Reservoir water supply scheduling method based on SEM algorithm

Abstract

The present invention provides a reservoir water supply scheduling method based on an SEM algorithm. The method comprises the following steps of: the step 1, determining a water supply mode of a hydraulic project; the step 2, determining an initial multi-way water diversion and scheduling process of the hydraulic project; the step 3, searching a feature value: when [Delta]S is not equal to 0, increasing or decreasing water supply according to a certain step length, dividing the [Delta]S into G parts according to a diversion and scheduling water quantity ratio, dividing the G parts to corresponding water receiving users, and recalculating a reservoir total water supply; the step 4, calculating water quantity balance: performing scheduling calculation according to the total water supply process, determining the water level and the discharged volume process of the reservoir in each time period, allowing parameters of each time period to meet constraint conditions, determining whether a calculation end water level Zc is equal to an end water level control value Zg of a scheduling period in a hydropower station or not, if not, turning to a step 5, or else, turning to a step 6; the step5, correcting the end water level until Zc=Zg; and the step 6, according to the diversion and scheduling water quantity ratio requirement and the determined water receiving users, employing the SEM algorithm to perform solution, and taking the globally optimal solution of the SEM algorithm as the diversion and scheduling water process result of each water receiving user.

Description

technical field [0001] The invention belongs to the fields of optimal configuration of water sources and optimized dispatching of water conservancy projects, and in particular relates to a reservoir water supply dispatching method based on SEM algorithm. Background technique [0002] Inter-basin water transfer reconfigures cross-basin water resources by changing the temporal and spatial distribution characteristics of water resources between basins, effectively alleviating the contradiction between water supply and demand for production and life in water-shortage areas, and improving the ecological environment of water-receiving areas. However, with the frequent construction of inter-basin water transfer projects, the contradiction between water transfer outside the basin and water use within the basin, and the contradiction of competitive water use among different regions and departments will become increasingly prominent. For more than half a century, experts and scholars ...

AI Technical Summary

Problems solved by technology

At present, domestic and foreign studies mostly focus on the analysis of the impact of inter-basin water diversion on the hydrology and ecology of the downstream of water sources, and less quantitative research on the role of downstream control reservoirs in water sources can play in inter-basin water transfer.

[0004] Therefore, when dealing with the optimal allocation of cross-basin water resources, the current method is difficult to give full play to the comprehensive benefits of controlled reservoir regulation and storage in the water source area, and cannot take into account the water transfer outside the basin and the water demand within the basin.
