Clustering and comprehensive evaluation model of distribution network projects and practical research

Facing the complex environment of distribution network construction and renovation projects, it is necessary to construct a comprehensive, systematic and accurate technical and economic evaluation system for distribution network construction and renovation projects. This paper first constructs a unified evaluation model based on technical and financial evaluation, taking account of economic and social benefits; then implements different evaluation index systems by cluster analysis; finally carries out an example measurement based on five distribution network projects. The research results can be widely used in investment decision, process control and post-evaluation of distribution network construction and renovation projects, which is conducive to the investment control of this projects for power grid companies.
