Braess' paradox in power grids
Constructing new lines in power grids may reduce the system's performance. We proposed an approach for the prediction of edges lowering system performance and define potential constraints for grid extensions.

Data-driven load profiles
In modern power grids, knowing the required electric power demand and its variations is necessary to balance demand and supply. We developed a data-driven approach to extract the trend and characterise demand fluctuations.

eXplainable AI for power grid stability
Numerous factors influence the stability of the power grid. We utilized the increasing amount of available data from energy systems to identify how certain generation types, load ramps etc. drive or stabilize the power grid frequency.
