A level-1 probabilistic risk assessment to blackout hazard in transmission power systems
Power system reliability Power system security Power system stability Probabilistic risk analysis Blackout Monte Carlo methods
2012/4/15
The blackout risk in power systems is difficult to estimate by actual probabilistic methods because they usually neglect, or do not properly consider, the dependencies between failures and the dynamic...
A probabilistic performance-based risk assessment approach for seismic pounding with efficient application to linear systems
Non-stationary random processes Separation distance Seismic pounding Non-classically damped systems Performance-based earthquake engineering
2012/4/26
Earthquake ground motion excitation can induce pounding in adjacent buildings with inadequate separation distance. The corresponding risk is particularly relevant in densely inhabited metropolitan are...
