Symposium TEPQEV: the presenters

Prof. Sjef Cobben

Sjef Cobben has worked in the electricity sector for forty years and was responsible for the safety of grids and connected installations. Currently he is working as part-time professor of Power Quality at Eindhoven University of Technology within the Electrical Energy Systems (EES) research group. Within this research group EES, Sjef is involved in the research on the quality of electricity supply, in which the energy transition (increase of solar and wind energy, heat pumps, electric cars) plays a major role.

In 2009 Sjef started his own company, CO-Education, spearheading the provision of training and advice in the field of electrical installations, electrical infrastructure, smart grids and smart installations and Power Quality.

Sjef has been a member of many national and international standards committees within NEC, CENELEC and IEC and is author of several books in the field of low voltage installations and Power Quality.

Tim Slangen

Tim Slangen obtained both his BSc (2017) and MSc (2019) degrees in Electrical Engineering from Eindhoven University of Technology. Currently, he is a PhD-candidate with the department of Electrical Energy Systems. His research is focused on the large-scale effects of electric vehicle charging on the power quality in the medium- and low-voltage grids. The increasing share of electric vehicles and fast-chargers can result in so-called “Supraharmonic” disturbances (between 2 and 150 kHz), which potentially influence the grid and all devices connected to it. Supraharmonics are not completely covered in standardization and their large-scale impact is still unknown. His goal is to obtain more insight on the large-scale impact of electric vehicles and fast-chargers on the power quality of the grid. His research is in cooperation with ElaadNL, the research- and innovation center for electric mobility, founded by the Dutch grid-operators.

Thijs van Wijk

In more than 10 years of employment at ElaadNL, Thijs has gained ample experience on testing of electric vehicles, charging stations and their influence on the electricity grid. He is operational manager of the ELaadNL testlab, which goal is to prevent charging issues in the field during regular and during smart charging. ElaadNL tests al new electric vehicles coming to the Dutch market on their interoperability with the Dutch charging infrastructure, their ability to smart charge, and their effect on and immunity to power quality changes in the electricity grid. At the moment Thijs is integrating DC charging, 15118 communication and V2G in the test process. Also, Thijs is active as an expert in several Power Quality related projects in which ElaadNL is involved. As background knowledge Thijs has a bachelor’s degree in electrical engineering (HAN, 2004) and a master’s degree in innovation sciences (TU/e, 2006).

Vladimir Cuk

Vladimir Cuk received the Dipl.Ing. degree in Electrical Engineering from the School of Electrical Engineering, University of Belgrade, Serbia, in 2005. From 2006 to 2009, he was with the Department of Electrical Measurements, Electrical Engineering Institute Nikola Tesla, Belgrade. In 2013 he received a Ph.D. degree from the Electrical Energy Systems Group, Eindhoven University of Technology, The Netherlands. He is currently an Assistant Professor with the Eindhoven University of Technology. His research interests include Electrical Power Quality and Power System Measurements and Modelling.

Erik de Jong

Erik de Jong is the Head of the Flex Power Grid Lab at KEMA Labs in Arnhem as well as part-time Associate Professor at the Electrical Energy Systems group at TU Eindhoven. Erik has been active in the field of power quality and grid compliance testing for over 16 years and is currently shaping the future of testing and validation methods for power electronic dominant grids from a testing laboratory perspective. Erik has been the KEMA Labs representative in the TEPQEV project since its inception and performed the testing campaign on the DC fast chargers together with TU Eindhoven in the Flex Power Grid Lab.

Thomas Gerrits

Dr. Ir. Thomas Gerrits is Power Conversion System Architect. He started the study Electrical Engineering at the Eindhoven University of Technology (TU/e) and received his M.Sc. degree in 2009. From 2009-2010 he worked as a lab assistant in the group of Electro mechanics and Power Electronics at the Electrical Faculty at the TU/e where he subsequently started as Ph.D. candidate. He received his Ph.D. in 2015. Currently he is working in the R&D department of Heliox as System Architect, focusing on high power energy conversion.

Ernst Wierenga

Ernst E.F. Wierenga received his M.Sc. degree in electrical engineering from the Eindhoven University of Technology, the Netherlands in 1996. In the same year he started at KEMA (DNV-GL) at the consulting department. In 2001 he joined TSO TenneT where he worked as a specialist protection for ten years. In 2020 he started at DSO Stedin as a strategist protection and power quality at the Asset Management Department. In this role he is involved in protection and power quality technology on high- and midvoltage grid. Besides that he started his own company KnowWatt; the main focus is teaching on the University of Applied Science (HAN Hogeschool).
