Abstract

One of the main short term challenges for the distribution networks will be the rapidly increasing penetration with EVs. In this paper, the effect of EV charging stations on the power quality of the distribution grid has been analysed. The preliminary analysis has been performed in accordance to the European Standard EN-50160 and to D-A-CH-CZ Technical Rules for the Assessment of Network Disturbances. The evaluation of the investigations has shown that in both cases no significant impact on the voltage quality occurs. Due to the strong grid connections in the investigated cases and the relatively low penetration of charging stations, no general statement can be made. In order to draw a generally valid conclusion, further investigations need to be made. The measuring campaigns have shown unbalanced load between the three phases. Even if the charging stations are properly all three phases installed this asymmetric load was determined.This investigation highlighted the importance of observing the development of electromobility in the districts of Zurich. In this way, areas with a high level of electric vehicle penetration can be detected and further measures (e.g. new measuring campaigns, load management, etc.) can be taken.
