Research on Application Level of Big Data and Cloud Computing Information Technologies in Smart Grid

Abstract

With the rapid development, smart grid and information technologies have been integrated so tightly that it is imperative to evaluate the application level of advanced information technologies for the informatization in smart grid. In this article, from two aspects (cloud computing and big data), an evaluation index system with 15 indexes has been established to evaluate the application level of advanced technologies in smart grid information system. An evaluation model has been built by combining order relation weight method and matter-element extenics. Finally, this evaluation model has been validated via a case of provincial power grid in China, which shows that the evaluation result on application level of advanced technologies could help very well to make decisions, and be theoretically and practically significant for the informatization in smart grid.
