Reservoir multi-objective optimization scheduling method based on cooperative game method

Abstract

The invention belongs to the technical field of reservoir optimal scheduling, and particularly relates to a reservoir multi-objective optimal scheduling method based on a cooperative game method, which comprises the following steps: step 1, calculating an environmental water demand process of a downstream river channel of a reservoir by applying a month-by-month improved flow duration curve; step2, establishing a single-person game model of a water resource management subject, and pursuing maximization of public interests of two subjects of power generation and environment; and step 3, establishing a multi-target cooperative game model of the water resource management subject, and pursuing the combination of collective benefits and personal benefits. Based on the cooperative game thought,the possibility of cooperation among all water consumption main bodies is discussed, a reservoir multi-target scheduling model is constructed, a certain theoretical basis is provided for unified management and unified protection of water resources, and individual benefits are considered on the basis that reservoir multi-targets are optimized on the basis that the overall benefits are optimized.

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
