The invention belongs to the technical field of elevators, and provides a peak clipping and valley filling elevator energy supply method and system based on day and night complementation and an elevator. A photovoltaic power generation system and an energy storage system are additionally arranged in an existing elevator system, and on the basis of power supply of a power grid in the daytime, the photovoltaic power generation system and the energy storage system are used for conducting auxiliary energy supply on the elevator; the multi-source energy supply of the power grid, the energy storage system and the photovoltaic power generation system is realized, and the power grid pressure is reduced; meanwhile, the energy storage system is used for conducting auxiliary energy supply on the elevator in the daytime, the photovoltaic power generation system is used for charging the energy storage system when energy supply does not need to be conducted on the elevator in the daytime, the power grid is used for charging the energy storage system at night, the rules that the electricity price cost at night is low and electricity consumption at night is in the valley are fully considered, and the purpose of peak clipping and valley filling is achieved. And the energy supply cost of the elevator is reduced.
本发明属于电梯技术领域,提供了一种基于昼夜互补的削峰填谷电梯供能方法、系统及电梯,通过在现有电梯系统中增加光伏发电系统和储能系统,日间在电网供电的基础上,使用光伏发电系统和储能系统对电梯进行辅助供能,实现了电网、储能系统和光伏发电系统的多源供能,降低了电网压力;同时,日间利用储能系统对电梯进行辅助供能,以及日间不需要对电梯进行供能时采用光伏发电系统对储能系统进行充电,夜间利用电网对储能系统进行充电,充分考虑了夜间电价成本低、夜间用电处于谷时的规律,实现了削峰填谷的目的,降低了电梯供能成本。
