Reservoir drought-resisting scheduling method and device

The invention discloses a reservoir drought-resisting scheduling method and device, and relates to the technical field of reservoir scheduling, and the method comprises the steps: dividing a current scheduling period into a plurality of time periods; according to the typical drought year incoming water-water demand data, the initial water storage capacity of the reservoir to be dispatched in each time period is determined; determining a drought alarm water level of the to-be-dispatched reservoir in each time period based on the initial water storage capacity of the plurality of time periods; based on the current historical meteorological data, determining a drought comprehensive index of the current time period; according to the drought comprehensive index of the current time period and the drought alarm water level of the current time period, the real-time effective available water amount of the current time period is determined; and determining a to-be-scheduled reservoir scheduling strategy of the current
