[0003] For the optimal allocation of water resources in a single reservoir-multi-pumping station system that directly replenishes the reservoir, although the water source conditions are sufficient, since the reservoir is replenished by multiple water pumping stations, how to ensure the water supply in the water receiving area during the actual operation of the system? Under sufficient conditions, it is an important issue that cannot be ignored to reduce the overall energy consumption of the replenishment pumping station group and save project operating costs

Embodiment Construction
[0078] Such as figure 1 As shown, the goal of the single-reservoir-multi-station system with direct reservoir replenishment is to minimize the sum of the squares of the differences between the reservoir water supply and the water demand in the receiving area at each period of the year, and the reservoir water supply in each period of the year is the decision variable. The total annual water supply (that is, the sum of the total annual water supply of the reservoir and the total annual pumping water of each pumping station), reservoir dispatching criteria, reservoir water balance, and the minimum energy consumption of the joint operation of the supplementary pumping station group are the constraints. Establish a single-station-multi-station system water resources optimal dispatching model for direct replenishment under sufficient irrigation conditions.

The invention discloses a single reservoir-multistation system water resource optimization configuration method for direct reservoir supplementation under the condition of full irrigation, and the method comprises the steps: building a single reservoir-multistation system water resource optimization configuration mathematic model for direct reservoir supplementation under the condition of full irrigation; employing a single reservoir-multistation big system one-dimensional dynamic planning method based on the reservoir supplementation pump station group subsystem decomposition-dynamic planningaggregation, and obtaining the minimum water shortage of a water intake region in a certain water supply period, the optimal water supply and surplus water volume of a corresponding reservoir in eachtime period, and the water supplementation process of each reservoir supplementation pump station. The method is of importance theoretical significance to the optimization configuration of water resources of an irrigation region of a plain reservoir, and has the actual practical value for the optimization configuration of water resources of the irrigation region of the plain reservoir.
Description
technical field [0001] The invention relates to a method for joint operation scheduling of a single reservoir and a plurality of replenishment pumping stations under sufficient irrigation conditions, and belongs to the technical field of optimal allocation of water resources in irrigation areas. Background technique [0002] At present, due to the uneven distribution of water resources in time and space, the economic and social development of many areas has been restricted. For irrigation areas with sufficient irrigation conditions, under the limited total amount of water resources and the scale of water source projects, the goal of maximizing the comprehensive benefits of water use is to strengthen regional The unified scheduling and management of water resources, the use and adjustment of water conservancy projects in the irrigation system as a unified whole, and the use of existing projects (such as joint scheduling and operation of reservoirs and pumping stations) to make...
