Keynote for COMPEL 2021



Josep M. Guerrero, Director

Center for Research on Microgrids (CROM) at Aalborg University.

Microgrid Technologies: From the Land to the Sea and Out in Space 

This talk will begin by introducing the control of microgrids, the parallelisms with the human brain, and the research for possible sources of inspiration in the last frontiers of neuroscience.  In this keynote, microgrid technologies will be introduced to show how land-based microgrid knowledge can be introduced in shipboard systems. The talk will include power quality standards and issues in shipboard electrical systems, DC microgrids, and energy storage systems for ships and ferries, power management systems and optimization for vessels and offshore platforms, and power electronics enabling AC/DC grids in ships. Then, control in electric power systems of satellites and space platforms will be presented, showing approaches that are extended from terrestrial microgrids and explaining the differences and challenges when it comes to applying them out in space. Further, multi-microgrid systems will be discussed for moon craters in future lunar manmade bases. Finally, the extension from the hierarchical control of microgrids to bioastronautics in the control of closed ecological systems to support with oxygen, water, and food to the astronauts and thus creating new ecosystems for the moon and future mars bases.

Stability and Control of Inverter-Based Resources 

Power electronics has become a foundational technology for modernizing electric power grids. The massive integration of inverter-based resources is radically changing power system dynamics. The control dynamics of inverters tend to interact with each other and with the grid, leading to several stability problems. This talk will share a series of real-world stability challenges, and address the recent advances in analytical modeling and robust control techniques of inverter-based resources.  


Xiongfei Wang received a Ph.D. degree in energy technology from Aalborg University, Aalborg, Denmark, in 2013. From 2009 he has been with the Department of Energy Technology, Aalborg University, where he became an Assistant Professor in 2014, an Associate Professor in 2016, a Professor and Leader of Electronic Power Grid (eGrid) Research Group in 2018. He is also a part-time Full Professor at KTH Royal Institute of Technology, Stockholm, Sweden, from 2020. His current research interests include modeling and control of power electronic converters and systems, stability and power quality of power-electronics-dominated power systems, high-power converters.   

Dr. Wang serves as a Member-at-Large of Administrative Committee for the IEEE Power Electronics Society (PELS) in 2020-2022, a Co-Editor-in-Chief for the IEEE Transactions on Power Electronics Letters, and as an Associate Editor for the IEEE Journal of Emerging and Selected Topics in Power Electronics (JESTPE).

Jian Sun, Ph.D., Professor

Department of Electrical, Computer, and Systems Engineering, Director, New York State Center for Future Energy Systems Rensselaer Polytechnic Institute 

Impedance-Based Stability Criteria for Converter-Based Power Systems

An impedance-based stability criterion for grid-connected converters was published in 2011 to address emerging stability challenges associated with grid integration of renewable generation and high-voltage dc (HVDC) transmission. The method attracted broad interest when the predicted stability problems started to affect the industry from 2014-2015. Since then, impedance analysis has become a common practice in the industry to support new product design and system development. New impedance-based specifications and grid codes are also being developed.  As society moves towards decarbonized economies that rely 100% on renewables, the power grid will also evolve into a converter-based power system. Converter-related stability challenges that so far have been limited to the grid interface of individual converters are expected to become more systemic and will require more general modeling and analysis methods. This talk will review the new challenge and present the generalization of the impedance-based stability criterion to such converter-based power systems, including both ac and hybrid ac-dc grids. 

Dr. Jian Sun joined the faculty at Rensselaer Polytechnic Institute (RPI) in 2002, where he is currently a Professor in the Department of Electrical, Computer, and Systems Engineering. He is also Director of the Center for Future Energy Systems (CFES) funded by the New York State government. His research interests are in the general area of power electronics and energy conversion, with an emphasis on modeling, control, and different applications including renewable energy and power systems.  

Dr. Sun received his doctorate from the University of Paderborn, Germany. Prior to joining the faculty at RPI, he spent five years at Rockwell Collins working on power electronics for aircraft power systems and was a Post-Doc Fellow at Georgia Tech from 1996 to 1997. As Director of CFES, he is responsible for the strategic directions and development of the Center’s research, industry collaboration, education, and outreach programs. His professional activities in the power electronics community included serving as Editor-in-Chief of IEEE Power Electronics Letters from 2008 to 2014, Treasurer of IEEE Power Electronics Society from 2013 to 2020, and Vice President for Conferences since 2021. He works closely with industry in research and has also served as consultant/advisor to more than a dozen companies in the US, Europe, and Asia, including Rockwell, United Technologies, GE, Facebook, China State Grid, and TenneT.  

Dr. Sun received the IEEE PELS Modeling and Control Technical Achievements Award in 2013 and the R. David Middlebrook Outstanding Achievement Award in 2017. He is a Fellow of IEEE.
