Optimal site selection method and device for decentralized wind farms based on fuzzy hierarchy process

Abstract

An optimal site selection device for a distributed wind power plant based on a fuzzy analytic hierarchy process comprises a DSP (Digital Signal Processor) module, a keyboard input module, a liquid crystal display module, a communication module and a host computer. An optimal site selection method for the distributed wind power plant based on the fuzzy analytic hierarchy process comprises the following steps: dividing candidate wind energy resource zones in a region rich in wind energy resources, determining an evaluation index system for the site selection of the wind power plant, determining the hierarchical structure of a scheme for the site selection of the wind power plant, judging the cognition degrees of experts on selected sites for the wind power plant by an expert group judgment and group decision method to obtain the cognition degree parameters of all the experts, and constituting a criterion layer judgment matrix and an index layer judgment matrix for the site selection of the wind power plant; and finally ranking the candidate wind energy resource zones by advantages and disadvantages and determining one site for the wind power plant. Compared with the traditional analytic hierarchy process for site selection, the method has the advantages that factors are fully considered, the examination and the regulation of the consistency of the judgment matrixes are simple, easy, scientific and reasonable, and results are scientifically analyzed. The device has the advantages that through the operation processing process of the DSP, the site selection period can be shortened, and the site selection efficiency can be increased.

Description

technical field [0001] The invention belongs to the technical field of wind farms, in particular to a method and device for optimal site selection of distributed wind farms based on fuzzy hierarchy analysis. Background technique [0002] Wind energy is a conversion form of solar energy on the earth, and it is a renewable energy source that does not produce any pollution emissions. Wind power has great development prospects in the utilization of renewable energy, and the site selection of wind farms, as the preliminary project of wind farm construction projects, plays a vital role in the success or failure of wind farm construction and its future benefits. [0003] Wind farm site selection is divided into macro site selection and micro site selection. The process of macro site selection for wind farms is to select a site with abundant wind energy resources and the most valuable after a comprehensive inspection of meteorological conditions and other aspects in a relatively lar...

AI Technical Summary

Problems solved by technology

[0007] 1. Considering the influence factors of macro site selection is not comprehensive

Some ignore factors such as environment and safety, some ignore traffic conditions, etc.

[0008] 2. It is very difficult to test whether the judgment matrix is ​​consistent

When the order n is large, calculate λ accurately max The workload is very large, and the "curse of dimensionality" problem often occurs when solving

[0009] 3. Judgment criteria for testing the consistency of the judgment matrix: C.R.<0.1 lacks scientific basis

[0010] 4. When the judgment matrix is ​​not consistent, it is troublesome to adjust to consistency

[0011] 5. The result analysis method is unscientific, and does not consider the particularity of each evaluation index, because some indexes are bigger and better, and some indexes are smaller and better, without uniform dimensions
