Abstract

The invention provides a comprehensive evaluation method for sustainable development of smart power grid based on AHP-PCA algorithm. In the first k months before the evaluation method is put into use, based on the analytic hierarchy process (AHP), all the evaluation factors are statically weighted and are scored according to the operation of the smart power grid so as to establish the evaluation index WAHP of AHP. After K-month operation of the evaluation method, based on the principal component analysis, all the evaluation factors were dynamically weighted from k + 1 month, and the effective principal components are sorted out to establish the evaluation index WPCA of PCA. The evaluation index WPCA of PCA is then combined with the evaluation index WAHP of AHP to serve as the evaluation index WAHP for evaluating the sustainable development of the smart power grid. The invention combines the analytic hierarchy process and the principal component analysis method to solve the problem of error caused by subjective difference in smart power grid evaluation and the problem that the principal components are void of meaning despite contained information so as to provide an effective management scheme for the sustainable development of a smart power grid.

Description

technical field [0001] The present invention relates to a technology in the field of smart grid evaluation, in particular to a comprehensive evaluation method for smart grid sustainable development based on AHP (Analytic Hierarchy Process) method and PCA (Principal Component Analysis, principal component analysis) method. Background technique [0002] The smart grid has become the development trend of the power system in the next few decades, and its sustainable development capability is the core element to measure the development degree of the grid construction. Therefore, the comprehensive evaluation research on the sustainable development of the smart grid is of great significance to the construction and development of the smart grid. [0003] Hierarchy analysis and principal component analysis are commonly used analysis methods in smart grid evaluation. In order to meet the needs of sustainable development evaluation, it is required that the evaluation index of the analy...
