In future low-voltage grids, the penetration of electric vehicles (EVs) will rise. Therefore, this contribution analyses how charging processes of EVs influence voltage stability and resource capacity utilisation in nine different low-voltage reference networks (rural, village, suburban – both typical networks and extreme value networks). The integration capacity of EVs with and without charging management is determined. As decentralized strategies, a reactive power control and a voltage-dependent active power reduction are chosen. Furthermore, it is examined, in how far the analysed charging strategies lead to a delayed charging end.
