Water resource allocation method based on decomposition coordination idea of heuristic large system

Abstract

The invention discloses a water resource allocation method based on a decomposition coordination idea of a heuristic large system., which comprises the following steps of: performing water resource allocation on each calculation unit period by period by taking a natural river channel topological structure as a basis and taking the number of the calculation units as a cycle; taking the water shortage of each subsystem as heuristic information, considering the maximum supplementable amount of the riverway and the water supply capacity in the calculation unit, and performing compensation scheduling on the ecological flow of the cross section in the riverway after the calculation unit lacking water is processed; and following groundwater supplement configuration, groundwater water extraction capacity constraints and annual groundwater amount control in all time periods need to be considered at the same time, subsystem water shortage and regional groundwater consumption serve as heuristic information, and the groundwater consumption is configured. The water resource allocation method provided by the invention is high in calculation speed and high in calculation efficiency. Through the combination of the simulation model and the actual operation rule, the related constraints of the configuration problem can be better processed, the random optimization strategy is closer to the reality than the random optimization strategy of the heuristic intelligent algorithm, and the engineering practical value is better.

Description

technical field [0001] The invention belongs to the technical field of water resource allocation, in particular to a water resource allocation method based on the idea of ​​heuristic large-scale system decomposition and coordination. Background technique [0002] The problem of water resource allocation is a multi-level, multi-water source, high-latitude large-scale nonlinear programming problem, which has the characteristics of multi-decision variables, multi-objective, multi-constraint, and multi-coupling. The water conservancy projects involved in the allocation of water resources include the local river network water diversion and lifting projects of the surface water system, reservoir water storage projects, external water transfer projects, external water transfer projects, and groundwater system water pumping projects. A large number of water conservancy projects in the basin are in operation. The process and so on are the decision variables of the model. At the same...

[0004] The purpose of the present invention is to provide a water resource allocation method based on the idea of ​​heuristic large-scale system decomposition and coordination for the existing defects or improvement needs of the prior art. The idea of ​​decomposition and coordination disassembles the configuration object into basic calculation unit subsystems including water storage projects, water diversion projects, groundwater projects and other water resource utilization projects that calculate regional water supply, as well as natural rivers and water pipelines connecting each project; the configuration The problem is dismantled into three levels: local surface water resource allocation, joint optimal allocation of reservoirs, and groundwater replenishment allocation, taking subsystem water shortage (including subsystem regional water shortage and river ecological water shortage) and regional groundwater water consumption as Heuristic information coordinates various subsystems through heuristic strategies
