Central idea of C/sells
Central idea of C/sells

With C/sells, a cellularly structured energy system shall be developed, which is, visually spoken, oriented towards the sun's course from Bavaria in the east via Baden-Württemberg to Hesse in the north-west – the east-west solar arch. Energy supply, use, distribution, storage and further infrastructure services are optimised, in accordance with the subsidiarity principle, as autonomously as possible within the individual cells, e.g. real estate, quarters and cities. The connection of the cells into a network also allows common action for a secure and robust energy infrastructure. In doing so, an infrastructure information system will forward the exchange of energy at local and regional level. In order to justify the name of the project, technical solutions ("cells") will be developed on the one hand. On the other hand, citizens shall also be given new economic opportunities by participating in the energy transition ("sells"). Through the participation, the acceptance of the energy transition shall be further increased and an invitation to participate shall be expressed. Twelve core processes are defined as quasi DNA of the future energy system, by which roles and interactions of the traditional energy industry as well as of prosumers in the market and the network are organised. There are already 760,000 prosumers in southern Germany, who do not only consume but also produce electricity themselves. The diverse actor structure, which comprises all stages of the value chain of the cellular energy system, provides ideal conditions to develop and implement new cooperation models. A smooth transition from the demonstration up to the mass market is enabled by means of C/sells.

The FZI makes a significant contribution hereto, by designing intrinsic and extrinsic incentive structures for manufacturing companies and electric vehicle users and by evaluating them with a view on the potential of the mobilisation of the individual load flexibility.

The development of an intelligent and cross-cellular network of individual building energy management systems is the centre of attention of further research works. In order to enable the monetisation of flexibility, the FZI conceptualises intelligent, regionalised markets that shall prevent bottlenecks in the electricity supply system.

Besides conceptional works, procedures of the energy management and of the efficient market integration of commercial properties are developed and evaluated in real-life operation in the FZI House of Living Labs (HoLL). The FZI also supports the project partners in the cell "Wärmeflexibilität Mannheim" (heat flexibility Mannheim) by further developing algorithms for the use of flexibility options in heat networks.

Julian Huber leitet die Abteilung Information Management and Analytics am FZI Forschungszentrum Informatik. Zudem verantwortet dort innerhalb des Forschungsbereichs IPE die Aktivitäten rund um das Thema Smart Girds and Energy Markets. 2020 promovierte er am Karlsruher Institut für Technologie (KIT) summa cum laude zum Thema „Engineering User-Centric Smart Charging Systems“. Sein Anliegen ist es, Informationssysteme zu entwerfen, die dabei helfen können, Energie- und Mobilitätssysteme nachhaltiger zu gestalten. Seine Forschung konzentriert sich auf die Nutzbarmachung von Energiedaten (z.B. durch Prognosen) und die Nutzerintegration in nachhaltigen Informationssystemen.
