Pumping condition power adjusting method and device for pumped storage unit and medium

The invention relates to the technical field of pumped storage, in particular to a pumped storage unit pumping working condition power adjusting method and device and a medium. The method comprises the steps of determining unit generation power based on the relation between pumping power and to-be-absorbed power of a water pumping unit, calculating total efficiency when the pumped storage power station adopts a hydraulic short-circuit operation mode when the unit generation power and corresponding unit operation parameters meet preset requirements, and controlling the pumped storage power station to adopt a hydraulic short-circuit operation mode when the total efficiency meets the preset requirements. According to the method, the power of the power grid is adjusted by adopting the hydraulic short-circuit operation mode, and disturbance of intermittent clean energy grid connection to the power grid can be balanced more flexibly and quickly. The problem that the power of a constant-speed reversible unit cannot
