One of the major developing trends of electric power systems, no matter in stand-alone form or in public grid form, is that more and more electronic power converters are adopted for the purpose of power conditioning or performance improving, for which a name electronic power system has been proposed. This will lead to quite a few technical challenges, one of them being the system small-signal stability issue, which is caused by the dynamic interactions among subsystems/converters and is quite different from the stability issue with conventional power grids. A review of existing analytical approaches to deal with this issue is presented, including traditional power system approach and some power electronics background approaches proposed recently. It turns out that the impedance-based approach is an appropriate analytical approach for such stability issue. An in-depth review of existing and recent work of impedance-based approach for DC systems is then delivered. Topics that will be covered include impedance-based stability criterion for 2 cascaded subsystems and corresponding load specification and stability monitoring methods, stability criteria for 2 parallel subsystems, stability criteria for multiple subsystems, and how to handle situations when interactions through communications also exist. Finally how these methods and techniques can be extended to 1-phase AC systems will be introduced in detail too.
Dushan Boroyevich received the Dipl.Ing. degree from the University of Belgrade, Belgrade, Serbia (formerly Yugoslavia), in 1976, the M.S. degree from the University of Novi Sad, Novi Sad, Serbia, in 1982, and the Ph.D. degree from Virginia Polytechnic Institute and State University (Virginia Tech), Blacksburg, VA, USA, in 1986.
From 1986 to 1990, he was an Assistant Professor with and the Director of the Power and Industrial Electronics Research Program, Institute for Power and Electronic Engineering, University of Novi Sad, where he later became the Acting Head of the institute. He then joined the Bradley Department of Electrical and Computer Engineering, Virginia Tech, as an Associate Professor. He is currently the American Electric Power Professor with the same department, where he is also the Co-director of the Center for Power Electronics Systems. His research interests include multiphase power conversion, electronic power distribution systems, power electronics systems modeling and control, and the integrated design of power converters.
Dr. Boroyevich was the President of the IEEE Power Electronics Society from 2011 to 2012. He is a member of the U.S. National Academy of Engineering. He was a recipient of the IEEE William E. Newell Power Electronics Technical Field Award and IEEE Power Electronics Society's Harry A. Owen Distinguished Service Award.
