The invention discloses a wind power and photoelectric absorption and cascade hydropower station combined dispatching method. The method comprises the following steps: predicting a wind power output process, a photoelectric output process and a reservoir inflow process; determining the scheduling flexibility level of the cascade power stations based on the reservoir inflow process prediction result, and selecting the power stations with the high scheduling flexibility level to perform cascade power station combined scheduling; constructing a scheduling optimization model based on a combined scheduling result of the cascade power stations; performing scheduling dynamic optimization processing on the wind power output process prediction result, the photoelectric output process prediction result and the reservoir inflow process prediction result based on the scheduling optimization model; carrying out comprehensive evaluation value calculation processing on a dynamic optimization processing result based on an en
