摘要
建立了梯级水电站中长期联合优化调度模型,并采用逐步优化算法对其进行求解。以金沙江中游梯级水电站群为例,通过计算,得到了合理的联合优化调度方案。与各水库单独运行对比,其多年平均发电量、枯期发电量及水量利用率均有不同程度的提高。该结果表明此方法应用于实际生产中切实有效,也为梯级水电站联合优化调度运行提供了一种可行的途径。
A model of mid-long term optimal dispatching of cascade hydropower stations is established and a solution is given using progressive optimality algorithm.Taking the cascade hydropower stations of the middle Jinsha River as an example,a reasonable optimal dispatching solution is obtained through calculation.Compared with the situation that reservoirs are operated individually,the average annual energy output,energy output in dry season and utilization ratio of water are all improved to different extents by using united optimal operation.The result shows that this method is practically effective and offers a feasible option for the optimal operation of cascade hydropower stations.
