A Review of the Optimal Allocation of Electric Vehicle Charging Stations

Abstract

With the growing concerns about the continuous increase in the concentration of CO2, in the atmosphere, resulting in global warming, there is an increasing trend towards a shift from internal combustion engine-based vehicles which rely solely on fossil fuels for their operation to electric vehicles. Wider adoption of Electric Vehicles (EVs) would not be possible without the installation of Electric Vehicle Charging Stations (EVCSs). The optimal placement of EVCSs is one of the concerns for large-scale deployment of EVs. If not placed optimally they can lead to range anxiety in drivers and cause stability problems at the grid. Researchers have used various optimization techniques for their optimal placement. Based on objective functions and optimization techniques this review work presents the optimal placement of charging stations (CS) to effectively solve the problem of their placement. This review work also presents various constraints which are to be followed while planning the CS location.
