Prof. Grzegorz BENYSEK (Ekoenergetyka Polska S.A., Poland)

Title: New trends in green transport

Date: 26.04.2021, 10:15 CEST

Bio: Grzegorz Benysek His scientific research focuses mainly on issues related to the use of power electronic systems in the electric power system, the elimination of the negative impact of distributed energy sources on the grids and EVs charging infrastructure. Author of over 140 scientific papers and several books published by the SPRINGER London, translated into Chinese. Author and coordinator of over 20 research, development and implementation projects. As a result of research and development, many implementations have been created. He received a number of awards and distinctions, including: Innovation Personality, awarded by the Polish Chamber of Commerce. Member of the Management Board of Grupa Ekoenergetyka and member of the Supervisory Board of Ekoenergetyka Polska S.A.

Abstract: The main purpose of the speech is to present development trends both in the field of green transport and charging infrastructure. Green transport should be understood as road (passenger cars, buses, trucks), rail, sea and air electric transport. During the speech, the parameters of energy storage systems, parameters of electric vehicles and their requirements from the point of view of the charging infrastructure will be discussed. A hybrid model of charging infrastructure will also be discussed, including both garage/parking and fast/ultra-fast, i.e. charging HUBs. The next part of the speech will focus on issues related to the impact of the charging infrastructure on the power system in terms of power and energy demand. The last part of the speech will be devoted to 3D transport.

Dr. Piotr ZIMOCH (SMA, Poland)

Title: Renewable energy generation outlook and challenges

Date: 27.04.2021, 17:15 CEST

Bio: Piotr Zimoch received his M.Sc. and Ph.D. degrees in electrical engineering from the Silesian University of Technology, Gliwice, Poland, in 2016 and 2020, respectively. Since October 2020 he is working as a post-doctoral assistant at the Silesian University of Technology and as a power electronics development engineer at SMA Magnetics, part of the SMA Solar Technology AG group. His main research interests are quasi-resonant DC converters and application of wide bandgap semiconductor devices in power electronic converters.

Abstract: The presentation outlines perspectives and technical challenges for renewable energy market development. Since decarbonization is a driver for emission free energy generation systems over the entire lifecycle, robust and dispatchable renewable energy systems are of increasing demand. Strong market increase for energy generation and storage systems is forecasted. The emerging wide bandgap semiconductor technology allows for switching frequency increase; and thus is seen as a driver for size and cost reduction. However, increased switching frequency challenges performance of passive components. The first part of the presentation introduces a general market outlook for renewable energy generation systems, while the enablers are discussed in the following part, emphasizing the benefits of wide bandgap semiconductors contrasted with the demand for high performance passive components.

Prof. Anton RASSÕLKIN (Tallinn University of Technology, Estonia)

Title: Possibility of Digital Twins Technology for application in Propulsion Electric Drive

Date: 28.04.2021, 17:45 CEST

Bio: Anton Rassõlkin was born in Tallinn, Estonia, in 1985. He received the BSc, MSc, and Ph.D. degrees in electric drives and power electronics from Tallinn University of Technology (TalTech) in 2008, 2010, and 2014, respectively. In 2010 he received a Dipl.-Ing. degree in automatic from the University of Applied Science Giessen-Friedberg (Germany). He has been working in several companies as an electrical engineer and universities as a lecturer. Internationally he has been working as a visiting researcher at the Institute for Competence in Auto Mobility (IKAM, Barleben, Germany) and serves as a visiting professor at ITMO University (St. Petersburg, Russia) and Silesian University of Technology (Gliwice, Poland). Presently, he holds the professor's position in Mechatronics at the Department of Electrical Power Engineering and Mechatronics, School of Engineering, Tallinn University of Technology (Estonia). The main research interests are mechatronics and electrical drives, particularly for electric transportation, as well as autonomous vehicles.

Abstract: A modern trend for industry digitalization brings new demands for developing and applying the modeling and simulation approach. It is already not enough to have only a virtual representation of the object and run it independently from the physical object. The Digital Twin aspect indicates a connection between the physical object and the corresponding virtual twin established by generating real-time data using physical and virtual sensors. The electric vehicle is a complex system, which requires an accurate mathematical description for monitoring and validation. Nowadays, much attention is paid to the different parts of electric vehicles. The most examined quantities are the cost of capitalization, the power density of the drive (resulting from the system size and weight), and the reliability. Most of the existing electric drive testing techniques are mainly based on physical sensors, a Digital Twin of the electric vehicle propulsion system that represents physical object operation throughout its life cycle can recommend approaches to the drive regulator tuning, control looping, sensor allocation, and feedback arrangements.
