The invention discloses a scheduling method for a water-pumping and energy-storage unit. The scheduling method comprises the following steps of: I, detecting real-time water level of upper and lower reservoirs; and II, realizing regulation on a unit working condition according to real-time water level values, detected in step I, of the upper and lower reservoirs. The scheduling method for the water-pumping and energy-storage unit takes real-time water level conditions of the upper and lower reservoirs into consideration, compares acquired water level values of the upper and lower reservoirs with set different gear values of high and low water level, sets different scheduling strategies according to different compared results, can guarantee water level of the upper and lower reservoirs to be within reasonable level all the time, and realizes balance among peak-regulating frequency-regulating needs of an electric system, power plant safety, stable operation and a surrounding natural environment, so that a scheduling plan fits to a practical condition better, and is easy to implement.
