Description of the lecture

The energy transition in Germany and the global decarbonisation pose major challenges for the energy supply in all sectors (including heating, electricity and transport). Historically, the sectors have been considered independently of each other in planning and operation. For the future energy supply, concepts for multi-energy-systems are being discussed that are characterised by the intelligent coupling of sectors. These concepts enable a holistic view of all individual energy systems in order to define possible intersections and synergies that bring benefits to the entire energy system. In this context, potentials for energy generation, storage and conversion, as well as the flexibilization of supply and demand, play an essential role.

In the scope of the lecture, an overview of Multi-Energy-Systems is given in this reference. In the introduction to concepts, the history and the implementation of the energy transition, students gain a basic understanding of the goals and challenges associated with a desired transformation of the energy system. Based on an overview of the structure of today's energy system and its technological/energy components, as well as the underlying regulatory framework, the importance of cross-sectoral and flexible concepts in terms of multi-energy systems is highlighted and contextualised.

In conjunction with this, students learn how to apply basic methodological concepts for modelling of multi-energy systems. These include techniques for depicting and evaluating the energy supply structure, as well as methods of mathematical optimisation for planning and operating of energy systems.
