Problems solved by technology
However, with the rapid development of social economy, more and more factors need to be considered in the optimal allocation of water resources, especially for complex water resource systems, in the process of constructing and solving the optimal allocation model, the problem of dimensionality disaster is prone to occur, so it is necessary to The system performs partition processing to achieve effective dimension reduction of the system to improve computing efficiency
At the same time, the previous water resources optimal allocation model usually set the maximum total water supply guarantee rate in the whole region as the social benefit goal, and it is difficult to ensure the fairness of water user benefits in each region
In addition, in terms of solving the optimal configuration model, the Gray Wolf Optimization Algorithm (GWO) proposed by Mirjalili et al. (DE) and genetic algorithm (GA) and other optimization algorithms, but there are also defects such as slow convergence speed, weak global search ability, and easy to fall into local optimum.

The invention discloses a complex water resources system optimization configuration method based on the theory of "zoning-grading", the steps are as follows: firstly obtain the basic information data of the water resources system, secondly generalize the complex water resources system; Divide the entire water resource system into zones based on the water supply relationship between rivers, water pipelines, and water plants, and establish a digital matrix of hydraulic relationships in different zones; finally, construct and solve a multi-level water resource system optimal configuration model according to the type of water supply source A collection of reasonable optimization configuration schemes. The invention can realize the simplification of the complex water resources system, and provide a new approach for efficient utilization of water resources.
Description
technical field [0001] The invention belongs to the field of water resource allocation, and in particular relates to a complex water resource system optimization allocation method based on the theory of "division-grading". Background technique [0002] In order to solve the shortage of water resources caused by the uneven distribution of water resources in time and space, carrying out research on the optimal allocation of water resources can improve the utilization rate of water resources, which has obvious social and economic benefits. However, with the rapid development of social economy, more and more factors need to be considered in the optimal allocation of water resources, especially for complex water resource systems, in the process of constructing and solving the optimal allocation model, the problem of dimensionality disaster is prone to occur, so it is necessary to The system performs partition processing to achieve effective dimension reduction of the system to im...
