Abstract (EN): The adoption of electric vehicles (EVs) on a large scale can lead to significant social and economic benefits. The effort of promoting the use of EVs in road transportation is essential to meet the climate change targets and manage the ever unstable prices of perilously diminishing fossil fuels. On the other hand, there are still many uncertainties in the market regarding the acceptability of EVs by the final consumer. In this paper the effect of high penetration of EVs on thermal ageing of a real residential distribution transformer, part of an isolated electric grid, is analysed. A weekend scenario conditioned by off-peak tariff is studied. A transformer thermal model is used to estimate the hot-spot temperature (¿h) and top-oil temperature (¿o) given the load ratio in Sao Miguel, a Portuguese Island. Real data are utilised for the main inputs of the model, i.e. transformer parameters, residential load, peak and off-peak tariffs and EV parameters. Conclusions are finally drawn. © 2016 IEEE.
