Probability of failure of overloaded lines in cascading failures
Blackouts in transmission power systems are due to cascading failures. Outages of overloaded lines are main contributors to cascading failures. The probability of line tripping as a function of the overload must be modeled. Previous models do not rely on empirical evidence or detailed analysis. This paper proposes a simple model backed up by a detailed analysis.
