The invention discloses an electric vehicle power grading adjustable multi-scene ordered charging method, which relates to the technical field of electric vehicle charging, and comprises the following steps: setting a charging power adjusting range of a charging pile, and applying a charging power grading adjustable strategy; determining a control scene according to whether a centralized control center exists or not, selecting centralized control if the centralized control center exists, and otherwise, selecting distributed control; an objective function is established, and the objective function aims to transfer the charging load of the electric vehicle from the peak period to the valley period, so that the peak load pressure is relieved; under the centralized control, a charging time period, maximum power charging or charging power grading adjustable strategy charging is selected according to the charging requirement, and under the distributed control, the charging duration is selected according to the delayed charging duration, and the charging power is selected according to the charging requirement; and orderly charging is carried out by adopting a charging power grading adjustable strategy, and the power of each charging pile is output. And the charging requirement of the electric vehicle is met, and meanwhile, good peak load shifting benefits are achieved.

    本发明公开了一种电动汽车功率分级可调多场景有序充电方法,涉及电动汽车充电技术领域,设定充电桩充电功率调节范围,运用充电功率分级可调策略;根据是否有集中式控制中心确定控制场景,有集中式控制中心则选择集中式控制,否则为分散式控制;确立目标函数,目标函数旨在将电动汽车充电负荷从高峰时段转移到低谷时段,从而缓解峰值负荷压力;集中式控制下,根据充电需求选择充电时间段、最大功率充电或充电功率分级可调策略充电,分散式控制下,根据延迟充电时长选择充电时长,根据充电需求选择充电功率;采用充电功率分级可调策略进行有序充电,输出各充电桩功率。满足电动汽车充电需求的同时,具有良好的削峰填谷效益。
