Real-Time Simulation of a Cyber-Attack Scenario on a Power Distribution Substation

This paper will describe the real-time simulation of a virtual Denial-of-Service cyber-attack scenario to a power distribution system software model on OPAL-RT. This includes the evaluation of the system response to major power instabilities during the attack. Using the Modbus TCP communication protocol, a SCADA interface communicates and interacts with the real-time simulation power distribution system model in OPAL-RT. With this methodology, different cyber-attacks on a virtual system can be evaluated and verified with no threat to the physical system.
