Biography
Kelvin Walenta studied Technical Physics at Graz University of Technology and graduated with distinction in February 2024. During his exchange semester at the University of Bergen, he focused on courses covering the simulation of physical processes and continued to specialize in numerical modeling during his master’s thesis. Since March 2024 he has been working as a university project assistant and PhD student at the Institute of Electricity Economics and Energy Innovation (IEE) at TU Graz. His research interests include energy systems, numerical modeling, and optimization methods.

Details
With the introduction of the new electricity economic system the uncertainty for investments is increasing. The risks for investing enterprises strongly increased and so new instruments for investment decisions are required. The goal of this project is to develop new methods and instruments for the determination of the optimal investment time.
