基于DPSA的水库优化调度方案研究

摘要

建立了水库发电优化调度模型，并采用动态规划逐次逼近法（DPSA）与动态规划（DP）嵌套模型进行求解。以西北某流域梯级水库为例进行计算，验证了模型的合理性，得到了合理的优化调度方案。通过对常规调度图模拟方案与优化方案的汛期弃水过程、汛初6月水位、凌汛期初11月水位和出力过程进行分析，总结水库调度运行特点，可为水库的实际运行提供参考。%This study established a reservoir generation optimization model and used Dynamic Programming Successive Approximation and Dynamic Programming nesting methods to solve it. Taking cascade reservoir in a basin in northwest China as an example,it validated the rationality of the model and got the reasonable optimization scheduling scheme. Through analyzing the abandoned water process in flood season,water level and power process in June (at the beginning of ice-jam flood season)and November (at the beginning of the melting ice flood season ) of the conventional scheduling simulation and optimization scheme, it summarized the reservoir scheduling operation characteristics,which could provide guidance for practical operation of the reservoir.
