The MathTech challenge is based on the tried-and-tested SEME (mathematics/enterprise study week) recipe proposed by AMIES, with the addition of debriefing sessions prepared in conjunction with the training organization iWips, which supports EDMH in the supervision of the entire MathTech cross-disciplinary training program.
Défi MathTech 2025
This edition of the MathTech challenge was designed and supervised by a group of EDF lab researchers. Upstream, they worked in depth to formalize ambitious and stimulating topics that were nevertheless accessible to exploration over the space of a week.
The proposed topic
Modeling and forecasting to optimize power system flexibilities.
The context
The context is the energy transition and climate change. The aim of the challenge will be to explore, during a week-long hackathon, the use of mathematical tools to improve the management of tomorrow's power system. More specifically, we'll be looking at forecasting issues (consumption, prices, renewables, weather/climate, demographics, economics), and optimizing diffuse flexibilities (e.g. electric vehicle charging).
The jury
The jury was made up of academic representatives from EDMH, the EDF lab expert researchers who proposed the above topic, and iWips trainers. In the unanimous opinion of the jury members, the presentations made by the doctoral student teams were of the highest quality.
