本文应用系统分析的理论及方法,建立了一个多目标梯级水库群优化调度的动态规划模型。为避免在系统方程不可逆的情形下寻优时的内插,在模型中引入了“平衡变量”,从而使一个比较复杂的多维状态、多维决策问题,通过仅离散“关联变量”而建立起来的具有“优先权”结构的动态规划模型而变得相对容易起来,为解决此类问题提供了一种切实可行的方法。将该方法应用于湖北省随州市封江口水库群的优化调度,得到了满意的结果。
In this paper, the theory and method of system analysis are used to establish a dynamic programming model for optimal scheduling of multi-objective cascade reservoirs. In order to avoid the interpolation when the system equation is irreversible, the “equilibrium variable” is introduced in the model so that a complex multi-dimensional state and multi-dimensional decision problem can be established by only discrete “associated variables” With the “priority” structure of the dynamic programming model and become relatively easy to solve such problems provide a practical method. The method is applied to the optimal operation of the Fengjiangkou reservoir in Suizhou, Hubei Province, and satisfactory results are obtained.
