Abstract

The invention discloses a power distribution network diagnosis evaluation index weight assignment method based on fuzzy hierarchy and a CRITIC method, and the method comprises the following steps: carrying out the dimensionality reduction classification through employing the regression analysis of factors, removing redundant indexes, and screening out key indexes; performing layered subjective weighting on the screened indexes by using a fuzzy analytic hierarchy process; carrying out objective weighting on the screened indexes by utilizing a CRITIC method; and combining the weights obtained bysubjective weighting and objective weighting based on an optimal combination weight method to obtain the comprehensive weight of the screened index. Diagnostic analysis indexes of the power distribution network are comprehensively arranged, and typical indexes are selected to establish a diagnostic evaluation system, so that subsequent diagnostic evaluation work is facilitated. The power distribution network diagnosis evaluation index weight assignment method based on the fuzzy hierarchy and the CRITIC method can accurately assign the weight to each index, and the accuracy of an assignment result is high.

Description

technical field [0001] The invention relates to the technical field of power grid planning, in particular to a distribution network diagnosis and evaluation index weighting method based on fuzzy hierarchy and CRITIC method. Background technique [0002] A reasonable and accurate planning scheme can effectively guide decision makers to carry out purposeful and prioritized upgrades and transformations of the distribution network for weak links in the power grid, thereby improving the power supply reliability of the distribution network, improving the power supply capacity of the distribution network, and reducing Distribution network operation and maintenance costs and improve the quality of power supply. Before planning the distribution network, it is necessary to evaluate and diagnose the current situation of the distribution network to find out its weak links, so as to formulate an accurate planning plan in a targeted manner. At present, relevant research has been carried ...
