Title 

Technical Challenges to More Electronic Power Systems and Distributed Generation

 

Abstract

Electric power systems have been experiencing many changes towards future, among which turning into more electronic, i.e. integrating more and more electronic power converters, and incorporating more and more distributed generations are the two major ones.  The technical challenges that the future power systems will be facing accordingly are then identified in detail.  The major issues caused by being more electronic and more distributed are discussed, with some possible state-of-the-art solutions also introduced.  The issues that are elaborated include the disputation about system inertia, the concern about lower transient over-rating tolerance, and new framework and specifications that need to be set up to ensure the user-friendly networking capability.  Future work that needs further research efforts are addressed too.

 

Biography

Jinjun Liu received the B.S. and Ph.D. degrees in electrical engineering from Xi'an Jiaotong University (XJTU), Xi'an, China, in 1992 and 1997, respectively.

He then joined the XJTU Electrical Engineering School as a faculty. From late 1999 to early 2002, he was with the Center for Power Electronics Systems, Virginia Polytechnic Institute and State University, Blacksburg, VA, USA, as a Visiting Scholar. In late 2002, he was promoted to a Full Professor and then the Head of the Power Electronics and Renewable Energy Center at XJTU, which now comprises 20 faculty members and over 100 graduate students and carries one of the leading power electronics programs in China.  He coauthored 3 books, published over 400 technical papers in peer-reviewed journals and conference proceedings, holds nearly 50 invention patents (China/US). His research interests include power quality control and utility applications of power electronics, micro-grids for sustainable energy and distributed generation, and more/all electronic power systems.

Dr. Liu received for eight times governmental awards at national level or provincial/ministerial level for scientific research/teaching achievements. He also received the 2006 Delta Scholar Award, the 2014 Chang Jiang Scholar Award, the 2014 Outstanding Sci-Tech Worker of the Nation Award, and the IEEE Transactions on Power Electronics 2016 Prize Paper Award. He is an IEEE Fellow, an Associate Editor for the IEEE TRANSACTIONS ON POWER ELECTRONICS, and from 2015, the Vice President for membership of IEEE PELS. He is on the Board of China Electrotechnical Society and was elected the Vice President of the CES Power Electronics Society in 2013. Since 2013, he has been a Vice President for China Power Supply Society (CPSS) and since 2016, the inaugural Editor-in-Chief of CPSS Transactions on Power Electronics and Applications. Since 2013, he has been serving as the Vice Chair of the Chinese National Steering Committee for College Electric Power Engineering Programs.
