基于年径流分类的水库优化调度函数研究Reservoir Optimal Operation Function Based on Annual Runoff Classification

Abstract: The traditional reservoir operation function is generally to maximize the long-term average power gen-eration, the guarantee rate and other indicators as the objective function. The connotation is that the av-erage expected benefit of the reservoir is maximized for long time series, but does not consider the vari-ation of annual runoff. It is obvious that the optimal operation function of the reservoir is related to the abundance of runoff that is quite different between the wet and dry years. In order to study the effect of annual runoff classification on reservoir operation function, a multi-objective operation model considering power generation and guarantee rate was established. The NSGA-II algorithm was used to optimize the operation function of Ankang reservoir. The results show that the runoff classification method is better than the long series optimization method. The largest non-inferior power generation solution can increase 0.71% power generation and 4.56% guarantee rate. The largest non-inferior guarantee rate solution can increase 1.37% power generation and 2.57% guarantee rate.
