OPTIMAL PLACEMENT OF ELECTRIC-VEHICLE CHARGING STATIONS IN DISTRIBUTION SYSTEMS

Abstract

As the vehicles are becoming the basic need of the human been for the transportation, importance of fuel increased to very high level, and research started on different types of fuels. With the fossil fuels like oil, natural gas, petroleum, coal are excepted to last a little longer, not for longer duration, and the high awareness on the protecting our environment, creates very high importance of Electric Vehicles (EVs). But, the use of EVs are not much as the use of Petrol or Diesel vehicles. One of the reason for this is the mesh of the charging stations is very poor cross the globe. Inappropriate siting and sizing of EV charging stations, the city traffic mesh, and a degradation in voltage profiles at some nodes could have negative effects on the development of EVs. This paper discuss one of the solution for this issue. In this paper we first identify the optimal site of EV charging stations, for that two steps screening method is used in which first step considers environmental factors and second service radius of EV charging stations. Then, a mathematical model for the optimal sizing of EV charging stations is developed with the minimization of total cost associated with EV charging stations to be planned as the objective function and solved by a modified primal-dual interior point algorithm (MPDIPA). At the end, this paper have a plan for the demonstration of simulation results of the IEEE 123-node test feeder is proposed
