摘要
针对目前居民区配电装置额定容量不能满足大量电动汽车充电需求的问题,提出了一种考虑充放电接入退出随机性的电动汽车有序充放电控制策略。该策略以峰谷分时电价为背景,使电动汽车在负荷高峰时段向电网馈电、在负荷低谷时段充电以实现削峰填谷,并在充放电起始和结束时刻进行一定的随机性处理,使得负荷曲线更加平滑,避免总负荷瞬时突变。最后通过时序仿真验证了有序充放电控制策略的有效性。
Aiming at the problem that the rated capacity of power distribution devices in residential areas could not meet the charging requirements of a large number of electric vehicles,an orderly charging/discharging control strategy for electric vehicles that considers the randomness of charging/discharging access and withdrawal was proposed.Based on peak-valley time-of-use electricity price,the strategy enables electric vehicles to feed the grid during peak-load period and charge during valley-load period.In addition,it makes certain random processing at the beginning and end of charging/discharging periods to smooth the load curve and avoid the instantaneous change of the total load.Finally,the validity of the proposed charging/discharging control strategy was verified against the results of time series simulation.
