**3. Methods**

The basis of the presented case study is a simplified cell-based grid model. Therefore, the methodology used for model development is explained below. This is followed by a description of the determination and grid-implementation of time-resolved load profiles, e.g., for households, as well as for the production profiles of already existent plants (hydroelectric power, biomass cogeneration and PV, as already mentioned in Section 2.1). We also explain the determination of the synthetic charging load profiles for e-mobility and the profiles of the PV potentials in this section. Furthermore, the necessary steps for the evaluation of the grid-side effects and the energy analyses are presented. Finally, we describe the scenarios we investigate during the case study.
