Abstract


Apart from all the potential benefits offered by Electric Vehicles (EVs), they demand some structural changes in the power network to fullfill their charging needs. In this paper, we have studied the impact of EVs charging load on the distribution transformer loading. Different penetration levels of EVs have been considered to see the effect of EVs charging load on the capacities of distribution transformers. A real case study has been considered for 14 different distribution transformers in the city of Vantaa in Finland to have the real impact of the study. Analysis about the peak power of each transformer with and without EV load for different power tariffs has been done. Possible upgradation need of the network based on various penetration levels of EVs is also analyzed.
