摘要
目前对居民区电动汽车(EV)充放电的调度缺乏对用户侧需求的研究,特别是难以兼顾EV用户的经济收益和出行需求。为此,在综合分析居民区日负荷特性以及EV用户需求的前提下,提出了一种考虑EV用户舒适度和充放电功率变化率的汽车与家庭互动(V2H)调度策略,基于遗传算法验证了所提调度策略的可行性和对居民区负荷及EV用户的优化效果。研究了不同的EV渗透率下V2H调度策略的适用性,结果表明EV渗透率的增加可以更好地改善居民区负荷的电网接入特性,且随着EV渗透率的增加,虽然EV用户的经济收益会略有下降,但均能保证EV用户的舒适度达到最大。
At present,there is a lack of research on the user-side demand for charging and discharging scheduling of EVs(Electric Vehicles) in residential areas. In particular,it is difficult to balance economic benefits and travel needs of EV users. Therefore,on the premise of comprehensive analysis of daily load characteristics of residential areas and EV users’ demands,a V2H(Vehicle-to-Home) scheduling strategy considering charging and discharging power change rate of electric vehicles and users’ comfort level is proposed,whose feasibility and optimization effect on residential load and EV users are verified based on genetic algorithm. The applicability of V2H scheduling strategy under different EV permeability is studied.The results show that the increase of EV permeability can better improve the grid-connected characteristics of residential load,and as the EV permeability increases,although the economic benefits of EV users will decrease slightly,the maximum comfort level of EV users can be guaranteed.
