Definition and Development of a structural model of a cellular energy system: in this work package, energy cells, energy cell levels and other central terms and their relations are defined leading to a well-defined image of the structure of an energy supply system following the cellular concept. Upon this, a migration concept is formulated illustrating a possible transition path from today's system to the target system.
Analysis and modelling of technology options: Here, all technologies considered in the optimisation model are determined and modelled. This includes all technologies for energy generation, transmission, consumption, and storage as well as for coupling energy sectors. Additionally, a continuous techno-economic evaluation of the technologies is conducted and societal acceptance investigated.
Aspects of energy economics: Within this work package lies the crucial innovation of ZellNetz2050 - the new, two-stage market design that puts system and market operation exclusively into the hand of a single entity, and utilises economic measures to prevent congestions while incentivising the economically efficient use of flexibilities.
Setting up the simulation models: This work package includes the development and regionalisation of the scenario framework, all aspects of the modelling of the energy grids as well as the implementation of all technology models both in the optimisation model and the operational model.
Automation and communication concepts: Here, the automations and communication connections necessary for the implementation of a cellular energy system are specified for the different energy cells levels.
Operational concept: The operation concepts defines system state and state variables on an abstract level. It serves as the basis for the operational simulations.
Offline simulation with the optimisation model: With the optimisation model the performance of the proposed cellular system design is investigated, evaluated and compared to other approaches with year-long simulations in hourly intervals.
Online simulation with the operational model: The real-time operational model enables the investigation of specific situations relevant for the secure operation of the energy system in a realistic control centre environment. This includes especially grid disturbances and elements of grid restoration.
Demonstration of the interfaces: In these work packages, the results of the previous works are applied to real systems together with the industry partners to identify challenges and develop solutions.
