LECTURE ABSTRACT

The contribution of renewable energy resources to the overall energy generation changes the power systems. With the increasing share of renewable based power generation, the electric grids transition from centralized to distributed generation, with a rapidly increasing number of power electronic components. Power electronics is a key enabling technology to transform and control electric energy with high efficiency. Wind and solar generators or battery storage systems need a converter as a power electronic interface to the grid. HVDC transmission systems in the Gigawatt range require power electronic converters to connect to the existing high voltage AC systems. All these generators and power electronic components have small time constants but flexible as well as fast control properties. In future “power electronics only” grids, the interaction of generators and stability in all operation points, in particular during faults, is expected to be a major issue. The lecture wants to give an overview on power electronic components in electric grids, presents grid converter control approaches and discusses converter models for stability investigations.

Personal Statement: 

Energy savings, renewable energies and the electrification of all energy sectors are the pathways to mitigate climate change. Power electronics is a key enabling technology, and I am happy to contribute with the research activities of our group and the education of students in two related fields: Wide Bandgap power semiconductors for efficient converter technologies, and research on the integration of renewables and converter control in power electronics dominated electric grids. Therefore, I look forward to give a lecture on “Clean Energy Transition toward Power Converter Dominated Power Systems” in the framework of the lecture series on Enabling Technologies for Clean Energy Transition.

Personal details:

I received the Diploma and the Dr.-Ing. degrees in Electrical Engineering (with honours) from RWTH Aachen University, Germany, in 1997 and 2004, respectively. In the course of the PhD work, I have been a Research Associate with the Institute for Power Electronics and Electrical Drives, RWTH Aachen, and Daimler-Chrysler Research and Technology, Berlin, Germany. In 2003, I joined Siemens AG, Krefeld, Germany, as Development Engineer, followed by positions as Senior Researcher at the Technical University of Berlin (TU Berlin) and as Professor at the BHT University of Applied Sciences Berlin. Since 2010, I have been Professor of Power Electronics with TU Berlin.

Key outputs, contributions, and achievements:

For more than 10 years now I have contributed to the advancements of GaN-based power electronics in a joint lab cooperation with the Ferdinand Braun Institute in Berlin. In consequence, I achieved to get a DFG priority program granted, where I am currently the coordinator. Within this program, in a joint effort 20 PIs from German universities and research institutes work on research projects on new GaN-based devices and converter technologies.

At the TU Berlin, I was involved in the study organization and the development of the curricula from the very beginning, and I was Dean of Studies from 2017 to 2021.

Concerning activities outside the university, I was a member of the Administrative Committee of the IEEE Power Electronics Society from 2017 to 2019, and I served as the Vice-Chairperson of the German ETG/VDE Steering Committee from 2013 to 2016. I am also active in the European Power Electronics and Drives Association (EPE), being a member of the International Scientific Committee and the Executive Council.
