Guest Lecture by Prof. Dr. Andrés Ramos Galán

Prof. Dr. Andrés Ramos Galán from Universidad Pontificia Comillas, Madrid, gave a guest lecture on "Efficient and Tight Model for Nuclear Power Plant Constraints in Flexible Operation".

On Friday, June 6th, 2025, the Institute of Electricity Economics and Energy Innovation (IEE) had the pleasure of welcoming Prof. Dr. Andrés Ramos Galán from Universidad Pontificia Comillas in Madrid, Spain, for a guest lecture.

In the IEE multifunctional room, Prof. Ramos Galán presented his current research on the topic:

“An Efficient and Tight Model for Nuclear Power Plant Constraints in Flexible Operation”.

The talk focused on how nuclear power plants – traditionally designed as inflexible baseload generators – can be better integrated into energy systems with high shares of renewable generation. As demonstrated by France, flexible operation of nuclear plants is not only possible but already a reality.

At the heart of the lecture were advanced modeling techniques for operational constraints such as xenon transients, as well as improved formulations for representing minimum stable operation times. Prof. Ramos Galán introduced a new, tighter formulation of these constraints that increases model accuracy while also reducing computational complexity. He showcased the advantages of these improvements through a case study using the RTS-GMLC test system.

We sincerely thank Prof. Ramos Galán for his insightful presentation and the engaging discussion that followed.
