Summary: | The invention discloses a cascade reservoir day-ahead scheduling period end reservoir water level control method considering a water abandoning risk, and the method comprises the steps: obtaining an error distribution rule of runoff prediction and load prediction according to historical prediction/prediction data and actual data; according to an error distribution rule of runoff forecasting and load forecasting, calculating a time-period water abandoning risk of cascade reservoir hydropower station dispatching; according to a water abandoning risk calculation method, carrying out water abandoning early warning simulation on the historical scheduling process of the cascade reservoir hydropower station to obtain a water abandoning early warning empty report rate and a missing report rate of the cascade reservoir hydropower station; obtaining a critical abandoned water early warning value of each cascade reservoir hydropower station by taking the combined minimization of the abandoned water early warning empty r |
