Planning Methods of Electric Vehicle Charging Stations Scaling and Service Radius-Based on Grid Affordability and User Convenience

With the large-scale application of electric vehicles (EV), the reasonability of EV's charging facilities construction is extremely important to the convenient utilization of the charging facilities. In this case, this paper puts forward the planning methods of electric vehicle charging stations scaling and service radius based on grid affordability and user convenience. Premised on the distribution networks affordability, in the case of maximizing scale, this paper proposes the deciding methods of charging station service radius based on queuing theory model. Then guaranteeing the convenience of users as a prerequisite, ensuring the time-consuming of the entire charging process to be accepted by users, the service radius of the charging station is determined according to the queuing theory model. An example analysis is provided to verify the validity and accuracy of this method.
