摘要
针对大规模电动汽车在城际间出行时的充电问题,提出了城际光储充电站的定容规划方法。首先,通过构筑城际高速路网充电引导系统架构,从而实现对电动汽车和光储充电站信息的实时有效耦合。其次,基于城际高速路网车流量的统计分布数据,结合电动汽车利用充电引导系统后的充电决策,兼顾用户和光储充电站双方利益,优化了光储充电站内充电机的数量。然后,根据各站光照条件、负荷水平,优化配置光储设备容量,并且结合分时电价,提出光储充电站内能量交换策略,以提高光伏消纳水平,从而进一步节省光储充电站的设备投资、运行维护成本。最后,在含有30个光储充电站的高速路网中对所提方法进行仿真验证。结果表明,所提出的定容规划方法显著降低了光储充电站的日均寿命周期成本,且有效兼顾了用户出行体验。
Aiming at the problem of capacity planning of electric vehicle light storage charging station in intercity highway network,a capacity planning method based on charging guidance is proposed.Firstly,an architecture of the intercity highway network charging guidance system is constructed to effectively couple electric vehicle information and light storage charging station information in real time.Secondly,based on the statistical distribution data of the traffic flow of the intercity highway network,combined with the charging decision of the electric vehicles using charging guidance system,taking into account the interests of both the user and the light storage charging station,the number of charging piles in the light storage charging station is optimized.Then,according to the lighting conditions and load levels of each station,the capacity of light storage equipment is optimized,and by combining time-sharing electricity price,the output time of the energy storage equipment in the station is adjusted,the photovoltaic power are efficiently accommodated,and the equipment investment of the light storage charging station is further saved.Finally,the proposed method is simulated and verified in a high speed road network with 30 light storage charging stations.Results show that the proposed method reduces the average daily life cost of the light storage charging station and effectively takes into account the user’s travel experience.
