Cyber-physical cascading failure and resilience of power grid: A comprehensive review

Power grid defense against malicious cascading failure

An adversary looking to disrupt a power grid may look to target certain substations and sources of power generation to initiate a cascading failure that maximizes the number of customers without electricity. This is particularly an important concern when the enemy has the capability to launch cyber-attacks as practical concerns (i.e. avoiding disruption of service, presence of legacy systems, e...

Cascading 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.

Measures of Impact Under Cascading Failure of Power Grid

A centrality measure has been proposed considering the directionality of power flow of future smart grid. Applicability of the proposed method has been evaluated in several standard IEEE test systems. Various comparisons are shown between impacts of removal of critical nodes found from two different models: nondirectional and bidirectional. Larger impact of removing critical nodes found from bi...

On the Definition of Cyber-Physical Resilience in Power Systems

Modern society relies heavily upon complex and widespread electric grids. In recent years, advanced sensors, intelligent automation, communication networks, and information technologies (IT) have been integrated into the electric grid to enhance its performance and efficiency. Integrating these new technologies has resulted in more interconnections and interdependencies between the physical and...
