Cascading blackout overall structure and some implications for sampling and mitigation
نویسندگان
چکیده
Cascading blackouts can be thought of as initiating events followed by propagating events that progressively weaken the power system. We briefly discuss the implications for assessing cascading risk by proper sampling from the various sources of uncertainty and for mitigating cascading risk by reducing both the initiating events and their propagation.

Complex Systems Analysis of Series of Blackouts: Cascading Failure, Criticality, and Self-organization
We give a comprehensive account of a complex systems approach to large blackouts caused by cascading failure. Instead of looking at the details of particular blackouts, we study the statistics, dynamics and risk of series of blackouts with approximate global models. North American blackout data suggests that the frequency of large blackouts is governed by a power law. This result is consistent ...

We give an overview of a complex systems approach to large blackouts of electric power transmission systems caused by cascading failure. Instead of looking at the details of particular blackouts, we study the statistics and dynamics of series of blackouts with approximate global models. Blackout data from several countries suggest that the frequency of large blackouts is governed by a power law...
متن کاملRisk Management of Cascading Failure in Composite Reliability of a Deregulated Power System with Microgrids
Due to power system deregulations, transmission expansion not keeping up with the load growth, and higher frequency of natural hazards resulting from climate change, major blackouts are becoming more frequent and are spreading over larger regions, entailing higher losses and costs to the economy and the society of many countries in the world. Large-scale blackouts typically result from cascadin...

Abstract: Blackouts are among the main threats to the security of electric power systems. Cascading failures are known as the most important agent for creating blackouts. Transmission lines are the basic equipment of power networks that their outage can make subsequent cascading outages. In this paper, based on the application of decision tree a new approach is proposed for online identificatio...
متن کاملAn Initial Complex Systems Analysis of the Risks of Blackouts in Power Transmission Systems
Electric power transmission systems are a key infrastructure and blackouts of these systems have major direct and indirect consequences on the economy and national security. In particular, electric power blackouts have cascading effects on other vital infrastructures. While it is useful to analyze the detailed causes of individual blackouts, in this paper we focus on the intrinsic dynamics of s...
