Due to the increasing demand for electric vehicles and the required charging stations, the stress on the future distribution systems would increase. Proper location and capacity of these charge stations are critical factors that are to be determined based on detailed analysis of the distribution in order to avoid overloads, increased real power losses,excessive voltage drops, and damage to the infrastructure of the system. In this paper we propose a proper allocation methodology for charging stations in the distribution system in which network constraints and the operational standards are observed. This method develops a priority list of appropriate locations and the capacity of these stations based on allowable losses and voltage dropswhich are determined by the system operator. The proposed method is implemented in Matlab and is tested on two standard distribution systems including 33-bus and 136-bus networks. Numerical results presented and discussed to show the efficacy of the method.
