Optimal Operation Model and Application of Reservoir Considering Dynamic Output Coefficient

The comprehensive output coefficient is an important dynamic parameter for the efficient operation of hydropower stations. In the existing studies, fixed values are often used, which is too ideal. A reservoir optimal operation model was established considering the economic operation and dynamic output coefficient of the plant, and the model was solved by genetic algorithm. The obtained reservoir optimal dispatch strategy shows that the benefit improvement of the optimal dispatch model using the dynamic output coefficient is better than that of the fixed output coefficient, and the maximum power generation benefit can be increased by 5.15%, which have reached the research goal of high-efficiency power generation and can provide references for the daily dispatch of reservoirs.
