In order to reach the climate goals of the Paris Agreement, to which a large part of the world’s community is committed, it is necessary to achieve a high degree of decarbonization across the energy sectors. In Germany, the changes to the Federal Climate Protection Act in August 2021 reaffirmed these efforts, made them more concrete, and set higher goals. The strategy for achieving these goals is the installation of renewable energy sources, consisting mainly of wind turbines and solar power plants in the electrical energy system. Such intermittent renewable sources are highly dependent on the weather conditions, mainly solar radiation and wind speed. Therefore, they cannot be operated like conventional fossil power plants, but require high degrees of flexibility while balancing generation and consumption within the energy system. Furthermore, these flexibilities depend upon new operational strategies and concepts, digitization and cooperation of the sector coupled energy system, e.g., making full use of the flexibility within production and consumption, named “prosumption”, in the coupled heat, gas and electric grids. In other words, a cyber-physical system for the sector coupled energy system is required to generate and make use of these flexibilities. Information and Communication Technology (ICT) connects the physical technologies to the control, which is executed in line with the energy management strategies in future cyber physical energy systems.
