Study on optimal regulation modelling of reservoir discharge

Abstract

The determination of optimal outflow discharge hydrograph in a pre-discharged period is an important component of the reservoir operation. Because of the high dimensional decision variables, lots of constrained conditions and complicated nonlinear relationships, it is usually difficult for the traditional methods and most of the current popular optimization software to handle the problem aforementioned. This research has presented the optimization models with single objective or multi-objective functions, and the optimization software package, 1stOpt, developed by the first author has been employed to solve the optimal problem. The research results have shown: 1) the optimal regulation models can meet various requirements with a universal feature, and thus may be applied in different reservoirs; 2) 1stOpt is a robust, easy-to-use and powerful optimization tool, and can be used widely in various engineering fields.
