Abstract

The present invention discloses a complicated reservoir group common water supply task distribution method. The method comprises the following steps of 1 according to the topology structure of a reservoir group and the distribution condition of a common water supply objective, hierarchically establishing a virtual aggregated reservoir, and drawing a corresponding joint scheduling graph; 2 determining a common water supply task distribution strategy aiming at the parallel and series two topology structures separately; 3 establishing an objective function of a joint water supply scheduling model; 4 adopting a multi-objective evolution algorithm to optimize the objective function of the joint water supply scheduling model, thereby obtain a relative optimal joint scheduling rule. The complicated reservoir group common water supply task distribution method of the present invention can realize the complicated reservoir group joint water supply uniform scheduling, can capture the space-time difference of the reservoir runoffs, fully plays the reservoir's capacity compensation and hydrology compensation roles of the reservoir group, enables the optimization configuration capability of a system to the water resource to be improved furthest, is suitable for being applied to the complicated reservoir group joint scheduling, and can be widely used for the complicated reservoir group common water supply task distribution.

Description

technical field

[0001] The invention belongs to the technical field of joint dispatching of reservoir groups, and in particular relates to a method for allocating common water supply tasks of complex reservoir groups. Background technique

[0002] my country's large-scale river basins have formed or are forming an overall layout of joint development and utilization of reservoir groups. Optimal scheduling of joint water supply for reservoir groups is a nonlinear multi-objective optimization problem with complex constraints. is increasing, the difficulty of realizing its optimal scheduling is also increasing. At present, the method of virtualizing reservoir groups as aggregated reservoirs to make water supply decisions is regarded as one of the best methods for joint scheduling of reservoir groups. Although this method can comprehensively consider the water storage status of the reservoir group, accurately locate the water supply capacity of the system, and more objectively de...

Embodiment Construction

[0025] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0026] A method for assigning common water supply tasks of complex reservoir groups, comprising the following steps:

[0027] In the first step, according to the topological structure of the reservoir group and the distribution of common water supply targets, construct virtual aggregated reservoirs hierarchically, and compile the corresponding joint dispatching diagram.

[0028] as attached figure 1 The water supply diagram of the complex reservoir group shown in the figure shows that there are many water users and the water supply method is relatively complicated. The entire water supply system of the reservoir group is composed of three subsystems: a reservoir and the downstream section of a reservoir are subsystem A, b reservoir, b-c reservoir section, c The downstream section of the reservoir and ...
