Germany and Europe are to become climate-neutral. To achieve this, renewable energies must be further expanded and more closely interlinked with the building, transport and industry sectors. Coupling helps to integrate and use renewable energies. But it also changes how energy is converted, distributed and used. It is still an open question how a decarbonized, cost-efficient and reliable energy system is optimally designed.
Methodologically, such questions can be analyzed with modern energy system models. These models usually represent subsectors of the energy system, such as the grid infrastructure, the electricity market or the end-use sectors. Due to the complexity of the problem, other areas of the energy system are often only represented in a simplified way or neglected.
The Green VEgaS research project addresses the question of how the complex energy system can be analyzed and evaluated holistically. To this end, a tool chain is being developed for the multi-stage, iterative optimization and economic evaluation of the cross-sectoral energy infrastructure, generation and demand. The tool chain is based on existing models of the participating institutes, which will be further developed within the project against the background of sector and model coupling. Specifically, the energy system model DIMENSION of the EWI, the electricity grid model of the TU Dortmund and the heat and gas grid model of the GWI will be coupled.
EWI contributes its energy system model DIMENSION to the development of the tool chain for coupling the three models. Thus, it will be possible to consider transformation paths of the European electricity market and the end-use sectors across the board. The model will be further developed in the course of the project, especially with regard to sector coupling, and coupled with the models of the participating institutes:
