Abstract

Almost a third of global carbon emissions are attributed to the transportation sector – mostly resulting from a dependence on internal combustion engine cars. Electric Vehicles (EVs) have been thus identified as significant components of the carbon emissions reduction plan and, hence, developing a robust recharging infrastructure will increase electromobility's success. EVs may be recharged using slow, fast, rapid, and ultra-rapid technologies. However, rapid chargers consume significant energy from the grid within a short period of time, resulting in pulsating loads. An increased number of rapid chargers will alter the planning and management of all grid-connected operations. Using Deno runtime based on the JavaScript programming language, this paper presents an algorithm for creating stochastic charging profiles and estimating the demand of EVs from rapid and ultra-rapid devices. PSCAD/EMTDC is also used to examine the effect of chargers on the peak demand of a distribution feeder. The findings of this study increase confidence in the viability of connecting rapid chargers with battery energy storage units at strategic places of the distribution network.
