Intelligent power grid engineering project comprehensive evaluation method based on AHP-GRA

The invention relates to an intelligent power grid engineering project comprehensive evaluation method based on AHP-GRA. With the development of intelligent power grid construction work, comprehensive evaluation of the current developing condition of intelligent power grid engineering programs becomes a very important issue. The method provided by the invention is aimed at problems of an conventional power grid comprehensive evaluation method, the conventional power grid comprehensive evaluation method is deepened and improved, and the deepened and improved conventional power grid comprehensive evaluation method is applied to the comprehensive evaluation of the intelligent power grid engineering programs. A gray association theory is utilized to solve problem that albinism function fuzzification errors exists in the conventional method. According to new characteristics of an intelligent power grid, a comprehensive evaluation system adaptive to the intelligent power grid is established, and combined with a Cobb-Douglas productive function, a technology advancement level is reflected through economic benefit contribution metrization. According to the invention, important indexes for evaluating the intelligent power grid, namely the developing level technology of the technology, are quantified, so that the indexes which can only be fuzzily analyzed originally can be quantitatively analyzed, the accuracy of comprehensive evaluation is improved, and comprehensive evaluation of the intelligent power grid engineering programs can be well performed.
