摘要
针对当前电动汽车的规模化发展趋势以及电动汽车到电网V2G(Vehicle-to-Grid)技术的应用,对电动汽车大规模接入后的配电系统可靠性进行相关研究。基于统计学建模方法,建立了不同控制模式下电动汽车的充放电功率模型以及时变负荷模型,提出了故障情况下采用V2G技术恢复供电的孤岛形成策略,计及元件的盆浴型寿命周期,利用序贯蒙特卡罗法对电动汽车接入后配电系统的可靠性进行全面准确的评估。以IEEE-RBTS Bus6测试系统主馈线F4为实例,从电动汽车负荷的控制类型、接入位置、渗透率三方面分别对系统的可靠性指标进行量化分析,研究结果为今后电动汽车的发展规划提供了有益的参考。
In view of the current large-scale development trend of electric vehicles and the application of V2G technol- ogy, this paper researches on the distribution network reliability considering large scale electric vehicles. The power demand models of electric vehicles with different control modes and the time-series load model are established based on statistical modeling method. The island formation strategy in fault cases using the V2G technology is proposed. Con- sidering the components life, the paper evaluates the reliability of distribution system with electric vehicle accurately using the Monte Carlo time sequential simulation. One main feeder of IEEE-RBTS Bus6 was calculated. Different scheme was quantitatively compared from different kinds of EVs, their locations, penetrations and then some conclu- sions could be made, which will be a reference to the planning of the electric vehicle charger in distribution system.
