Comprehensive Evaluation Of Smart Grid Based On Combined Evaluation Theory

Smart Grid is a complicate and enormous systematic project. The comprehensive and scientific evaluation of smart grid can help to find the weakness and restrictions and achieve the balance development of technology and economy. The evaluation work has the significant meanings of guiding the smart grid plan, construction, operation, and management.In this paper, the smart grid comprehensive evaluation system is in depth studied. Based on the smart grid development situations and features in China, the content, features and targets of smart gird in china were researched. The smart grid comprehensive evaluation index system is constructed from the safe and reliable, econmic, environmental friendly, interactive and efficient. The existing comprehensive evaluation methods were compared. This paper put forward the comprehensive evaluation of smart grid based on combined evaluation theory, with the combination of ANP and Entropy to be the method of weights determing. According to the content and the characteristics of indexes, the evalution mode combined the entropy method, ANP, TOPSIS, gray correlation method, data envelopment analysis and linear weighted method to be the comprehensive evaluation mode of smart grid based on combined evaluation theory, which may achieve the scientific, rational, comprehensive, effective and comprehensive evaluation of Smart Grid.The test results of classical examples show that this method can provide useful reference for smart grid plan adjustment and improvement, smart gird technical route and key fields establishment and the implement effect summarizing. It is the important support and theory basis for the strong smart grid scientific development.
