Cascade reservoir dispatching model correction method based on double-layer step-by-step trial calculation

The invention discloses a cascade reservoir dispatching model correction method based on double-layer step-by-step trial calculation. The method comprises the following steps: judging the current scheduling period of an upstream reservoir; setting the upper and lower limits of the outbound flow of the upstream reservoir in the current period; calculating the capacity of the upstream reservoir in the next period; deducing the water level of the upstream reservoir in the next period; and calculating the capacity of the downstream reservoir in the next time period, deducing the water level of the downstream reservoir in the next time period, and repeating the steps until the initial solutions in all time periods are corrected. Compared with the prior art, the method provided by the invention has the beneficial effects that: for the non-aftereffect property of reservoir dispatching, only the reservoir outlet flow of the first time period is subjected to trial calculation from top to bottom by time period without
