Analysis of future electric mobility scenarios based on synthetic, georeferenced grid models

Abstract

The efforts to reduce the emission of greenhouse gases in the transport sector lead to an increase of electric vehicles and charging points. To assess the impact of electric vehicle charging on distribution grids, detailed models are required that take spatial and socioeconomic differences of regions into account. This publication presents a method for the bottom-up modelling of medium- and low-voltage grids based on georeferenced supply tasks. Further, a method to model future mobility scenarios for electric vehicles in a spatial resolution and the integration of these scenarios into the modelled grids is presented. The plausibility of the modelled grids is analysed by comparison to structural data of real grids. Finally, the results of yearly simulations for multiple scenarios for an exemplary grid area are presented to demonstrate the impact of the increase in electric vehicles and charging points on the electrical distribution grids.
