Abstract

Currently the requirements to be met by the lowvoltage grid are increasing. In addition to the growth of the distributed power supply the starting e-mobility is the main cause for this change. This paper contains the simulation of different low-voltage grids with a high number of connected electric vehicles. One of the results is that the utilization of the distribution transformer is the limiting criterion for a high number of electric vehicles in urban low-voltage grids. The comparison between a urban and a rural grid shows that the voltage drop is the limiting criterion in rural low-voltage grids. A solution to charge a high number of electric vehicles is a controlled charging system which makes it possible to charge all vehicles at night.
