摘要
以居民乘用车行驶规律为前提,建立了基于排队理论(Queuing Theory)的电动汽车充电需求计算模型;在此模型基础上,通过分析充电设施与用户需求满足程度之间的关系,以及电动汽车充电对配电网的影响,提出一种居民小区电动汽车充电设施的优化配置方法,分为两步:充电设施数量的确定和充电设施最优连接位置的确定;充电设施数量是通过排队充电模型迭代计算得到;充电设施最优连接位置的是以充电对配电网电压影响最小为目标,以配电网潮流方程、充电功率平衡方程、电压、电流约束等为约束,建立优化模型计算得到。通过采用IEEE-33配电网和某居民小区的行驶规律数据分析计算,验证了所述方法的有效性。
This paper takes the resident passenger car driving rule as the premise to establish a calculation model of electric vehicle(EV)charging demand based on Queuing Theory.On the basis of the model,the paper analyzes the relationship between charging facilities and user demand satisfaction,and the impact of EV charging on distribution network,and also presents an optimal configuration method of EV charging facilities in residential areas,which method is divided into two steps:determine the number of charging facilities and select the optimal connection position of the charging facilities.The number of charging facilities is obtained by iterative calculation of QT charging model;the best connection location choice is calculated by establishing an optimization model,which aims to minimize the impact of charging on distribution network voltage,and set the power flow equation,charging power balance equation,voltage and current constraint as constraint.Finally the paper uses the data of IEEE-33 distribution power network and driving rules of a certain residential area to make an analysis and calculation,and verify the effectiveness of the proposed method.
