Abstract: The theory and modeling method for reservoir operation chart optimization using feasible range searching technique based on Genetic Algorithm is introduced from several aspects, including operation chart generalization, simulation model, objective function and optimization algorithm. In order to improve the search efficiency of feasible solutions in the optimization of operation chart, feasible range searching technique based on Genetic Algorithm is proposed in the model. Considering the geometric relevance among decision variables, the special encoding structure and information interaction mechanism of operation chart optimization is designed. Finally, the optimization model is structured based on NSGA-II algorithm. In the case of optimization operation in Siping Reservoir, the generated energy and energy reliability were all enhanced comparing with the simulated results of designed operation chart.

Key words: operating chart optimization, operating chart generalization, feasible range searching, genetic Algorithms
