Keynote address:
Modular Multilevel Converters - A New Technology
Abstract:
The MMC technology, recently adopted by major manufacturers of HVDC equipment, has demonstrated clear advantages in comparison with two-level VSC in terms of losses, harmonics and footprint. Recently MMC technology has been applied by industry to large STATCOM and Drives. The benefits of MMC technology can be also used to improve the efficiency, power density and fault-tolerance of the existing solutions for connecting WT, PV or ES (for grid support or ultra-fast charging of EVs) to the distribution grid. Also, integrating the battery cells with a LV MMC has potential to improve battery cell balancing performance, life-time and increase the effective EV range. Cost and complexity are still the major challenges that need to be addressed. Different topologies and system architectures are analyzed and compared to the conventional.
Remus TEODORESCU received the Dipl. Ing. degree in Electrical Engineering from the Politehnica University of Bucharest, Bucharest, Romania, in 1989, and the Ph.D. degree in Power Electronics from the University of Galati, Romania, in 1994. In 1998, he joined the Power Electronics Section, Department of Energy Technology, Aalborg University, Aalborg, Denmark, where he is currently a Full Professor. Between 2013 and 2017, he has been a Visiting Professor with Chalmers University.
