摘要

在分析电动汽车充电行为的基础上，基于排队论建立了充电设施服务系统排队模型。在此基础上，研究了充电设施服务系统在排队等候中的概率特征，并定量分析了充电设施的运行效率。以充电设施服务系统总费用最小为目标函数建立了充电设施费用最优模型。结合电动汽车充电功率需求预测结果，研究了电动汽车充电设施不同配置方式对电网负荷率的影响。研究结果表明，通过合理配置充电设施，可以提高充电设备综合利用效率，从而进一步验证了所提模型的实用性和有效性。

Abstract

By analyzing the characteristics of electric vehiclescharging behavior，a queuing model for charging facilitiesservice system for electric vehicles based on queuing theory is established.On this basis，the waiting probability characteristics of charging facilitiesservice system for electric vehicles are studied，and the operation efficiency of charging facilities for electric vehicles is analyzed quantitatively.Furthermore，an optimal cost model for electric vehicle charging facilities is developed with the minimum of the total cost of service system as the objective function.By referring to the forecast results of electric vehiclespower demand，the influence of different charging facilitiesallocation schemes on load factors of power grid is analyzed.The analysis results show that the synthetic efficiency for charging facilities utilization can be improved by reasonable allocating charging facilities，and the practicality and effectiveness of the model are further verified.
