A Study On Optimal Reservoir Operation Model For The Cascade Dams 'Dahekou And Xishanwan' Located On Luan He River

Dahekou and Xishanwan two dams have located at Duolun County of Xilingaole Prefecture of Inner Mongolia. They have functions of electricity generating, irrigation, water supply and tourist. Optimal operating the dams has benefits for economic development of Xilingaoler Prefecture and ecology construction of Hunshandac desert land. The two cascade reservoirs have been considered as single dam in terms of their operating rules and optimal operating polices for it have been determined by discrete stochastic dynamic programming model.According to the variety of the genetic algorithm that produces stochastic variable and does not store a large number of discrete points, it renders an power generation and water supply optimal decision to a cascade dams system by using a multi-objective genetic algorithm which the appraising function in this method ranks the gene by comparing their performance in each objective function through the sorting matrix created by the objective function. The result shows that it can avoid of the COD problem.At last, in theory it summarizes the work and in practice gives the directions in the further research. The study is a sub-question of national nature science foundation major project "A Study of Water Resources Optimal Allocation for vegetation at Sand Source Area Between Beijing and Inner Mongolia." In the course of writing thesis, we gain aid financially from national nature science foundation.
