水库群长期优化调度模型与水力关联矩阵

首先介绍了水库群长期优化调度模型,分析了该模型编制的程序在单库、梯级以及混联水库群中通用的制约因素.在水库群长期优化调度模型通用性设计方面,提出用水力关联矩阵来描述水库之间的空间位置关系和水力联系,并重点说明了水力关联矩阵的作用.然后,以DP算法与水力关联矩阵相融合为例,解决了将其设计为一般性算法过程中所遇到的问题,进而开发出具有一定通用性的水库群长期优化调度的算法代码.最后,将DP、DSPA和POA算法应用于雅砻江以及混联梯级长期优化调度中.

Modeling long-term optimal operation of hydropower plants using hydropower correlation matrix

Firstly, the model of longterm optimal operation of hydropower plants is introduced; and the restrictive factors on programming for single reservoir, cascade reservoirs and parallelserial reservoirs are analyzed. In order to reduce duplicate work in programming algorithm, the hydropower correlation matrix is proposed and its function is expounded emphatically, aiming at better describing the spatial location rela tionship and hydraulic connection of reservoirs. Secondly, by combining the dynamic programming (DP) and hydropower correlation matrix, the algorithm code of longterm cascade optimal operation for all-pur pose use is given, which overcomes the difficulties in converting the algorithm from special to general. Then the DP, dynamic programming with successive approximations (DSPA) and progressive optimality algorithm (POA) are applied to the longterm optimal operation of cascade hydropower plants at the Ya long River and the parallelserial cascade reservoirs.
