Multi-objective optimization scheduling method suitable for coastal region water resources

Abstract

The invention discloses a multi-objective optimization scheduling method suitable for coastal region water resources. The method comprises the steps of generalizing a water resource system according to the characteristics of a coastal region; determining an objective function and constraint conditions, and establishing a multi-water-source multi-objective multi-user coastal region water resource optimization scheduling model; using a multi-objective particle swarm optimization algorithm to solve a multi-objective optimization problem based on Pareto dominance, and constructing a non-inferior solution set of a coastal region water resource optimization scheduling model by judging a dominance relation; and acquiring an optimal scheme by taking the minimum Euler distance from the ideal solution as the criterion. According to the method, the current situation of engineering type and water quality type mixed water shortage in the coastal region is taken as the background; The invention provides an optimal scheduling method for combined water supply of a plain reservoir, a plain river network and a long-distance water transfer project, which conforms to the characteristics of the coastalregion, realizes a water resource scheduling pattern of quality-based water supply and excellent water utilization, and has practical significance for improving the situation of water resource shortage of the coastal region.

Description

technical field [0001] The invention belongs to the technical field of water resource scheduling in the field of water conservancy and hydropower, and in particular relates to a multi-objective optimization scheduling method suitable for water resources in coastal areas. Background technique [0002] The original water resources optimal dispatching originated from the reservoir optimal dispatching problem proposed by Masse in the 1940s. Compared with foreign countries, domestic research on water resources dispatching started relatively late. However, due to the complexity of my country’s water resources and the contradiction between supply and demand Sharpness. Since the 1980s, the research on optimal allocation and dispatch of water resources in my country has been highly valued and has developed rapidly. The specific performance is that the model built has changed from simple to complex, the optimization target has changed from single to multi-objective, and the research obj...

AI Technical Summary

Problems solved by technology

At present, there is no relevant research on the water supply joint dispatch of the local plain river network, plain reservoir group, and long-distance water transfer project in the coastal area.

[0003] The terrain in the coastal area is flat and low-lying, so it is not suitable to build large-scale water storage projects. The storage capacity of the river channel is extremely limited, resulting in a large amount of precipitation runoff that cannot be intercepted and stored in vain.
