Benefit Evaluation of Power Grid Project Based on Gray Triangle Whiten Weight Function Model

With the rapid development of the smart grid in China, it is becoming more and more important to make a scientific and rational benefit evaluation of the power grid project. In this paper, a comprehensive evaluation index system of general power grid projects is established. Based on the grey triangle whiten weight function theory and the variation coefficient method, a benefit evaluation model is established, and an empirical analysis of the project of a certain city power grid is carried out. The results show that the model has a strong practical value and provides ideas and methods for the benefit evaluation of related power grid projects.
