一、概述随着计算技术的不断发展,各国许多学者对水电站水库群的联合调度问题进行了大量的研究。对于随机入流的长期调度研究,目前仍主要基于Bellman在五十年代提出的动态规划原理。而限于计算机的发展水平,当前仍难以克服多维状态变量情况下的“维数障碍”问题。而一般说来,特别是在较大流域,径流的时空相关关系往往比较密切,这使得在用动态规划方法求解时,不得不用更多的状态变量而遇到“维数障碍”问
I. Overview With the continuous development of computing technology, many scholars in various countries conducted a great deal of research on the joint dispatch problem of hydropower reservoirs. The long-term scheduling study of random inflows is still mainly based on the dynamic programming principles proposed by Bellman in the 1950s. But limited to the level of computer development, it is still difficult to overcome the problem of “dimensionality barrier” under the condition of multidimensional state variables. In general, the spatial and temporal correlations of runoff tend to be relatively close, especially in larger watersheds, which makes it necessary to encounter “dimensionality problems” with more state variables when solving dynamic programming methods
