Abstract

The invention discloses a method for identifying and optimizing the passing capacity of waterways in cascaded reservoir areas, and relates to the fields of reservoir operation scheduling and water conservancy information. The method includes: randomly generating the vector Q composed of the discharge flow of all levels of reservoirs in the cascade reservoir area, and using it as a decision variable; defining constraint conditions, and according to the navigation capacity discrimination table and the objective function (1) adopting the classic difference optimization method and historical Value comparison, to judge whether the maximum number of iterations is reached, if the maximum number of iterations is not reached, select the decision variable individual to perform differential mutation, crossover, and selection operations, and then repeat the above steps; if reached, obtain and give the optimal decision variable. The corresponding maximum passing capacity and optimal water flow parameters of the waterway in the cascade reservoir area are identified and optimized. The invention can give full play to the navigable capacity of the waterway in the cascade reservoir area, and can meet the requirements of flood control safety and power generation at the same time, and has certain engineering practicability.

Description

technical field [0001] The invention relates to the technical field of reservoir optimization dispatching, in particular to a method for identifying and optimizing the passage capacity of waterways in cascaded reservoir areas. Background technique [0002] With the large-scale development of water resources in my country's river basins and the improvement of comprehensive utilization requirements, shipping in reservoir areas has gradually received attention. Waterway regulation has always been the main method to improve the navigation conditions of the waterway, and its important supplement is hydraulic control measures. The formation of cascade reservoirs and the rapid development of dispatching technology provide a good opportunity for the hydraulic control of waterways in reservoir areas. At present, the research on optimal dispatching of cascade reservoir group shipping is mainly divided into two categories. One class takes the shipping water demand condition as a const...
