【摘要】：提出了一种电动汽车分群调度策略,分别以电动汽车的出行结束时刻、所需充电时长、出行起始时刻和最大充电时延为判别量对电动汽车进行分群,并对每个子群的电动汽车分别制定延时充放电策略,以平抑配电网有功功率的日内波动并吸纳正午时段富余的光伏功率。该模型可基于统计模型为实际系统中的每辆电动汽车进行合理的调度指导,并充分考虑了电动汽车用户的满意度。此外,由于配电网中含有光伏、电动汽车等不确定因素,该模型采用区间数来描述电动汽车充放电功率等不确定量,并采用区间潮流对配电网进行优化。最后,通过算例验证了所提模型的有效性和采用区间优化的必要性。
[Abstract]:In this paper, a strategy of electric vehicle cluster scheduling is proposed, which is divided into three groups: the end of the trip, the required charging time, the travel start time and the maximum charge delay. The delay charge-discharge strategy is developed for each subgroup of electric vehicles. Based on the statistical model, this model can be used to control the intra-day fluctuation of the active power in distribution network and absorb the surplus photovoltaic power at noon. The model can be used as a reasonable dispatching guide for each electric vehicle in the actual system. In addition, because the distribution network contains photovoltaic, electric vehicle and other uncertain factors, the model uses interval number to describe the electric vehicle charge and discharge power uncertainty. Finally, the validity of the proposed model and the necessity of interval optimization are verified by an example.

【正文快照】： 0引言可再生能源的开发利用既缓解了能源危机,降低了污染物的排放,也提高了电力系统的经济性[1-3]。然而,由于风光发电系统本质上对气象条件的依赖,其间歇性和波动性会对电力系统的功率平衡、网络损耗等产生诸多负面影响。近年来,不断涌现的电动汽车为这一现状带来了转机[4]。
