Distribution networks with Electric Vehicles

The technical challenges related to the market penetration of electric vehicles (EVs) in low voltage (LV) distribution networks are addressed. Steady state voltage profile of LV networks under different EV aggregation levels and penetration scenarios is investigated. A UK generic LV distribution network model and load demand figures from the electricity association were used to simulate EV impact on LV urban radial networks. Mainly, results show that the voltage profile is dependant on the aggregation level of EV and on the connection point. In particular, for 96 customers' equivalent aggregation of EV connection points, the voltage statutory limits are maintained. For low level of aggregation, equivalent to 24 customers, the voltage profile proves onerous.
