针对金沙江下游梯级水电站在消落期的优化调度问题，结合实际调度需求，在分析水库水量平衡、水位、下泄流量及机组出力等多种约束条件的基础上，选取消落期内梯级水库群的发电量总和最大为优化目标，构建了金沙江下游梯级水电站的日尺度精细化调度模型，并采用DPSA-POA算法对模型进行优化求解，通过实际算例验证了模型及求解方法的有效性。研究结果表明，该调度模型能够在保证各梯级水库安全运行的前提下，充分利用水资源，最大化消落期的总发电量，为梯级水库群的精细化调度管理提供了理论基础和技术支持。

Aiming at the optimal dispatching problem of cascade hydropower stations in the lower reaches of the Jinshajiang River during the drawdown period, based on the analysis of the reservoir water balance, water level, discharge flow rate, and unit output, a daily-scale refined scheduling model was established by maximizing the total power generation of cascaded reservoirs and considering the actual scheduling requirements. The model was solved using the DPSA-POA algorithm. The effectiveness of the model and solution method was verified by the actual case. The results show that the proposed scheduling model can make full use of water resources and maximize the power generation in the drawdown period under the premise of ensuring the safe operation of each reservoir. Thus, it provides theoretical basis and technical support for the refined scheduling management of the cascaded reservoirs.
