[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
[0079] Such as figure 1 As shown, the goal is to minimize the sum of squares of the difference between the water supply volume of the reservoir at each time period of the year and the water demand of the water-receiving area in the single-reservoir-multi-station system that directly replenishes the reservoir. The total annual water available (that is, the sum of the total annual available water of the reservoir and the total annual water diversion and withdrawal of each pumping station), reservoir scheduling guidelines, reservoir water balance, and minimum energy consumption for joint operation of replenishing pumping stations are constraints. Establish a single-storage-multi-station system water resource 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 the joint operation and dispatching of a single reservoir and a plurality of replenishment pumping stations under sufficient irrigation conditions, and belongs to the technical field of water resources optimal allocation 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 is to maximize the comprehensive benefits of water use. The unified dispatch and management of water resources, the use and adjustment of the irrigation system's water conservancy projects as a unified whole, and the use of existing projects (such as the joint dispatch operation of reservoirs and pumping stations) to make them play a greater role is...
