Cascading failures - Topological

Question 1

Detail the steps of the cascading failure model using the “Local
propagation of a fixed amount of load”. What type of results does
it provide? What kind of conclusions can be drawn from them?
What are the limitations of this model?

Question 2

Detail the steps of the cascading failure model using the “Flowbased
failure propagation”. What type of results does it provide?
What kind of conclusions can be drawn from them? What are the
limitations of this model?

Question 3

Given a real critical infrastructure, select an appropriate model for
the propagation of cascading outages in it and describe the
application of this model to the infrastructure.

Question 4

Define the concept of cascade-safe operations of network
systems. How can we use the results of cascading failure models
to identify cascade-safe operating margins? Detail the steps of
how you can compute these margins.

Question 5

Discuss strategies to prevent or mitigate the propagation of
cascading failures in single network systems. Provide a
realistic example and motivate your answer using the
results of the cascading failure models.

Question 6

What is the difference between “network static structure
analysis” and “Dynamic modeling of cascading failures
propagation in network systems”. What different types of
results are given by these two analyses?
