* This research is part of the ERC project "Scalable Control of interconnected Systems", with grant number 834142. * Modern society is critically dependent on large-scale networks for services such as energy supply, transportation and communications. The design and control of such networks is becoming increasingly complex, due to their growing size, heterogeneity and autonomy. A systematic theory and methodology for control of large-scale interconnected systems is therefore needed. In an ambitious effort towards this goal, this project is addressing the following key aspects: 1). Modeling by leveraging tools from learning and adaption; 2). Control design by utilizing structural properties of the system 3). Verification of system performance using decomposable certificates Energy networks (electricity and district heating) are used as a guiding examples for the development of theory and methodology. Collaboration with industrial partners will ensure that the research is relevant and useful in practice. When dealing with large scale networks arose in industry, computing the control policies and verifying the performance of the proposed algorithms require huge computational resources. These tasks are impossible to be implemented on personal computers. Therefore, it is inevitable to use supercomputing resources.
