Embodiment 1

[0046] Such as figure 1 As shown, in this embodiment, a method for formulating an optimal scheduling plan for water volume of a cross-basin water transfer project considering the hydraulic response characteristics is provided, including the following steps

[0047]S1. According to the hydraulic connection and hydraulic response characteristics of each object of the water transfer project, construct a generalized network diagram of the cross-basin water transfer project model;

[0048] S2. On the basis of the generalization diagram of the model network, construct a ten-day water quantity optimal dispatching model of the water diversion project and use the differential evolution algorithm ((DE algorithm)) to realize the efficient solution of the model;

[0049] S3. According to the optimal solution obtained by solving the model, formulate an optimal dispatch plan for the ten-day water quantity of the water diversion project.

[0050] In this embodiment, step S1 is specifically ...

Embodiment 2

[0078] Such as Figure 3 to Figure 6 As shown, in this embodiment, taking the Yangtze River to Huaihe River project as an example, according to the steps described in the present invention, the ten-day water volume optimization dispatch plan of the river diversion project is compiled.

[0079] The project of diverting the Yangtze River to the Huaihe River is a major cross-basin and trans-regional strategic water resources allocation and comprehensive utilization project. It connects the two major water systems of the Yangtze River and the Huaihe River. The project can be subdivided into the water diversion line from the Yangtze River to Jichao, the communication line between the Jianghuai River and the northward transmission line of the river and water. The generalized diagram of the overall project is as follows image 3 shown. In the Yinjiang Jichao section, Caizi Lake Zongyang Pumping Station and Xihe Fenghuangjing Station are used as the gates of the river diversion, whic...

Abstract

The invention discloses a cross-basin water transfer project ten-day water optimization dispatching plan preparation method considering the hydraulic response characteristics, including constructing a cross-basin water transfer project model network generalization diagram according to the hydraulic connection and hydraulic response characteristics of each object of the water transfer project ; On the basis of the model network generalization diagram, construct the optimal dispatching model of ten-day water quantity of water diversion project and use the differential evolution algorithm to realize the efficient solution of the model; according to the optimal solution obtained by solving the model, formulate the optimal dispatching plan of ten-day water quantity of water diversion project. The advantages are: fully considering the hydraulic response characteristics of each object in the water transfer project, it can realize the refined simulation of water level, flow and pump station energy consumption in the ten-day dispatching process of the water transfer project; The regulation and storage capacity of the lakes along the water transfer project, optimize the ten-day water transfer process, balance the multi-dimensional goals of water supply shortage, water transfer energy consumption, unbalanced water volume of lakes, etc., in order to prepare the optimal ten-day water volume optimization scheduling plan for cross-basin water transfer projects.

Description

technical field [0001] The invention relates to the technical field of optimal dispatching of water resources, and in particular to a method for formulating a ten-day optimal dispatching plan for cross-basin water diversion projects considering hydraulic response characteristics. Background technique [0002] The inter-basin water diversion project is an effective means to solve the uneven spatial distribution of water resources and a major measure to rationally utilize regional water resources and ensure sustainable economic and social development. Among them, the water volume dispatching model is the basis for formulating the water volume dispatching plan of the cross-basin water transfer project. According to different time scales, the water dispatching model is divided into the annual and monthly water dispatching model and the ten-day water dispatching model, which respectively support the annual and monthly water dispatching plan of the water transfer project. And the ...
