Abstract

The invention discloses a power distribution network investment evaluation method and system based on a grey analytic hierarchy process, and belongs to the technical field of power distribution network production investment evaluation. According to the power distribution network investment evaluation method based on the grey analytic hierarchy process, indexes are divided by adopting a three-level hierarchical method, and meanwhile, the first-level investment evaluation weight AU of a power distribution network production investment evaluation index Ui and the second-level investment evaluation weight AV of a power distribution network production investment evaluation index Vij are determined; the method is used for reflecting the importance degree of the power distribution network production investment evaluation indexes Ui and Vij to the target W, then comprehensive evaluation is carried out on the project, the scheme is scientific and reasonable, and different influences of indexes of different levels on project evaluation can be fully considered; and meanwhile, each individual evaluation index is scored one by one, and the influence difference of each index on the technical improvement project evaluation is distinguished, so that the accuracy of the technical improvement project evaluation method is effectively improved, the effectiveness and accuracy of the technical improvement project evaluation are ensured, and the method is convenient to popularize and use.

Description

Technical field [0001] The present invention relates to a distribution network investment evaluation method and system based on gray hierarchical analysis, belonging to the production technology of distribution network. Background technique [0002] China Patent (Publication No.: CN110969532A) Publicly Open a Power Grid Production Technical Reform Project Investment Effect Evaluation Method [0003] The present invention discloses a method of investment effective assessment of the power grid production technique, including the following steps: analysis of the influence factor of investment in the production and technical reform of the grid, build an assessment index system; based on the construction of the assessment index system, adoption of entropy right-gray relationship method The TOPSOS method calculates relative closer, with the optimal ideal solution relative to the degree, the larger the value, the finer the evaluation item, and the item can be given priority. The above-m...
