Double-layer optimization scheduling method based on distributed photovoltaic flexibility and related equipment

The invention provides a distributed photovoltaic flexibility-based double-layer optimization scheduling method and related equipment. According to the method, through construction of an upper-layer economic model and a lower-layer scheduling model and alternate iteration of the upper-layer economic model and the lower-layer scheduling model, a distributed photovoltaic power distribution network optimization scheduling double-layer optimization model considering flexibility can be solved; the obtained optimal scheduling scheme of the power distribution network can ensure that the condition of insufficient flexible regulation and control capability does not occur in a photovoltaic output fluctuation range, so that the safe operation of the power distribution network is ensured, and meanwhile, the operation uncertainty of the power distribution network caused by the access of a large number of intermittent distributed photovoltaic power stations is avoided; and the operation flexibility of the power distributio
