The Comprehensive Evaluation of Smart Distribution Grid Based on Cloud Model

Smart distribution grid is an important part of smart grid. Cloud model is used in smart distribution grid; It can achieve mutual combination and conversion between the qualitative evaluation system and the quantitative study. The paper introduces the development status of the smart distribution grid and distribution grid, the numerical characteristics of cloud model and algorithm of synthesized cloud. By establishing the model of two-level index synthesized cloud and remarks cloud, the evaluation results can be given in the form of probability distribution. The example shows that the model of the evaluation results is intuitive and reliable; it has important significance in guiding practice. (C) 2012 Published by Elsevier Ltd.
