Information security risk assessment of IEC 61850-based power control systems is currently an unsolved problem. One of the reasons is a lack of methodology for asset analysis, which is an important process of risk assessment. As the features of IEC 61850-based power control systems are different from general IT systems, a specific methodology of asset analysis is introduced. Based on the requirements...
With the rapid development of urbanization, the importance of city power grids safety has been gradually recognized. Given a full consideration for the characteristics of city power grids, we design a complete set of risk evaluation index system based on probability theory by employing risk theory and analytic hierarchy process (AHP) in power system online static security risk assessment. Further,...
Information security risk assessment combined with power control process is an issue which has not properly solved yet. As substation automation system (SAS) functions as the key link of between implementation of control instructions and the collection of operation information, research on the application of information assets identification method in SAS under network environment, is an important...
