Dynamics, stability and resilience of complex hybrid infrastructure networks

The dynamics, stability and resilience of complex hybrid infrastructure networks, with a particular focus on highly renewable power grids.
 

Infrastructure networks constitute one of the defining features of the Anthropocene. These continental scale systems exhibit all properties expected of complex systems that span dozens of spatio-temporal scales. The working group "Dynamics, stability and resilience of complex hybrid infrastructure networks", develops tools to study such systems from a complex systems perspective. The main focus is on power grids, where the ongoing energy transition introduces new dynamic actors and time scales, and poses complex coordination problems.

Due to the historic focus on power grids, the internal group name is COEN for COmplex Energy Networks.

Teaching

Student projects: Topics for Bachelor's or Master's Theses

Lecture: Complex Network Dynamics

Tools: In context of the "Long Night of the Sciences" we developed an interactive, browser-based simulation to demonstrate complex dynamic phenomena in power grids.

So far, the interface is not aimed at unexperienced users, i.e. undergraduate physics is necessary for understanding the model. Hence we suggest that "experts" assist the experiments and offer detailed explanations. We are currently working on a version that is accessible on the level of high-school physics and can be used in school for teaching purposes.

Research Transfer

A crucial part of our work is to ensure that our methodological and theoretical work gets used to solve real world problems. Alumni of our group have founded the start-up Elena International Gmbh that is building on open source tools coming out of academic research to provide grid developers and electricity providers with the know-how they need to build reliable grids with a high share of renewable energies. For more information see elena-international.com.


COEN's Software Projects

PowerDynamics.jl

Currently, we initiate an open source software project for the dynamical simulation of power grids in close cooperation with our partners at elena international

NetworkDynamics.jl

PowerDynamics.jl is based on the underlying package NetworkDynamics.jl, which provides the means to conveniently build heterogeneous networked dynamical system models.
