Technico-economic analysis of EV Charging Station in Smart Grid

Abstract

The guidelines of the Green deal, the European plan to eliminate emissions by 2050, provide for a reduction of CO2 emissions by 55% by 2030, a stop to the sale of petrol and diesel vehicles from 2035, more car charging stations electricity in Europe (at least one every 60km) and the production of energy from renewable sources by 40% by 2030. Due to the climate neutrality that is desired to be reached by 2050 through the European Green Deal, the number of sold EV is constantly increasing along with renewable energy sources (RESs) share in local consumption. Due to the increase in EV sales, it is necessary to consider the installation of EV charging systems with a possibility to supply the EV load with RESs. however, the transition from a fossil fuel fleet to a predominantly electric one involves a whole series of problems that must find a solution. First of all the current inadequacy of the charging infrastructure. In all of Europe there are only 226,000 refueling points for electric cars and 7 out of 10 are located in Germany, France and the Netherlands. In this work the operation of a University Campus that has a smart grid composed of RESs and have the possibility to be a prosumer is analyzed along with the situation of using an EV charging system. The use of RESs along with EV and act as a prosumer contributes to the reduction of the pollutant emissions and thus contributes to reaching the target set by the European Green Deal Package.
