梯级水库短期优化调度的基本方法是首先采用动态规划方法按时间(以日为单位)规划三峡水库水位变化过程线,然后按日来进行优化调度,确定调度方案,建立一种以动态规划原理来解决梯级水库短期优化调度问题的数学模型。对于梯级水库短期优化调度,这种方法既考虑了面临时段的效益,又考虑了余留时期的效益,因此,据此制定的各时段的最优决策能够满足既定要求。
The basic method of short-term optimal operation of cascade reservoirs is to use the dynamic programming method to plan the water level change process of the Three Gorges Reservoir by time (in units of days), and then to optimize the schedule according to the day to determine the scheduling plan and establish a dynamic planning principle Mathematical model for solving short - term optimal operation of cascade reservoirs. For the short-term optimal scheduling of cascade reservoirs, this method not only considers the benefit of facing the period but also takes into account the benefit of the remaining period. Therefore, the optimal decision of each stage of the cascade reservoir can meet the established requirements.
