摘　　要：围绕以往梯级蓄能调度图研究中存在的不足,在简述蓄能调度图原理、构成、绘制方法及模拟应用方法的基础上,针对调度线出力系数不确定性(条数和值)对蓄能调度图结果影响较大的问题,提出了一种调度线出力系数初始解构造方法和基于逐步优化算法的出力系数优化流程,能够快速准确的找出蓄能调度图的最优调度线出力系数,有效解决了传统方法在确定调度图出力系数时存在的人为因素影响大、精度低、效率差的技术问题。以雅砻江下游5库梯级为例进行实例研究,得到了最优调度线出力系数和对应的最优蓄能调度图,所得蓄能调度图模拟结果虽然相比于多维动态规划的确定性优化结果有一定的差距,但是其计算时间大大小于多维动态规划的计算时间,同时其水位过程更具规律性,实用性较强,对梯级水库群的实际调度运行具有重要的指导意义。Based on the brief introduction of the principle,composition,drawing method and simulation application method of cascade energy storage operation chart,an initial solution construction method of the output coefficients of operation curves and the optimization method of the output coefficients based on the progressive optimization algorithm are proposed.The proposed methods can quickly and accurately find out the optimal output coefficients of operation curves for the energy storage operation chart,and solve effectively the technical problems existing in the traditional method of determining the output coefficients of operation curves,such as the large influence of human factors,low accuracy and poor efficiency.Taking the downstream 5 reservoirs cascade system of Yalong River as an example,the optimal output coefficients of operation curves and the corresponding optimal energy storage operation chart are obtained.Although the simulation results of the energy storage operation chart are smaller than the deterministic optimization results of multi-dimensional dynamic programming,the calculation time is much shorter than that of multi-dimensional dynamic programming,and the water level process is more regular and practical,which is of great significance to guide the actual operation of cascade reservoirs.
