Reservoir flood-control dispatching optimization method based on flood-control dispatching data adaptive control

Abstract

The invention discloses a reservoir flood-control dispatching optimization method based on flood-control dispatching data adaptive control and relates to the technical field of reservoir flood-control dispatching. The method comprises the following steps: establishing a target reservoir general flood-control dispatching chart; establishing a flood-control dispatching model; determining an objective function; according to the number of dispatching lines of the general flood-control dispatching chart and the number of inflection points of each dispatching line, obtaining the total number of optimization variables required by the general flood-control dispatching chart; according to the determined objective function and the optimization variables, carrying out optimization calculation through an NSGA-II algorithm, and carrying out Pareto non-dominated solution analysis on the objective function to obtain an optimized general flood-control dispatching chart; and carrying out flood control service calculation through the optimized general flood-control dispatching chart. Reservoir flood-season dispatching with the general flood-control dispatching chart being introduced can make full use of incoming water of a reservoir while ensuring safety of downstream flood control, thereby improving flood utilization efficiency, and meanwhile, improving solution efficiency of an optimization model.

Description

technical field [0001] The invention relates to the technical field of flood control dispatching of reservoirs, in particular to an optimization method for flood control dispatching of reservoirs based on adaptive control of flood control dispatching data. Background technique [0002] Reservoir flood control scheduling refers to the use of the reservoir's regulating and storage capacity by human beings to store and discharge the inflow runoff in a planned way according to the inflow and storage conditions of the reservoir, and on the premise of ensuring the safety of the reservoir itself and downstream flood control, so as to achieve benefits and eliminate harms. To ensure the safety of people's lives and property and the smooth development of the national economy. At present, traditional reservoir flood control often adopts the method of limiting the reservoir capacity to the flood-limited water level during the flood season. However, the flood regulation flow during the f...

Problems solved by technology

[0004] 1. The existing dynamic control method of flood limit water level of the reservoir is applied to the real-time dispatching stage of the reservoir. The dispatching rules are complicated and inconvenient to operate in actual application

[0005] 2. The existing reservoir scheduling diagram is more intuitive and easy to apply, and has been widely used in reservoir prosperity scheduling. However, the existing reservoir scheduling diagram cannot be applied in flood control scheduling

[0006] 3. Introduce the incoming water from the reservoir in the flood control dispatching map, but, due to the flood control dispatching Figure 1 Generally, it is designed by the researchers themselves. It is not as good as the uniform and fixed shape of the Xingli dispatching map. When using the flood control dispatching map that introduces water from the reservoir, the user needs to study it first and then organize it into the shape required by the user. Therefore, it is not convenient to use. The problem
