Embodiment

[0105] This embodiment takes the Heihe River Basin as the application object. According to water demand and economic structure, the Heihe River Basin is divided into three sections from top to bottom: the upper reaches above Yingluo Gorge are the main source of runoff and the main hydropower development base, including the first level of Longshou and Longshou Level 2, Xiaogu Mountain, Dagu Mountain, Erlong Mountain, Sandao Bay, Baoping River, Huangzang Temple; between Yingluo Gorge and Zhengyi Gorge is the middle reaches, and there are many irrigation areas along the coast, which are the main water areas of the basin; Below Zhengyi Gorge is the downstream, where precipitation is scarce and the ecology is fragile, and it is the main water-consuming area. The node map of the Heihe River Basin is as follows: image 3 shown.

[0106] Water demand in the Heihe River Basin mainly includes irrigation in the middle reaches and ecological water demand in the downstream. According to...

Abstract

The invention discloses a surface water and underground water combined dispatching optimization method based on an improved pollen algorithm. The method comprises: firstly, taking the maximum comprehensive objective of power generation, irrigation and ecology of a reservoir as an optimization objective, establishing an objective function of the reservoir optimization objective, and constraint conditions of the objective function comprising a water balance constraint, a node water quantity constraint, an underground water period water taking constraint, a reservoir water level constraint, a reservoir discharge constraint and a power station output constraint which are taken as constraint conditions; secondly, introducing a computer parallel technology to improve a pollen algorithm, and carrying out optimization calculation on the objective function to obtain power generation quantity, warehouse entering and exiting runoff, underground water taking rate and optimal reservoir water level.The surface water and underground water combined dispatching optimization method based on the improved pollen algorithm has important practical significance and application value for enriching reservoir group optimization dispatching methods, improving surface water and underground water combined dispatching benefits of northwest arid regions and improving water resource comprehensive utilizationbenefits and regional ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of joint scheduling optimization of surface water and groundwater, and in particular relates to a joint scheduling optimization method of surface water and groundwater based on an improved pollen algorithm. Background technique [0002] At present, the water resources in the arid areas of our country are relatively short, which has seriously affected the sustainable development of the arid areas. At this stage, the joint dispatching of surface water and groundwater has become an important measure to solve the shortage of water resources in arid areas. As an important part of the joint regulation of groundwater and surface water, the operation mode of the reservoir has received special attention; however, the optimal regulation of the reservoir is nonlinear, high-dimensional and complex. At present, the optimal dispatching methods of reservoirs are mainly divided into traditional methods and optimization met...
