In order to coordinate and monitor the operation of multi-sector energy systems efficiently and flexibly, innovative, integrated concepts for control and instrumentation are required. In this context, the complexity of multi-energy systems requires new methodical operation and control approaches with reliable quality, robustness and cyber security properties. The development and demonstration of technologies for these challenges are the focus of the interdisciplinary facility COSYS-Lab (COntrol SYstems and Cyber Security Lab). The Chair of IT Security becomes funding for six positions for four years, including the establishment of a Young Investigator Research Group.
