Abstract

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, we have developed city grid online risk assessment software, and have provided a clear description of some key technologies of implementation and calculation process after installation. Finally, the test result shows the functionality and applicability of our software.
