Optimal Location and Sizing of Coordinated Battery Swapping and Charging Station in Power and Road Transportation Networks

Battery swapping and charging station (BSCS) is a developing domain for energy storage and electrical vehicles (EVs). An electric vehicle charging station can be combined with a microgrid (MG) and a road traffic transportation network (RTTN) for cost-effective system operation to set up a new BSCS in a territory. This paper presents a new approach for the location and sizing of a BSCS constructed to solve the combined problem of high infrastructure cost, energy cost, and renewable energy support. The proposed model supports the participation between BSCS, MG, and RTTN for optimal location in the territory and power exchange between the MG and BSCS. This BSCS is connected with an electric network, photovoltaic (PV) units, wind turbines, and RTTN to offer auxiliary facilities and increased profit. The proposed optimization technique has been applied to a case study in Maharashtra, India, and it shows effectiveness by minimizing investment and operational cost along with location and sizing for the BSCS.
