Spatial correlation analysis of cascading failures: Congestions and Blackouts
Cascading failures have become major threats to network robustness due to their potential catastrophic consequences, where local perturbations can induce global propagation of failures. Unlike failures spreading via direct contacts due to structural interdependencies, overload failures usually propagate through collective interactions among system components. Despite the critical need in develo...
متن کاملRisk analysis of critical loading and blackouts with cascading events
We analyze a 15-year time series of North American electric power transmission system blackouts for evidence of self-organized criticality. The probability distribution functions of various measures of blackout size have a power tail and R/S analysis of the time series shows moderate long time correlations. Moreover, the same analysis applied to a time series from a sandpile model known to be s...
متن کاملCascading Failures: Extreme Properties of Large Blackouts in the Electric Grid
Introduction On August 14, 2003, at 1:42pm a power grid operator at the US Midwest Independent System Operator remarked, casually, to an operator at Louisville Gas and Electric, “Hey, what is going on man?” [1] Two and a half hours later, 50 million people across the Northeastern US and Southeastern Canada had lost access to power from the electric grid (see Figure 1). Three years later, on Nov...
متن کاملAnalysis of Cascading Failures in Power Networks
This thesis studies the characteristics of cascading failures in a simulated linear swingequation model for simple power networks. The model transitions from displaying only small average failure size to undergoing large average failure size as the loading of the system is increased. For some parameter values, the transition region becomes critical, and it exhibits failures of all sizes whose d...
متن کاملCascading Network Failure in Power Grid Blackouts
Cascading failure consists of complicated sequences of dependent failures and can cause large blackouts. The emerging risk analysis, simulation, and modeling of cascading blackouts are briefly surveyed, and key references are suggested.
