摘　　要：针对已有蓄能调度图研究很少关注大型混联水库群,且没有考虑多目标调度与蓄能调度图耦合的问题,通过对原有判别系数公式、水量平衡方程及蓄能计算公式的改进,将传统的纯梯级水库蓄能调度图模型进行拓展,提出了一种大型混联水库群蓄能调度图计算方法,并在综合考虑防洪、发电及生态等调度目标基础上,建立了大型混联水库群多目标蓄能调度图优化模型。以西江流域为例进行实例研究,得到了上游水库不同最小下泄流量情形下的多目标Pareto前沿,并基于此根据实际调度需求与约束提取了不同发电保证率要求及不同生态流量保证率要求下的最佳多目标调度方案。所建模型方法不仅可以很好地处理混联水库群蓄能调度图绘制与模拟中存在的复杂水量、水头联系,还可以有效地将所得多目标蓄能调度图应用到实际调度中。For the current research on energy storage operation charts(ESOC) of reservoir groups, little attention has been paid to large-scale mixed reservoirs, and the coupling of multi-objective operation with ESOC has not been considered. In view of this, by improving the original discriminant coefficient formula, water balance equation and energy storage calculation formula, this paper improves and expands the traditional ESOC model of pure cascade reservoirs, puts forward a new calculation method for the ESOC of large-scale mixed reservoirs, and establishes a multi-objective ESOC optimization model for mixed reservoirs based on a comprehensive consideration of flood control, power generation and ecological objectives. Taking Xijiang River Basin as an example, the multi-objective Pareto front of upstream reservoirs under different minimum discharges is obtained, and the optimal multi-objective schemes under different power generation guarantee rates and different ecological flow satisfaction rates are extracted according to the actual requirements and constraints. The model and method presented in this paper can not only deal well with the complex water volume and water head relations in the drawing and simulation of mixed reservoirs ESOC, but also effectively apply the obtained multi-objective ESOC to the actual operation.
