Research on information security strategy and risk management for smart grid

Firstly, analyzes the characteristics of the smart grid network, this paper expounds the importance of information network security in the safe operation of smart grid. Based on the analysis of power information security protection framework, pointing out the importance of establishing the information safety monitoring system for smart grid. Secondly, according to the mainfunctions and characteristics of the smart grid information new elements are analyzed. Various risks as well as malicious attack scenarios to the intelligent power network are analyzed from the aspect of information security, ranging from the information collection, transmission, management and interaction. Finally, some feasible countermeasures and the improvement measures based on modern power system developments are given to enhance the information security of the intelligent power system in key technologies, standards, and policies.
