为提高含混合式抽水蓄能电站的梯级水电站的保证出力和发电量,构建了年期望发电量最大的含混合式抽水蓄能电站长期随机优化调度模型,并运用逐次优化算法对模型进行求解。白山—丰满梯级水库优化调度计算表明,优化后白山水库保证出力抽水比不抽水增幅为24.94%,梯级电站总保证出力抽水比不抽水增幅为9.33%;白山水库年发电量抽水比不抽水增幅为4.86%,梯级电站总发电量抽水比不抽水增幅为8.64%。 In order to improve the guaranteed output and power generation of cascaded hydropower stations with hybrid pumped storage power stations, a long-term stochastic optimal operation model for hybrid pumped storage plants with expected maximum generation of power is constructed, and the model is solved by using successive optimization algorithm. The calculation of Baishan-Fengman cascade reservoir shows that the optimized pumping rate of Baishan Reservoir is 24.94%, and that of cascade hydropower station is 9.33% of that of non-pumping, and that of Baishan Reservoir is 4.86%. The total pumping capacity of cascade hydropower stations is 8.64% higher than that of non-pumping stations.
