Smart charging simulation and study for viability of implementation in DSO operating regions

Abstract

This paper demonstrated a Hardware-in-the-Loop (HIL) simulation carried out to study the implementation of smart charging strategies for electric vehicles (EVs). It aims to compare the impact of uncoordinated charging, time shifting strategy and dynamic power control for consumers in the years 2020, 2025 and 2030 with different demands and electrical connections. The methodology used to forecast the number of vehicles in the GOB06 feeder area was based on the number of consumers, number of total vehicles, and forecast of the expansion of EVs, in addition to different vehicles defined by the share of sales in 2020 at random times. The focus was on a medium voltage (MV) consumer with an 80 kVA charging electric bus, which happens to have high demand restriction and the need to make its use logistically feasible. One of the main results is the advantages of using time shifting in residential loads and dynamic control in commercial and industrial operations, avoiding the oversizing of equipment for electrical adaptations in the grid.
