Evaluation of Distribution Network Status Based on Principal Component Analysis and Correspondence Analysis

Abstract

[Introduction] In order to evaluate the distribution network more reasonably and objectively. [Method] This paper established a scientific and reasonable evaluation system of distribution network from these five aspects, and extracted the implicit data of distribution network indicators by principal component analysis. The internal relationship made the weight of each index objectively and reasonably calculated. Fuzzy comprehensive evaluation method was applied to evaluate the whole distribution network situation more comprehensively and accurately, in which the interval of actual data scoring results was divided and the evaluation grade standard of quantitative index in the fuzzy comprehensive evaluation method was unified. [Result] So as to solve the problem, fuzzy comprehensive evaluation method can not deal with a large number of quantitative index data, which reduced the computational complexity, while maintaining the accuracy of the evaluation results. [Conclusion] We demonstrate the evaluation of distribution network more real, reasonable and reliable. The example analysis of Jiangxi distribution network shows that the evaluation method is scientific and effective.
