1. Analysis of the Impacts of the Electrification of the Vehicle Fleet in the Electric Power System in Curitiba
ABSTRACT The Market share of electrical vehicles has been rising in the past few years and tends to rise even more. According to the International Energy Agency, an increase of 50% in the number of electrical vehicles is expected. Whilst that increase is beneficial from a greenhouse gases emissions drop point of view, that rise could, on the other hand, repr
