Impact of charging electric vehicles in residential grid on the power losses and voltage plan

This paper offers a perspective of the development of Electric Vehicles (EVs), the actual state of the standardization, charging modes, impact of charging EVs in the low voltage networks and possibilities for implementation of Vehicle-to-Grid (V2G) concept. The main objective of this paper is to study the influence of charging a large number of Electric Vehicles on the power losses and voltage plan of the electric networks. The test were performed on a radial low voltage network with 12 consumers and there are studied three cases: without EVs, with a 50% penetration rate of the EVs and different time intervals for charging. Power flow calculation of the proposed network is realized in Neplan software for hourly values of power consume.
