A Reservoir Multi-objective Optimal Dispatch Method Based on Cooperative Game Method

Abstract

The present invention belongs to the technical field of optimal dispatching of reservoirs, and in particular relates to a method for multi-objective optimal dispatching of reservoirs based on the cooperative game method, comprising the following steps: Step 1, using the flow duration curve improved month by month to calculate the environmental water demand of the downstream channel of the reservoir Process; step 2, establish a single-person game model for water resources management subjects, and pursue the maximization of the public interests of power generation and the environment; step 3, establish a multi-objective cooperative game model for water resources management subjects, and pursue the combination of collective interests and personal interests . The present invention proposes a game idea based on cooperation, explores the possibility of cooperation among water users, and constructs a multi-objective scheduling model of the reservoir to provide a certain theoretical basis for the unified management and protection of water resources, and realize the multi-objective of the reservoir in the overall Benefits are optimized on the basis of taking into account individual interests.

Description

technical field [0001] The invention belongs to the technical field of optimal dispatching of reservoirs, and in particular relates to a multi-objective optimal dispatching method of reservoirs based on a cooperative game method. Background technique [0002] The current status of relevant research at home and abroad has found that the current research on the comprehensive utilization of water resources in river basins focuses on the optimal scheduling of multiple objectives such as flood control objectives, ecological environment objectives, and prosperity objectives, coordinates the water demand contradictions between different water users, and studies their master-slave relationships. It is a new challenge in the process of modern integrated water resources management to form a complete theoretical method of benefit coordination with mutual restriction relationship. In the case of conflicting and competing multi-objectives, multi-objective decision-making methods are ofte...

Problems solved by technology

In the case of conflicting and competing multi-objectives, multi-objective decision-making methods are often used for decision-making among water stakeholders, but this model can only obtain the non-inferior solution set of the problem. In the non-inferior solution, improve a The benefit of the objective function must be at the expense of the interests of other objective functions. When solving practical problems, the emphasis is on optimizing public interests while ignoring individual interests, and the existence of individual rationality will inevitably lead to conflicts in water resources management objectives in the basin. , resulting in behavioral rebellion, which makes it difficult to apply the global optimal solution in the traditional mathematical sense
