Changing Power Transformer Metallurgy to Increase Responsibility of Electric Vehicle Fast Charge Profile

According to increase in number of electric vehicles and their charge stations, electrification overall condition has always been important in modern electric grids such as smart and micro grids. Transformer is one of the most effective parts of the electrification, but electric vehicle charge equipment generate uncertain, fast and short impulses in the demand side of the grid especially in transformers. Consequently, transformers have been shown unusual reactions which can change standard parameters such as temperature, hot-spot point or same parameters. Therefore, they need to change energy convention at the first step. Afterwards, electrification equipment should be designed by both technical and economic conditions. In this paper, transformers temperature reactions under the electric vehicle fast charge load will be analyzed with literatures. This research aims to determine the best way for cooling or preventing heat tension on the transformers, which sensors cannot sense. Uncertain temperature rise can engage most parts of the transformers such as cooling and magnitude systems.
