The invention discloses a peak-valley time period calculation method based on a virtual energy storage technology. The method comprises: acquiring user information and historical load data by a powerconsumer intelligent electric meter; calculating the distribution weight of the annual power load of the power consumer in 24 time periods; calculating distribution weights of monthly power loads of the power consumers in 24 time periods; calculating the distribution weight of the weekly electrical load of the power consumer in 24 time periods; according to the distribution weights of the annual,monthly and weekly electrical loads of the power consumers in the 24 time periods, predicting peak, flat and valley electrical load distribution of the power consumers in the 24 time periods of the day; and taking the daily 24 peak valley flat power load prediction periods of the power consumer as power utilization parameters of a virtual energy storage control technology, and carrying out peak shifting control on the power utilization load. According to the invention, accurate prediction of the peak-valley period of the power consumer is realized, and the virtual energy storage control technology is utilized to effectively reduce the power consumption of the peak section of the power grid, improve the power consumption of the valley section of the power grid and maximize the peak clippingand valley filling efficiency of the power grid.
