Static Security Risk Assessment Based on Outage of Line

Abstract:

From the risk theoretical point of view, static security risk indicators of the transmission grid are built on the basis of the probability theory, grid static security risk indicators, including overload risk indicators and voltage-limit risk indicators. For both risk indicators, the probability of the outage of one line is considered, as well as in the case of the uncertainty of the power system the serious consequences caused by the outage of one line. And the overload risk assessment model and voltage-limit risk assessment model are built. Finally, quantitative assessment and calculation are done through the standard system examples of these two static safety risk indicators, then assess and sort the transmission lines of the importance based on the simulation results.
