Planning of EV Charging Station with Renewable based Generation in an Overlaid Network Considering Uncertainty and Traffic Flow

The charging facilities should be available at appropriate locations to provide better services to the electric vehicle (EV) users. Also, optimally allocated charging stations are necessary in distribution network to maintain the power system healthy. In this work, a distribution network is taken to place charging station at optimal nodes and a road network is considered to simulate traffic flows. The distribution network is overlapped with the road network. Moreover, renewable based distributed generators (DGs) are allocated simultaneously. The main objective of this work is to reduce the energy loss of the distribution system. Two-stage model is used, where stage-1 is to allocate EV charging stations and DGs, and stage-2 is to allot EVs at appropriate charging station, based on the travel distances considering traffic flow. Arithmetic optimization algorithm for stage-1 and integer linear programming for stage-2 are used to solve the problems. The uncertainties are taken care by 2m point estimation method. Results show the energy loss reduction and voltage profile improvement due to optimal allocation of charging station in presence of DGs.
