【摘要】：基于排队论和成本效益分析法,提出一种电动汽车充储放电站储能系统容量配置方法。首先采用排队论构建电动汽车充电站充电服务系统排队模型,据此分析充电站n台充电桩同时提供充电服务的概率和预测充电站充电负荷趋势;其次,采用成本分析法建立充储放一体化充电站的建设成本、产生效益以及削峰负荷同直流充电机柜改造台数间的约束关系;综合二者,建立以成本回收年限为因变量,直流充电机柜改造台数为自变量的函数关系;最后,以某充电站为例,通过所提模型计算,演示了不同改造数量充电机柜的回收周期,验证了方法的可行性。
[Abstract]:Based on queuing theory and cost-benefit analysis method, a capacity configuration method for charging and discharging power station of electric vehicle is proposed. Firstly, the queuing model of charging service system for electric vehicle charging station is constructed by queue theory. Based on this, the probability of charging service provided by n charging piles in charging station is analyzed and the charging load trend of charging station is predicted. Secondly, the cost analysis method is used to establish the construction cost of the charging, storage and discharge integrated charging station, resulting in benefits and the constraint relationship between the peak cutting load and the number of DC charging cabinet retrofitting stations. Combining the two, the functional relationship is established, which takes the cost recovery years as the dependent variable and the number of the DC charging cabinet as the independent variable. Finally, taking a charging station as an example, through the calculation of the proposed model, the recovery period of different quantity of rechargeable cabinets is demonstrated, and the feasibility of the method is verified.

【正文快照】： 同电力系统常规负荷相比,电动汽车作为一种新型用电负荷,其有自身特征,例如随机性强,这势必会给电网安全稳定运行注入更多的不确定性[1],若大规模电动汽车随机接入电网可能会对电网产生不利影响[2-3]。例如,大量的电动汽车同时在电网原始负荷高峰时期进行充电,出现负荷“峰上
