摘要
水库中长期生态调度需要考虑天然入库径流的不确定性。首先描述径流的随机过程,接着以修正全年流量偏差(AAPFD)最小为目标函数,建立AAPFD最小且考虑发电量的水库中长期随机生态调度数学模型,并采用随机动态规划进行求解。实例计算表明,水库中长期生态随机调度模型与确定性调度模型相比,随机调度水位变化更平缓,更有利于保证水库生态流量,提高生态效益。
The mid-long term ecological dispatching of reservoirs needs to consider the uncertainty of natural inflow runoff.Firstly,the stochastic process of runoff is described.Then,the minimum Amended Annual Proportional Flow Deviation(AAPFD)is used as the objective function to establish the mathematical model of mid-long term stochastic ecological dispatching of reservoirs with minimum AAPFD and power generation is considered,and stochastic dynamic programming is used.The example calculation shows that the mid-long term ecological random scheduling model of the reservoir is more gradual than the deterministic scheduling model,and the water level change is more gradual,which is more conducive to ensuring the ecological flow of the reservoir and the ecological benefits is improved.
