Fuzzy Comprehensive Evaluation Algorithm for Power Information System Security Level Based on the Internet of Things

Abstract

With the development of information and communications technology, communication technology has been widely used in the electric power industry and has brought threats to the safe operation of power systems. Things can not only connect people; things can also connect other things. Therefore, the Internet of things plays an important role in power information system security. This study proposes a triangular fuzzy number weight method to calculate the index weight based on the analysis of the existing fuzzy algorithm and the security of a power information system. A fuzzy comprehensive evaluation model is established in accordance with matrix theory, statistical theory, and other methods after experimental data are analyzed. Results show that this algorithm can accurately evaluate system status and provide reference for managing power systems. The fuzzy algorithm for power information system security level ensures the safe operation of the power system and promotes its healthy development. This algorithm can significantly promote economic development in China.
