A Coordinating Model Between Electric Vehicle Charging Station Planning Based on Thermal Maps of Vehicle Flow Rates and Distribution Devices Planning

摘要

Based on thermal maps of vehicle flow rates, this paper studies the optimizing method of charging stations’ capacity and location sets, to determining the classification information of the layout of the charging stations to be selected and the total charging capacity to be planned. Then, an optimal extended planning model of 10kV urban distribution network facilities was proposed based on the known classification information of the layout and total capacity of regional charging stations. Subsequently, considering that the above two models have a great impact on regional load imbalance, a coordinated planning model based on thermal maps of vehicle flow rates and distribution network facilities is proposed, which could be solved by double-level immune genetic algorithm. This model can solve the problem of regional load imbalance after the distribution devices and charging stations being connected at the same time. Finally, the effectiveness of the proposed model is verified by a coordinated planning analysis of practical charging stations and distribution network facilities.
