EV Fast Charging Microgrid on Highways: A Hierarchical Analysis for Choosing the Installation Site

Abstract

This paper presents the development of a methodology to evaluate candidates places for installation an EV fast charging microgrid (EVFCM), composed by charging station, electrical grid connection, photovoltaic carport and a small wind generation. The methodology proposed focus on evaluating pre-defined points over eleven different criteria, such as: vehicle flux, proximity of medium voltage grid, availability of wind and solar generation, and socioeconomical data from place and population. The overall goal is to classify hierarchically this points to find the best options places to install the EVFCM. The case study is applied in the east of the state of Rio Grande do Sul, and the predefined points are sitting along important highways that connect Brazil to Uruguay.
