Environmental-protection-oriented ecological reservoir capacity determination method for combined scheduling reservoir group

Abstract

The invention relates to an environmental-protection-oriented ecological reservoir capacity determination method for a combined scheduling reservoir group, and belongs to the technical field of environmental protection and comprehensive utilization of resources. Firstly, according to river ecological flow and water demand requirements regulated by a river management department, optimization objectives and constraint conditions are determined, a reservoir group ecological water utilization schedule optimization model is established, a weight set with multiple objectives is randomly generated and solved, and an optimal water supply scheme meeting a specific coordination value of the human social economy and ecology water lacking rate is determined; secondly, regulated reservoir capacities needed for water supplement of all reservoirs annually are calculated, and regulated reservoir capacities with the 90% guaranteed rate are selected; at least, regulated reservoir capacities without ecological objectives are worked out, and the difference value of the regulated reservoir capacities without ecological objectives is determined as the ecological reservoir capacity. The method has the advantages that the defect that ecological water supply is not taken into consideration in traditional reservoir group scheduling reservoir capacity setting is overcome, more reasonable reservoir capacity can be obtained according to the reservoir group ecological water utilization schedule optimization model and situational analysis, and implementation of reservoir group ecological scheduling rules is guaranteed.

Description

technical field [0001] The invention relates to a method for determining the ecological storage capacity of a joint dispatching reservoir group oriented to environmental protection, and belongs to the technical field of environmental protection and comprehensive utilization of resources. Background technique [0002] The joint dispatch of reservoir groups is an important means of water resources utilization and management in the basin. The operation and dispatch of traditional reservoir groups are aimed at maximizing social and economic functions such as flood control, water supply, and power generation. The deployment of these reservoirs has changed the natural process and laws of river hydrology, affecting the habitat and survival of fish and other aquatic organisms, and threatening the river ecosystem. With the increasing prominence of ecological environment problems, the water demand of river ecological environment has become an increasingly important task in reservoir r...

AI Technical Summary

Problems solved by technology

Because the ecological flow targets of each section of the rivers of the joint dispatching reservoir group are different, the ecological water supply of the upstream reservoir becomes the inflow of the downstream reservoir at the same time. So far there is no method for determining the ecological storage capacity of a group of reservoirs jointly dispatched
