The Optimization and Control (OC) group at the Institute for Automation and Applied Informatics (IAI) works on optimization and control methods tailored to applications in future energy systems. A strong focus is on interdisciplinary research between optimization, control, and forecasting. More specifically, we are focussing on three research fields. The first research field is the development of solution methods for optimal power flow. Here we consider uncertainty as well as distributed algorithms. Second, we aim to combine flat systems and hybrid automata theory to enable new control algorithms for the energy system. Finally, we examine the interplay between forecasting and optimization problems.
