and power electronics, serving as a Distinguished Lecturer for the IEEE Control Systems Society and the IEEE Power Electronics Society. Before joining Illinois Institute of Technology, he was the Chair Professor in Control and Systems Engineering at The University of Sheffield, UK, where he built up a $5M+ research lab dedicated to the control of energy and power systems and attracted the support of Rolls-Royce, National Instruments, Texas Instruments, Siemens, ALSTOM, Turbo Power Systems, Chroma, Yokagawa, OPAL RT and other organizations. He obtained a PhD degree in 2000 from Shanghai Jiao-Tong University and another PhD degree in 2004 from Imperial College London (awarded the Best Doctoral Thesis Prize). He (co-) authored three research monographs, including Robust Control of Time-delay Systems (Springer, 2006) and a No. 7 Amazon Best Seller Control of Power Inverters in Renewable Energy and Smart Grid Integration (Wiley-IEEE Press, 2013). His fourth research monograph entitled Power Electronics-Enabled Autonomous Power Systems: Next Generation Smart Grids is scheduled for publication by Wiley-IEEE. He is an Associate Editor for seven leading journals in control and power engineering, including IEEE Trans. on Automatic Control, IEEE Trans. on Control Systems Technology, IEEE Trans. on Industrial Electronics and IEEE Trans. on Power Electronics.
