Embodiment

[0064] refer to figure 1 , the method for extracting the aggregation and decomposition scheduling rules for large system reservoir groups described in this embodiment, the method includes:

[0065] S1, divide multiple sub-basins according to the distribution characteristics of the main and tributary streams of the target watershed, and obtain the basic attributes of each reservoir on any sub-basin A;

[0066] S2, classify all the reservoirs on the sub-basin A according to their tributaries or according to the basic attributes of the reservoirs, and then aggregate each type of reservoir to obtain one or more virtual aggregated reservoirs of the sub-basin A;

[0067] S3, for any virtual aggregated reservoir A′, select the dispatching rule form of the virtual aggregated reservoir A’ according to the characteristic attributes of the sub-watershed A, and then determine the parameters to be optimized; if the sub-watershed A is a simple watershed, the virtual aggregated reservoir A’ ...

Abstract

The invention discloses an aggregation-decomposition scheduling rule extracting method for large-system reservoir groups, and relates to the technical field of large-system reservoir group optimal scheduling. The method includes the steps that basic attributes of each reservoir on a random sub-basin A of a target basin are obtained; the reservoirs on the sub-basin A are aggregated into one or more virtual aggregation reservoirs; according to characteristic attributes of the sub-basin A, a scheduling rule form of the virtual aggregation reservoirs A' is selected, and parameters which need to be optimized are determined; according to the characteristic attributes of the sub-basin A and characteristic attributes of the reservoirs on the sub-basin A, a decomposition method of the virtual aggregation reservoirs A' is determined; constraint conditions are set, through the simulating of the scheduling rule form and the decomposition method, target function values of the parameters which need to be optimized are obtained, the parameters which need to be optimized are optimized, and a target-basin series-parallel reservoir-group scheduling rule set is obtained. According to the aggregation-decomposition scheduling rule extracting method for the large-system reservoir groups, multi-target large-system series-parallel reservoir-group joint optimization scheduling is completed, and scientific bases and technical support are provided for actual scheduling.

Description

technical field [0001] The invention relates to the technical field of optimal scheduling of large system reservoir groups, in particular to a method for extracting aggregation and decomposition scheduling rules for large system reservoir groups. Background technique [0002] Reservoirs are an important means for humans to utilize water resources. With the increase in the number of reservoirs, how to effectively dispatch and utilize large-scale system reservoirs to achieve flood control, power generation, shipping, water supply and other functions and tasks has become a research hotspot in reservoir dispatching. The joint optimal dispatching technology of reservoir groups is one of the necessary means to realize the normal operation of reservoir groups. The operation of the reservoir group is managed by the joint optimal dispatching technology of the reservoir group, which has the advantages of less investment, great benefit, high demand and broad prospect. [0003] In CN 1...
