Efficient solving method for cascade reservoir combined power generation optimal scheduling model

The invention discloses an efficient solving method for a cascade reservoir combined power generation optimization scheduling model. The method comprises the steps that the storage capacity of cascade reservoirs at the beginning and the end of a scheduling period, the inflow of a faucet reservoir in the whole scheduling period, interval inflow between the reservoirs and various constraints of the cascade reservoirs are determined; discretizing the reservoir capacity value of each reservoir within the reservoir capacity upper limit and the reservoir capacity lower limit according to the discretization precision requirement; in the time period t, aiming at all possible reservoir capacity combinations of the cascade reservoirs at the beginning of the time period, searching a corresponding optimal reservoir capacity combination of the cascade reservoirs at the end of the time period, and storing the corresponding relationship as an optimal state transition relationship; enabling t to be equal to t-1, and repeatin
