The application provides a gate linkage control method and device and a series water supply and power generation system. The method is applied to the series water supply and power generation system. The method comprises the following steps: obtaining water demand and current water level information of the series water supply and power generation system; wherein the current water level information at least comprises current river channel water level information and current water diversion main canal water level information; determining gate opening control decisions of a first water diversion gate and a second water diversion gate according to the water demand and the current water level information of the series water supply and power generation system; and performing linkage control on the first water diversion gate and the second water diversion gate according to the gate opening control decisions. The method provided by the above scheme can determine the gate opening control decisions according to the current water demand and the current water level information, so that the gate opening of the multiple water diversion gates can be controlled according to the gate opening control decisions, and the series water supply and power generation system can be accurately controlled.

The present application relates to a kind of canal water level probability prediction method and system based on MC Dropout and CNN-LSTM, belong to water level prediction technical field.The prediction method includes the following steps:s101.data acquisition;S102.model architecture building;S103.model training and inference.The present application fuses convolutional neural network (CNN) to extract the local space-time characteristics of multi-source hydro-meteorological data, long short-term memory network (LSTM) captures long time series dependency relationship, and integrates Monte Carlo Dropout (MC Dropout) variation inference mechanism and heteroscedastic loss function, realizes the accurate prediction of key water level observation station, uncertainty decomposition (Aleatoric uncertainty and Epistemic uncertainty) and the synchronous output of confidence interval.
