Distributed Artificial Intelligence The resilient and optimized operation of fully renewable and digitalized energy systems requires new paradigms in system operations. Intelligent multi-agent systems with self-x properties are therefore the focus of the work of the Distributed Artificial Intelligence (DAI) group.
The complete conversion of our energy supply to renewable energies is a central challenge of our time and an indispensable contribution to climate protection and energy autonomy. To achieve this, not only must the generation and consumption of energy be reconciled on the market, but energy systems must also be operated reliably and efficiently. With increasing digitalization, the historically evolved energy supply structures are becoming a complex and dynamic cyber-physical energy system in which thousands of components interact with each other. The digital systems must be able to adapt to different operating conditions and compensate for faults in operation as independently as possible, while meeting the requirements and needs of human users in a trustworthy manner.
Vision: self-organising, self-optimising and self-healing cyber-physical energy systems
The DAI group is therefore working on enhancing the distributed components of a cyber-physical energy system with intelligence and autonomy and networking them with each other based on concepts of the so-called Organic Computing. In research and development projects, we investigate the possibilities and limits of self-organising, self-optimising and self-healing cyber-physical energy systems.
Our main research topics
In the context of these characteristics of digitalized systems, collectively referred to as "self-x properties," we address the following key issues:
Resilient Self-X-Systems
Resilience is a system's ability to quickly restore stable system operation and become more robust to disruptions in the long term.
Learning in Self-X-Systems
The ability of agents to learn is a basic prerequisite for adapting system behaviour to new or changing conditions.
Transparency and Acceptance of Self-X-Systems
The acceptance of autonomously deciding, digitalized systems also depends on their ability to explain decisions in a transparent and comprehensible way. Find out more..
Modelling and Agent-based Management of Flexibility
Flexibility is the basis of almost all decision-making processes in digitized energy systems, especially when it comes to the use of decentralized energy plants in the distribution network. Find out more..
Open Science – freely available and open scientific results
As a research group, we are committed to transparent science - Open Science, which makes research results freely and openly available. The artefacts, data and publications we produce should be able to be used collectively and without hurdles in order to improve the quality of research and contribute to progress in society. An essential aspect of this is also the possibility of reproducing research results. Further information..
