A review of security in electrical power information system

In order to provide a reference for the establishment of power information system, this paper reviewed electrical power information system including security model, communication mechanism and risk assessment. Security model including OSI and P2DR, communication mechanism including IEC 62351 and IEC 61850, risk assessment including Fault Tree and Attack Tree were introduced. In each section, literature of related work are presented to strengthen the background of the research, and the drawbacks of each model are also mentioned. In addition, this paper proposed requirements of the power information system design, that information security is a moment of change in the process. the design needs to grasp this feature.
