Abstract:

Driven by subsidies, the Volkswagen emission scandal, the discussion on driving bans for diesel cars and the decreasing prices for electric vehicles, it is expected that their numbers in Germany will increase dramatically in the coming years. Especially private charging infrastructure is often connected to low voltage networks. With charging power of up to 22kW per wallbox it could become a challenge especially for urban and suburban low voltage networks. This paper presents an approach to simulate the impact of charging infrastructure using a stochastic charging profile generator and time series load flow analysis. Exemplary simulations are carried out on real low voltage networks incorporating measurement data from these grids. The results show that charging infrastructure penetration can be integrated into the networks without causing reinforcement of the grid depending on the charging Power.
