Embodiment Construction

[0062] In order to solve the problems existing in the prior art, the applicant has carried out in-depth search and research. The applicant found that most of the existing research is method-oriented, and its research focuses on the establishment of a comprehensive optimization model for reservoir flood control and dispatching schemes in terms of the determination of index weights and the selection or improvement of multi-objective decision-making methods.

[0063] In fact, compared with the method itself, due to the unavoidable correlation of different degrees among the selected evaluation indicators of flood control dispatching schemes, it cannot meet the relative independence requirements in the construction of the indicator system, and the highly correlated indicators There is a lot of repetition and interference in the reflected information, which makes the trend of the same index data linearly enhanced or weakened, which easily leads to distortion of the optimal results of...

Abstract

The invention discloses a reservoir group flood control scheduling scheme optimization method taking index correlation into consideration. The method comprises the following steps: constructing an index system for reservoir flood control scheduling schemes; measuring the degree to which the indexes in the index system are correlated by using a correlation analysis approach, converting the index system into a new index system of which the indexes are independent of each other by using a principal component analysis approach, and reducing the dimension of the original index system; calculating the weight of each index in the new index system by using an improved entropy weight approach; and analyzing the goodness of each scheduling scheme by taking the new index system and the weights of the indexes as input of a technique for order preference by similarity to an ideal solution. According to the method of the invention, the influence of index correlation to scheme screening is taken into consideration, and the research object is expanded from a single reservoir to a reservoir group. By adopting the method, the problem about index correlation in scheme selection can be solved effectively, and the dimension of the index system can be reduced. A powerful tool is provided for reservoir group flood control scheduling scheme optimization under the condition that the indexes are correlated.

Description

technical field [0001] The invention relates to a flood control technology, in particular to an optimal method for a flood control control scheme of a reservoir group. Background technique [0002] Flood control dispatching of reservoir groups is an important non-engineering measure to achieve the goal of flood control and disaster reduction through cooperation between reservoirs, and is closely related to social, economic, natural, ecological and other factors. At present, the more common practice is to generate a set of feasible schemes through the flood control dispatching model, from which the decision-maker selects a satisfactory scheme that comprehensively weighs the benefits of each target and puts it into decision-making. Flood control dispatching decision of reservoir group is a complex decision-making process with multi-objective, multi-attribute, multi-level and multi-stage. At the same time, real-time flood control scheduling is an irreversible real-time dynamic...
