摘要
与确定型优化调度将入流作为已知系列相比 ,随机动态规划将入流描述为随机变量 ,则更具合理性 ,因此该法是目前求解多库优化调度的最好方法 .由于入流的随机描述 ,极大地增加了计算量 ,从而经常导致“维数灾”问题 ,故而又限制了该法在实际中的应用 .本文以黄河上游 5个梯级水电站群为例 ,应用随机优化调度方法研究其兴利优化调度问题 ,通过合理的入流描述 ,有效地避免了“维数灾”问题 .
Considering inflows as random variables,the stochastic dynamic programming (SDP) is considered as the best method for solving the optimal scheduling problem for multiple reservoir system.But the so called “curse of dimensionality” and huge computational burden prohibit the use of this method in practice.Taking 5 reservoir system on the Yellow River as an example,this paper has studied the optimal scheduling problem by applying stochastic optimal scheduling method.Through the efficient describing inflows the “curse of dimensioality” problemis avoided.
