# Cascading Network Failure in Power Grid Blackouts

@inproceedings{Dobson2015CascadingNF, title={Cascading Network Failure in Power Grid Blackouts}, author={Ian Dobson}, booktitle={Encyclopedia of Systems and Control}, year={2015} }

Cascading failure consists of complicated se- quences of dependent failures and can cause large blackouts. The emerging risk analysis, simula- tion, and modeling of cascading blackouts are briefly surveyed, and key references are sug- gested.

The cascade simulations demonstrate that the assumptions underlying the DC model (e.g., ignoring power losses, reactive power flows, and voltage magnitude variations) can lead to inaccurate and overly optimistic cascade predictions.

This work provides the first methods for protecting the grid against potential line failures caused by MAD attacks, and demonstrates that practical upper and lower bounds on the maximum $\alpha$ for which the grid is $\alpha D$-robust can be found efficiently in polynomial time.

Protecting the Grid Against MAD Attacks

- Computer ScienceIEEE Transactions on Network Science and Engineering
- 2020

This paper develops two algorithms named SAFE and IMMUNE for finding efficient operating points for generators during the normal operation of the grid such that no lines are overloaded instantly after any potential MAD attacks, and develops efficient methods to verify in advance if such overloads can quickly be cleared by changing the operating points of the generators after any attacks.

Comparing the Effects of Failures in Power Grids Under the AC and DC Power Flow Models

- EngineeringIEEE Transactions on Network Science and Engineering
- 2018

It is demonstrated that the effects of a single line failure on the distribution of the flows on other lines are similar under the AC and DC models, however, the cascade simulations demonstrate that the assumptions underlying the DC model can lead to inaccurate and overly optimistic cascade predictions.
