Abstract
Power converters in the Megawatt range are becoming an integral part of the modern power system. Examples include HVDC transmission systems, renewable energy generation, large variable-speed drives, STATCOMs, rail grid interties and pumped hydro storage systems. These high power converters are operated at very low switching frequencies, require fast control loops and must often adhere to tight limits on their harmonic distortions. The typically used linear control methodology with pulse width modulation often impairs the achievable performance. This talk provides an industrial perspective on high power electronics, summarizes their challenges and proposes novel control techniques to address some of them.  Two pilot installations are discussed in detail including a 45 MW variable speed drive compressor system.

Tobias Geyer
ABB Medium-Voltage Drives

Tobias Geyer (M’08 - SM’10) received the Dipl.-Ing. and Ph.D. degrees in electrical engineering from ETH Zurich, Zurich, Switzerland, in 2000 and 2005, respectively, and the Habilitation degree in power electronics from ETH Zurich, Zurich, Switzerland, in 2017. After his Ph.D., he spent three years at GE Global Research, Munich, Germany, three years at the University of Auckland, Auckland, New Zealand, and eight years at ABB’s Corporate Research Centre, Baden-Dättwil, Switzerland. There, in 2016, he became a Senior Principal Scientist for power conversion control. He was appointed as an extraordinary Professor at Stellenbosch University, Stellenbosch, South Africa, from 2017 to 2020. In 2020, he joined ABB’s medium-voltage drives business as R&D platform manager of the ACS6000/6080.
He is the author of 35 patent families and the book “Model predictive control of high power converters and industrial drives” (Wiley, 2016). He teaches a regular course on model predictive control at ETH Zurich. His research interests include medium-voltage and low-voltage drives, utility-scale power converters, optimized pulse patterns and model predictive control. Dr. Geyer is the recipient of the 2017 First Place Prize Paper Award in the Transactions on Power Electronics, the 2014 Third Place Prize Paper Award in the Transactions on Industry Applications, and of two Prize Paper Awards at conferences. He is a former Associate Editor for the Transactions on Industry Applications (from 2011 until 2014) and the Transactions on Power Electronics (from 2013 until 2019). He was an international program committee vice chair of the IFAC conference on Nonlinear Model Predictive Control in Madison, WI, USA, in 2018. Dr. Geyer is a Distinguished Lecturer of the Power Electronics Society in the years 2020 and 2021.
