Abstract
Reasonable evaluation of distribution network operation performance can provide reference for distribution network planning, transformation and operation optimization. This has an important impact on the security and stability of the distribution network. Based on related indexes, a method of distribution network operation level evaluation is proposed based on combination weighting and improved grey correlation. Firstly, the correlation coefficient of each evaluation index of distribution network operation performance is introduced, and the combined weight method is used to modify the comprehensive weight of each index, and then the Comprehensive Evaluation Index of each region is obtained, thus, the weak area of distribution network operation performance is identified and the target area in urgent need of transformation is obtained. Then, the mean difference influence coefficient is introduced to improve the traditional grey correlation method, and the correlation degree between the influencing factors of distribution network operation performance and the Comprehensive Evaluation Index is obtained, so as to get the influence degree of each influencing factor on the distribution network operation performance, determine the renovation plan. Finally, the effectiveness and superiority of the proposed method are verified by an example.
