Embodiment Construction

[0093] Attached below figure 1 -5. A specific embodiment of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0094] Reservoir optimal dispatching is to seek the optimal water discharge scheme under the condition of known reservoir dispatching objectives and corresponding constraints. That is, according to the tasks undertaken by the reservoir, the dispatching target is extracted through analysis. Quantitative mathematical description of each target. On this basis, the reservoir dispatching model is constructed with the reservoir water level, time-period output, and water balance as model constraints. By using the multi-objective optimization algorithm to solve the model, the optimal water discharge scheme of the reservoir is obtained. The present invention mainly aims at the scientific problems that there is still room for further research in the optimiza...

Abstract

The invention relates to the technical field of reservoir scheduling, and discloses a reservoir ecological scheduling method based on coupling modeling optimization optimization. The method comprisesthe following steps: constructing a reservoir multi-target scheduling model; collecting reservoir characteristic parameters; correlation analysis of a plurality of scheduling targets; carrying out optimization solution on a double-target model by using an optimization algorithm; extracting scheduling targets of benefit conflicts according to a correlation result to form a target set; constructinga scheduling model, and constructing a reservoir optimization scheduling model according to the target set; solving the optimal scheduling model by using a multi-target optimization algorithm to obtain a Pareto scheduling scheme set; optimizing the scheduling scheme set according to a multi-attribute decision-making method to obtain a preferred scheduling scheme. According to the reservoir ecological dispatching method, the defects in a traditional modeling method are overcome, and then the most ideal dispatching scheme is obtained.

Description

technical field [0001] The invention relates to the technical field of reservoir dispatching, in particular to a coupling modeling-optimization-optimization reservoir ecological dispatching method. Background technique [0002] Reservoir optimization scheduling is a problem of reservoir utilization to maximize the economic benefits of water supply, power generation, irrigation, etc., and to optimize the process of releasing water from the reservoir. Reservoir ecological dispatching is a new dispatching mode that takes the ecological service functions of reservoirs and rivers into consideration on the basis of traditional reservoir dispatching. In the actual ecological regulation of reservoirs, there are: (1) the selection of scheduling targets lacks quantitative analysis, and the scientificity and basis of target selection are not sufficient; (2) multiple Pareto optimal solutions are obtained by model optimization, how to combine the actual optimal solution preferences. Th...
