Benjamin Stöckl is conducting a research stay at the National Technical University of Athens in Athens, Greece, from April to May 2026. During his stay, he is collaborating with Prof. Anthony Papavasiliou, an internationally recognized expert in electricity market design, energy system modelling, and optimization.
The research stay focuses on the further development and application of network reduction methods for large-scale European electricity system models. A central element of this work is the use of the Network Partitioning and Aggregation Package (NPAP). These methods make it possible to represent complex power grids in a simplified yet meaningful way. This allows models for renewable energy expansion planning to be solved more efficiently while preserving essential system relationships.
The work contributes to the question of how future European energy systems with high shares of renewable energy can be modelled and optimized. A particularly important aspect is the balance between model accuracy and computational effort, as detailed network representations in large-scale optimization models often require substantial data and computational resources.
The research stay strengthens IEE’s international collaboration in electricity system modelling and provides valuable input for ongoing research on the European energy transition.
