Model Experiment for the Temporal and Spatial High-Resolution Investigation of Future Load Balancing in Energy Systems

In FlexMex, energy system models are compared with each other in order to gain insights into how their resulting scenarios for electricity, heat, and mobility should be evaluated. A particular focus is on flexibility options, such as interregional power exchange, storage, or sector coupling.

For FlexMex, a two-part model experiment is carried out, in which scenarios for a future energy system with a high share of renewable energy is calculated using various models. The models use identical input data. Thus, different results can be attributed to different modeling methods and technology models. The following energy system models are compared in the project:

The RLI participates in the model comparison with an open energy system model developed using the open source modeling framework oemof.

FlexMex is part of the BMWi funding program "MODEX" for energy system analysis.

Project duration: January 2019 – December 2021

RLI assumes the following tasks within this project:

  • Calculation of the given scenario with oemof
  • Documentation of oemof's properties to identify differences and similarities with other models
  • Parameterization of the model based on data of the reference data set
  • Consolidation, documentation, evaluation, and interpretation of the results in close coordination with the partners
