7月5日“创源”大讲堂：Power Management and Load Transient Mitigation of Fuel Cell Systems
讲座题目：Power Management and Load Transient Mitigation of Fuel Cell Systems
Fuel cells are static energy conversion devices that convert the chemical energy of fuel (hydrogen) directly into electrical energy. They are clean and efficient power generation technologies, promising for static power generation such as distributed generation applications as well as transportation electrification such as fuel cell vehicles. For distributed generation applications, fuel cells have modular structures and can be placed near loads at different levels: houses, commercial buildings, or distribution centers. They can also be integrated with other renewable energy, such as wind or solar, to form a hybrid renewable energy system. For fuel cell vehicles, fuel cell stacks also normally work with battery and/or ultracapacitors to provide electric propulsion.
In this talk, the fundamentals and different types of fuel cells will be reviewed. After the introduction of power management of hybrid energy systems with fuel cells, the focus is given on load transient mitigation, which is important for both stationary and vehicle applications of fuel cells. Different load mitigation approaches and ripple reduction methods via DC/DC converters are discussed for fuel cell systems. DC/DC converters for fuel cell vehicles and a recent 180 kW DC/DC converter developed at Wayne State University will be introduced as an example for achieving high efficiency as well as low input current ripples.
Dr. Caisheng Wang received the BSEE and MSEE degrees from Chongqing University, China, in 1994 and 1997, respectively, and the Ph.D. degree from Montana State University (MSU), Bozeman, in 2006, all in electrical engineering. From 1997 to 2002, he worked as a research engineer and later the vice Chair of the Department of High Voltage Engineering at Zhejiang Electric Power Research Institute, Hangzhou, China. In August 2006, he joined Wayne State University (WSU), Detroit, MI, where he now is a Professor with the Electrical and Computer Engineering Department. Supported by NSF, DOE, Great Lake Protection Foundation (GLPF), WSU, and other sources with a total of over $12 million, he has been teaching and conducting research in the areas of renewable/alternative energy systems, power systems, power electronics, distributed generation, Microgrid and Smart Grid, and electric vehicles. He has authored/co-authored over 210 journal and conference papers with high citations, several book chapters, and two books.
He has served as an associate editor for several international journals, including IEEE Transactions on Smart Grid, IEEE Electrification Magazine, IEEE Power Engineering Letters, Electric Power Components and Systems, SAE Journal of Electronic & Electrical System for Passenger Cars, and served as a grant review panelist for NSF and the Department of Energy. He has won awards including Engineering Research Excellence Award, Excellence in Teaching of College of Engineering, Excellence in Teaching of the Division of Engineering Technology at WSU, IEEE PES EDPG Prize Paper Award, an MSU Foundation Graduation Achievement Nomination Award, and an Honorary Citizenship, City of Bozeman, MT, Award.
