Model Establishment and Evaluation of Operation Function for Cascade Reservoirs

To meet the demand of actual optimized operation guidance for cascade reservoirs,the F-test and the goodness-of-fit test mechanism based on multiple linear regression algorithm are employed. Based on optimized operation result,cascading stepwise optimized dispatch function algorithm is proposed. The proposed algorithm is used to established the optimized dispatch functions for the Jinshajiang-Changjiang River cascade hydropower system. By selecting appropriate time,space and energy factors,the optimized dispatch functions are established with good operability and interpretability. Compared with traditional methods,the proposed algorithm has high simulate precision and practical value.
