摘要
合理的峰谷时段划分是通过分时电价实现电动汽车有序充电的基础.为了研究不同时段划分下,电动汽车充电负荷分布改变后对负荷曲线的影响,根据驾驶习惯的统计数据构建了充电负荷对分时电价的响应模型.按照不同的时段划分设立了多个场景,运用蒙特卡洛模拟的方法从谷时段开始时刻负荷大小,系统最大负荷及出现时间,系统峰谷差等4方面得到了不同时段划分对配电系统负荷曲线的影响.算例结果表明,谷时段开始时刻越晚,充电负荷对负荷曲线的影响越小.
Reasonable peak and valley period partition serves as the basis of electric vehicles coordinated charging by time of use （ TOU） .To analyze the impact of electric vehicles charging load on load curve under differ -ent period partition , the charging load response model to TOU based on the statistics of the driving habits is built . Some scenarios are set according to different period partitions and the load of start time of valley period , numerical value and moment of peak load and peak-valley differences with the Monte Carlo simulation method are analyzed under those scenarios .The simulation results show that the closer start time of valley period to midnight , the less impact it has on load curve of distribution system .
