Abstract
This contribution proposes a method to analyze the capabilities of low voltage grids to meet the demands of additional loads due to electric mobility. Probabilistic load models for both the domestic and electric vehicle loads are developed to give insight into the stochastic nature of load distribution and voltage bands. The results not only provide the maximum voltage deviations, but their probability of occurrence during a given period of time. With this information, a recommendation for future grid planning can be developed, which takes into account the increasing load caused by electric mobility. Furthermore, a load management system is proposed to reduce maximum load thus avoiding costs for increasing feeder capacities.
