Generation of Synthetic Distribution Grids for Sensitivity Studies on the Impact of E-Mobility

Abstract:
Due to climate policy targets, e-mobility is given high priority by decision makers. The effects on distribution grids are an integral part of many studies, and are often hampered by the lack of sufficient data availability. For this reason, this paper presents a method that generates realistic distribution grids on the basis of public data with focus on modelling private and public charging points based on today’s distribution of cars and parking spaces in Germany. The distribution of electric vehicles and charging points in the distribution power grids is based on a stochastic model. Therefore, a large number of simulations is performed to examine the convergence behaviour of the stochastic model. The exemplary results support the thesis that low electric vehicle penetration rates does not lead to significant violations of technical constraints in the distribution grids.
