Method for identifying and optimizing channel transit capacity of cascade reservoir area

Abstract

The invention discloses a method for identifying and optimizing channel transit capacity of the cascade reservoir area and relates to the reservoir operation scheduling and water conservancy information field. The method comprises steps that a vector Q composed of the discharge flow of reservoirs at all levels in the cascade reservoir area is randomly generated, and the vector Q is taken as a decision variable; constraints are defined, according to a navigation capacity determination table and a target function (1), the classical difference optimization method is utilized to compare with a historical value, whether the maximum iteration frequency is reached is determined, if not, a decision variable individual is selected for difference mutation, intersection and selection operations, andthe previous steps are repeated; if yes, the maximum channel navigation capacity and optimal water flow parameters of the cascade reservoir area corresponding to the optimal decision variable are obtain and outputted, and identification optimization are completed. The method is advantaged in that the navigation capacity of a navigation channel of the cascade reservoir area can be fully used, requirements of flood control safety and power generation of a power station can be further satisfied, and certain engineering practicality is realized.

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...
