Abstract

The invention discloses a method for extracting a stage scheduling rule of a reservoir based on GRA and PSO-SVM. The method comprises the following steps of based on a historical actual scheduling result, firstly determining a decision variable and an influence factor attribute set, screening a staged influence factor based on GRA; determining a training sample and a testing sample, and constructing an SVM model; establishing a PSO-SVM simulating model based on the sample data, performing parameter calibration and verification on the SVM model by means of PSO; and determining a reservoir staged scheduling rule. The method has advantages of well inheriting a comprehensive benefit in an actual scheduling process, realizing a purpose of guiding the actual operation of the reservoir under a precondition of uncertain incoming water, and supplying theoretical basis and scientific supporting for actual operation of the reservoir.

Description

technical field [0001] The invention belongs to the technical field of reservoir dispatching in the field of water conservancy and hydropower, in particular to a method for extracting reservoir staged dispatching rules based on the combination of GRA and PSO-SVM. Background technique [0002] At present, the actual operation of reservoirs is still based on past experience. How to extract reservoir operation rules from actual operation experience is an important direction of research on reservoir operation and operation. The scheduling function is one of the manifestations of the current reservoir scheduling rules. Scheduling function extraction methods mainly include statistical regression method and intelligent algorithm. However, at present, most of the scheduling function studies have not carried out the screening operation of influencing factors, and so far, the research on the selection method of influencing factors is still in its infancy. There are many influencing ...
