Large-Scale Reservoir Optimal Operation Under Uncertainty

Reservoir operation and water resources management is always one of hottest issues around the world. In order to study large-scale reservoir optimal operation under uncertainty, operation uncertainty of multi-objective reservoir was quantified in this paper. Then, the maximum of generated energy, the squared sums of water shortage and the quantified uncertainty were selected as the objective functions, and thus an integrated model for multi-objective reservoir operation is proposed. An experimental operation conducted with the Longyangxia Reservoir is employed for the demonstration of the proposed model. The results show that the calculated operation plan has a better performance than the actual reservoir operation process because the model can make the operation uncertainty lower and obtain the equilibrium solutions of power generation and water supply.
