Research

Decentralized, Passivity-Based Control of Networked Multi-Energy Systems

A sustainable energy supply requires to rethink energy systems. In order to achieve true climate neutrality, not only electrical power grids, but networked multi-energy systems consisting of electricity, district heating, gas, hydrogen, etc. grids have to be considered.

In my research, I develop decentralized control methods for components such as generators, consumers, and storage devices in different energy grids. For this, I exploit the unifying, generalizing property of physical-based methods (e.g. generalized equivalent circuits, port-Hamiltonian systems), the modularity of the system property of "passivity", and its relation to Lyapunov stability. The control methods developed in this way are modular and scalable, allowing to cope with the very high complexity of networked multi-energy systems.

In particular, the increasing number of components (generators, consumers, storage devices) that dynamically interact with each other at an ever-faster rate (i.e. on smaller time scales) due to the integration of renewable technologies can thus be managed. Components can be connected or disconnected without adapting the controllers of other components or jeopardizing stability ("plug-and-play").

If you are interested in a research collaboration (for PhD students), a bachelor’s or master’s thesis, a Hiwi job, or a research internship, please do not hesitate to contact me. Besides the open theses and offers, there is usually always something to do.
