Embodiment 1

[0051] Such as figure 1 As shown, in this embodiment, a method for formulating an urban raw water dispatching plan for comprehensive utilization of multiple water sources and multiple objectives is provided, including the following steps,

[0052] S1. Generalize the urban multi-source water supply system, and perform constraint processing on the generalized virtual water supply lines, so as to build an urban raw water dispatching model that considers the balance between supply and demand of each water plant and takes into account the rational utilization of multiple water sources;

[0053] S2. Set the objective function and constraint conditions for the urban raw water dispatching scheme compilation model constructed in step S1, and based on the priority ranking of each objective function set, under the constraint conditions, use the multi-objective optimization algorithm of the step-by-step optimization algorithm The optimization of each objective function of the urban raw wa...

Embodiment 2

[0092] Such as Figure 2 to Figure 5 As shown, in the present embodiment, take the water supply system of Beijing Water Supply Group as an example, according to the method of the present invention, compile the annual water transfer plan of 7 water sources and 12 water plants, and relevant water source data are as shown in Table 1, water plants The data are shown in Table 2. The generalized topological map of the water supply network of municipal water plants in Beijing is as follows: figure 2 shown.

Abstract

The invention discloses an urban raw water scheduling scheme compilation method for multi-water-source multi-target comprehensive application. The method comprises the following steps: S1, generalizing an urban multi-water-source water supply system, and carrying out constraint processing on a generalized virtual water supply line to construct an urban raw water scheduling scheme compiling model considering supply and demand balance of each water plant and reasonable utilization of multiple water sources; and S2, setting target functions and constraint conditions for the urban raw water scheduling scheme compiling model constructed in the step S1, and on the basis of priority ranking of all the set target functions, carrying out step-by-step optimization on all the target functions of the urban raw water scheduling scheme compiling model by using a multi-target optimization algorithm of a step-by-step optimization algorithm under the constraint conditions, and obtaining an optimal urban raw water scheduling scheme. The method has the advantages that external water utilization is preferentially achieved, local surface water utilization is balanced, local underground water pressure mining is reduced, a multi-water-source urban water supply system is fully and reasonably utilized, the water supply guarantee rate of the urban water supply system is increased, and water supply safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water resource management, in particular to a method for formulating an urban raw water dispatching scheme for comprehensive utilization of multiple water sources and multiple objectives. Background technique [0002] The compilation of urban raw water dispatching scheme is an important task in the macro-control of urban water resource allocation. In the past, urban raw water dispatching only considered the supply and demand balance indicators of each water plant when making plans, and lacked the optimal management concept of comprehensive deployment of various water sources. With the gradual expansion of urban clusters and the gradual enrichment of urban functions, the demand for guaranteed water supply in various industries in the city is gradually increasing, and the local water resources in the city are difficult to meet the corresponding needs, and the external water transfer project is gradually int...
