Abstract:

The Smart Grid is a cyber-physical system comprised of physical components, such as transmission lines and generators, and a ; network of embedded systems deployed for their cyber control. Our objective is to qualitatively and quantitatively analyze the ; reliability of this cyber-physical system. The original contribution of the approach lies in the scope of failures analyzed, which crosses ; the cyber-physical boundary by investigating physical manifestations of failures in cyber control. As an example of power electronics ; deployed to enhance and control the operation of the grid, we study Flexible AC Transmission System (FACTS) devices, which are ; used to alter the ﬂow of power on speciﬁc transmission lines. Through prudent fault injection, we enumerate the failure modes of ; FACTS devices, as triggered by their embedded software, and evaluate their eﬀect on the reliability of the device and the reliability of ; the power grid on which they are deployed. The IEEE118 bus system is used as our case study, where the physical infrastructure is ; supplemented with seven FACTS devices to prevent the occurrence of four previously documented potential cascading failures.
