Brief description of technology

The basin water transfer project is an important measure to alleviate the contradiction between water supply and demand in water-scarce areas and achieve rational allocation of water resources in the basin. The operation management and dispatch decisions of the water transfer reservoir are related to the safe operation and benefit of the project. It has cross-regional, variable-scale, and multi-goal and strong constraints, bringing a series of scientific and technical problems that need to be solved urgently. The multi-objective dispatch technology for large-scale inter-basin water diversion reservoirs mainly includes three systematic operation management technologies: dynamic control of reservoir water supply dispatch, nested power generation dispatch on multi-dimensional time scales, and multi-objective collaborative optimization of reservoirs.

comprehensive benefits

1) Danjiangkou Water Conservancy Project This technology has been implemented and applied in the Danjiangkou Reservoir of the Hanjiang River in Hubei Province. Danjiangkou Reservoir is a water supply source project of the Middle Route of the South-to-North Water Diversion Project. Its water supply objects include three parts: the middle and lower reaches of the Han River, the Tangxi Diversion Water Diversion Irrigation Area in Hubei Province and the first phase of the Middle Route of the South-to-North Water Diversion Project. By adopting this technology, Danjiangkou Reservoir has effectively coordinated complex water needs across regions, multiple objects and multiple users, effectively ensuring the middle and lower reaches of the Han River, northern Hubei region and Beijing, Tianjin, Hebei, Water demand of four provinces and cities in Henan. On the premise of ensuring the flood control safety of the hub and downstream flood control objects, under the unfavorable situation of continuous water supply in Danjiangkou Reservoir, the total benefits of water supply to the north achieved by the implementation of the project results in 2014 - 2015, 2015 - 2016 and 2016 - 2017 are approximately 225 million yuan. The Danjiangkou Hydropower Station increased its benefits by 11.49 million yuan through water conservation and increased power generation from 2015 to 2017. (2) Pankou Water Conservancy Project From 2015 to 2017, the Pankou Water Conservancy Project achieved water-saving additional electricity of 11.9 million kilowatt-hours, 12.4 million kilowatt-hours, and 11.8 million kilowatt-hours respectively. The total power generation benefits of this project from 2015 to 2017 are 1.37 million yuan.

technology maturity

Inter-basin water transfer is to transfer large amounts of water from watersheds to watersheds through large-scale artificial methods, in order to promote economic development in water-scarce areas and alleviate water-use conflicts in watersheds. After the 1950s, many countries such as the United States, the former Soviet Union, Canada, France, Australia, Pakistan, India, etc., have tried, and some have achieved huge benefits. Cross-basin water transfer has a long history in China. The Beijing-Hangzhou Grand Canal and the Lingqu Project connecting the Pearl River and the Yangtze River Basin are typical examples of cross-basin water transfer in history. The inter-basin water transfer project reconfigures water resources in the basin by changing the temporal and spatial distribution characteristics of water resources between river basins, effectively alleviating the contradiction between water supply and demand for production and life in water-scarce areas, and improving the ecological environment of water-receiving areas. With the frequent construction of water diversion projects, the upstream water supply has been significantly reduced, and the hydrological characteristics of the river network have changed greatly, resulting in large differences in the characteristic parameters and planning and design of large-scale inter-basin water diversion reservoirs, and the main operation and dispatch tasks are facing re-planning and adjustment; In addition, river basin water diversion is related to the development of industry and agriculture in adjacent areas, and it will also involve the redistribution of water resources in relevant river basins and possible changes in social living conditions and ecological environment. Therefore, there is an urgent need to carry out comprehensive utilization and dispatch methods for large-scale inter-basin water transfer reservoirs after the operation of the inter-basin water transfer project, which will help alleviate the increasingly prominent contradiction between water transfer from outside the basin and water use within the basin, as well as flood control, water supply, and power generation of large-scale inter-basin water transfer reservoirs. It is of great theoretical and practical significance.

technical applicability

The multi-objective dispatch technology for large-scale inter-basin water diversion reservoirs can be widely used in the fields of water resources management and water conservancy project management. It is especially suitable for the formulation of water supply dispatch plans for reservoir projects, the formulation of power generation dispatch methods for hydropower stations, and the formulation of multi-objective dispatch plans for comprehensive utilization reservoir projects. It has broad application prospects.
