Difference to previous version: mastr_values_per_plz.csv now contains additional column "Solar_Capacity_Relative_Anteil" to allow for change in distribution of PV units in GridCreator. This dataset contains the necessary input files to create synthetic yet realistic low-voltage distribution grids for German grid areas using the open-source GridCreator Toolbox (INATECH-CIG/GridCreator: Automatically generate distribution networks based on open data). It contains grids: grid data for grid districts; Amme, J., Dubielzig, P., & Schachler, B. (2023). Distribution grid data generated by ding0 (v0.3.0-alpha) [Data set].
