摘　　要：以长江上游已建的36座水库为研究对象,考虑各种约束条件,从梯级局部和流域全局两个层次构建了以发电量最大为目标的优化调度模型,提出了针对流域优化模型的求解思路和方法-"混合优化算法"。研究结果表明:相比设计值,梯级及流域优化的电量、电力补偿效益均十分可观;流域优化的水电站群年均发电量及95%频率下的保证出力比设计值增加17.03 TW·h和2182.5 MW,比梯级优化值增加1.63 TW·h和348.4 MW;经联合优化调度后,三峡电站被补偿最为显著,发电能力进一步提高。Taking the 36 reservoirs which being in operation in upper reaches of the Yangtze River as study case, the optimal operation model which targets the maximum of power output is established for the cascade stations in sub-basin and all stations in upper reaches after considering various constraint conditions. The hybrid optimization algorithm is proposed for the solution of model. The optimization results show that： （a） comparing to design values, the power generation and output compensation benefit of cascade stations in each sub-basin and all stations in upper reaches are both considerable; （b） the annual average power generation and guaranteed output of 95% frequency of all stations in upper reaches increase 17.03 TWh and 2 182.5 MW to designed objectives respectively, and also are 1.63 TWh and 348.4 MW more than the optimization of cascade stations in sub- basin respectively; and （c） the Three Gorges Hydropower Station achieves the greatest compensation benefit and its generating capacity is improved after joint optimal operation.
