A multi-objective optimal dispatching model combined with water quality objectives are developed for the non-flood season operation of the Three Gorges reservoir by introducing a dilution ratio and adopting a back-propagation neural network water quality forecast model. This dispatching model is solved using a genetic algorithm, a transformation of multi-objectives into single objectives and a technique of weighted convex fuzzy decision-making. The optimization results with the model provide optimal schemes that not only meet the demand for power generation scheduling but also improve the water quality of the tributaries, so that the overall efficiency of the reservoir';s non-flood season operation is optimal. Thus, this new model realizes the scheduling optimization strategy in effective multi-objectives coupling.
