Sonja Wogrin contributed her expertise in energy system modeling and time-series aggregation to the DTU PES Summer School 2026.

The DTU PES Summer School 2026 took place from 18 to 22 May 2026 at the Technical University of Denmark. The international summer school is a five-day intensive course on current research topics and methods in power systems, bringing together early-career researchers, academics, and industry experts.

This year’s program included lectures and discussions on topics such as power systems, electricity market design, renewable integration, machine learning applications in power systems, power system dynamics, cyber-physical resilience, energy system modeling, online learning in competitive settings, and prosumer market design. According to the organizers, around 70 participants from more than 25 countries took part, selected from over 150 applications.

Sonja Wogrin from TU Graz was invited as an international speaker and led a session on time-series aggregation for power system investment models. To make the methodological challenges more tangible, she turned the topic into an interactive challenge: participants who solved the task could win Austrian chocolates. In doing so, she demonstrated how complex questions in optimization and energy system modeling can be communicated in a rigorous, lively, and motivating way.  

Her contribution to the DTU PES Summer School highlights the international visibility of research at the Institute of Electricity Economics and Energy Innovation at Graz University of Technology and strengthens the exchange with leading research groups in energy systems, optimization, and electricity markets.
