An analysis method for multi-objective mechanism and optimal operation scheme of reservoir group

Abstract

The invention discloses a reservoir group multi-objective action mechanism and optimized dispatching scheme analysis method. The reservoir group multi-objective action mechanism and optimized dispatching scheme analysis method comprises the steps that first, on the basis of a reservoir group system of a generalization study area, a five-objective optimized dispatching model of power generation, water supply, ecology, shipping and flood control of a reservoir group is constructed; a objective function and a constraint condition used in the model are determined, the flood control requirements are converted into a flood season water level constraint condition, the actually measured flood data or the designed flood process are used as model input, an intelligent optimization algorithm is usedfor solving the model, and the two-to-two objective two-dimensional planar mapping is carried out on solution results; the action relationship between the objectives under the incoming water conditionis subjected to nature-determining based on the relationship presented by the two-dimensional planar mapping, combined with the target function value corresponding to a selected representative point,the strength of the action relationship between the objectives under the incoming water condition is analyzed, discrimination of the action relationship between the objectives is carried out, and a reservoir group dispatching method is obtained. The reservoir group multi-objective action mechanism and optimized dispatching scheme analysis method provides reference and basis for the optimized dispatching of the reservoir group considering the benefits of power generation, water supply, ecology and shipping meanwhile, and high practicability and wide applicability are achieved

Description

technical field [0001] The invention relates to a water resources evaluation management and reservoir dispatching scheme guidance method, in particular to a reservoir group multi-objective optimization interaction mechanism and an optimization dispatching scheme analysis method. Background technique [0002] With the continuous development of my country's hydropower system, hydropower resources have received more and more attention and attention. At the same time, with the development of the regional economy, the tasks undertaken by the reservoir are no longer limited to providing power support. The operation of the reservoir not only ensures the flood control safety of the river, but also plays various roles such as power generation, water supply, ecological environment maintenance, and navigation status. In the power system, hydropower stations are used for peak regulation and frequency regulation due to their cleanliness and flexible switch scheduling. However, due to th...

Problems solved by technology

At present, the requirements for the comprehensive development of reservoirs are getting higher and higher, but there are few studies on the contradictions faced by reservoirs when they accomplish these goals, and there is also a lack of a more intuitive grasp and analysis of internal contradiction mechanisms, which makes the reservoir and reservoir group system in A large amount of waste of energy and resources is generated during the operation, which is contrary to the development purpose of my country's comprehensive resource development
