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. 
Analyzing Cascading Failures in Power Grids under the AC and DC Power Flow Models
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.
A network approach for power grid robustness against cascading failures
Careful assessment of the design and expansion choices of grid topologies incorporating the insights provided by this paper optimizes the robustness of a power grid, while avoiding the Braess's paradox in the system.
Stigmergy-based Load Scheduling in a Demand Side Management Context
This work proposes an approach, based on a fundamental coordination mechanism from nature, namely stigmergy, which could be influenced to match the RES supply, such that the balance in the power grid can be maintained by increasing RES utilization.

A Learning-Based Method for Generating Synthetic Power Grids
This work thoroughly study the structural properties of the U.S. Western Interconnection grid (WI) and presents the network imitating method based on learning (NIMBLE) for generating synthetic spatially embedded networks with similar properties to a given grid.
Aggregated Demand Increase Line Overload Transmission Network Distribution Network Remotely Turning ON / OFF Devices Automatic Generation Increase
The novel notion of αD-robustness for a grid indicating that line overloads can either be prevented or cleared after any attacks based on the two forms of introduced defenses if an adversary can increase/decrease the demands by at most α fraction is defined.
Robustness of complex networks: Theory and application
This work studies how to add a single link into an existing network such that the robustness of the network is maximally improved among all the possibilities, and proposes strategies that take into account the structural and spectral properties of networks.
Protecting the Grid against IoT Botnets of High-Wattage Devices
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
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
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.

Large blackouts are typically caused by cascading failure propagating through a power system by means of a variety of processes. Because of the wide range of time scales, multiple interacting

An advanced tool for analyzing multiple cascading failures
This paper summarizes the Southern Company methodology and experience in advanced analysis of cascading failures. Cascading failures occur due to loss of generating units at a station, breaker
A probabilistic model for the dynamics of cascading failures and blackouts in power grids
Current power grids suffer periodic disturbances that may trigger cascades of component failures, which, in turn, can result in blackouts of different scales. Understanding cascading failures and the
We propose an analytically tractable model of loading-dependent cascading failure that captures some of the salient features of large blackouts of electric power transmission systems. This leads to a
Exploring Complex Systems Aspects of Blackout Risk and Mitigation
While the absolute frequency of blackouts of all sizes may be reduced, the underlying forces can still cause the relative frequency of large blackouts to smallblackouts to remain the same, and in some cases, efforts to mitigate small blackouts can even increase the frequency ofLarge blackouts.

Standard transmission line outage historical data is used to obtain the network topology in such a way that cascades of line outages can be easily located on the network and statistics quantifying how cascading outages typically spread are obtained.
Complex systems analysis of series of blackouts: cascading failure, critical points, and self-organization.
An overview of a complex systems approach to large blackouts of electric power transmission systems caused by cascading failure is given and it is suggested that power system operating margins evolve slowly to near a critical point and confirmed using a power system model.
Long-Term Effect of the n-1 Criterion on Cascading Line Outages in an Evolving Power Transmission Grid
Cascading transmission line outages contribute to widespread blackouts. Engineers respond to the risk of cascading line outages by applying policies such as the n-1 criterion and upgrading lines
