Guest Lectures by Professor Torbjørn Thiringer and Dr. Igor Villareal

Time

16.04.2018 kl. 10.00 - 16.04.2018 kl. 12.00

Description

There will be two guest lectures on April 16, 2018 prior to the PhD defence of Ana-Irina Stroe

Title

The Return of the DC

Guest lecturer

Professor Torbjörn Thiringer, Chalmers Tekniska Högskola, Sweden

Time

10:00 - 11:00

abstract

DC was originally used when electrical systems was developed. In Göteborg, so much was built during 1884-1893, when Nikolai Tesla, showed the superiority of AC-supply, that it took until 1974, to remove all the DC-supply. However, today there are signs that DC might come back at least for the end supply of electricity. Already for higher voltages and long transmission distances, DC is often favorable in front of AC transmissions. In this presentation apart from some historical glimpses, the reasons for the possible return of DC for various power levels are presented.

About the lecturer

Torbjörn Thiringer works at Chalmers University of Technology, in Göteborg Sweden, as a professor in applied power electronics. He took his M.Sc and Ph.D at Chalmers University of technology in 1989 and 1996 respectively. His areas of interest include the modeling, control and grid integration of wind energy converters into power grids as well as power electronics and drives for other types of applications, such as electrified vehicles, buildings and industrial applications.

Title

Control and Management of the Batteries: Lifetime, SOH, SOC, Integration in the Application

Guest Lecturer

Dr. Igor Villareal, Centro de Investigaciones Technológicas, Spain

time

11:00 - 12:00

abstract

In this presentation, the objective is to present the main advances in the control of batteries, to maximize the profitability of storage systems in the final applications. Specifically, I will show the degradation models, SOC and SOH. Three of the main parameters for good control of the battery system.

About the lecturer

Dr. Igor Villarreal. Head of the Energy conversion and storage department, received his PhD in Electrochemistry applied to Lithium ion batteries (2001, Complutense University and CSIC, Madrid). He has been working at IK4-IKERLAN since 2001, when he was assigned to Lawrence Berkeley National Laboratory in USA until 2003, for Energy  technology transfer. Since 2010, he is Area Manager and has been involved in developing projects related to electrical storage systems for different industrial applications, such as trains, elevators, cranes, electrical buses, etc. He is an author of different papers and he has been the director of 3 PhD students and currently he is the director of three ongoing PhD students related to Lithium ion battery technology. He has been also a coordinator of the Batteries 2020 (FP7) European project.

 

The guest lectures will take place in pon 105, room 3.115, and all are welcome.
