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

• 2017
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.

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.

• Computer Science
• 2019
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
• Computer Science
IEEE 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
• Engineering
IEEE 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.
