We envision a system of systems to manage the increasing complexity of our energy systems.

In ZellNetz2050, the proof-of-concept for an energy system based on the cellular concept (or web-of-cells concept) is provided, including a complete system and market model oriented at solving the specific challenges of a 100% renewable energy system. For this purpose, one of the most extensive and detailed models for the German energy system in the year 2050 is created and used in a complex optimisation model as well as in a real-time operational model. A strong emphasis lies on an integrative approach, taking into account the existing infrastructure, and interoperability by standardisation of the interface to maintain compatibility to other approaches.
The primary scientific questions are
  • Is a cellular energy system efficient and economically feasible?
  • How does a celluar energy market has to be designed to address the specific challenges of the energy transition, especially the integration of many small flexibility providers?
  • Is a cellular energy system manageable during system operation?
  • What is the ideal compromise between transmission capacity and local flexibility utilisation?
Key Exploitable Results
  • Extensive and detailed energy system model for Germany
  • Cellular Energy Market Model
  • Organisational and structural model for an energy system comprised of energy cells
  • Methodoloy for a distributed and massively parallel solution of the optimisation problem
  • Automation and communication concept, Flexibility models
  • Demonstrations with real-world systems
