Understanding how cyber faults affect power system protection devices is critical for grid security. Existing approaches often separate physical and cyber analysis. This work is innovative because it integrates behavioral models of protection devices with cyber fault scenarios to study coupled effects on cascade progression.
This paper develops a simulation testbed for analyzing cascading failures in power systems, using behavioral models of protection devices including distance relays, overcurrent relays, and circuit breakers. The work incorporates cyber faults and studies their impact on cascading failure progression. The methodology enables contingency analysis with cyber fault injection.
The paper demonstrates how cyber faults in protection assemblies (such as stuck open faults and spurious detection faults) can initiate or accelerate cascading failures in power grids. Results validate the testbed against IEEE 14-bus system behavior and identify critical cyber-physical failure combinations.

abstract = {Electrical power systems are heavily instrumented with protection assemblies (relays and breakers) that detect anomalies and arrest failure propagation. However, failures in these discrete protection devices could have inadvertent consequences, including cascading failures resulting in blackouts. This paper aims to model the behavior of these discrete protection devices in nominal and faulty conditions and apply it towards simulation and contingency analysis of cascading failures in power transmission systems. The behavior under fault conditions are used to identify and explain conditions for blackout evolution which are not otherwise obvious. The results are demonstrated using a standard IEEE-14 Bus System.},
