Smart Grid

Testing the Fault Tolerance of a Backup Protection System Using SPIN

Abstract: 

This article advocates the use of automated model checking to find vulnerabilities in cyber-physical systems. Cyber-physical systems are increasingly prevalent in daily life. Smart grids, in particular, are becoming more interconnected and autonomously run. While there are advantages to the evolving critical infrastructure, new challenges arise in designing fault-toler-ant cyber-physical systems. Tools for automated model checking are a key asset in designing and evaluating cyber-physical systems and their components to maximize robustness and to pinpoint vulnerabilities so that they can be mitigated as early in the design process as possible. As a proof of concept for this model checking concept, this paper tests the fault tolerance of a Wide-Area Backup Protection System (WABPS). Each line in the WABPS incorporates a pair of autonomous agents, hosted on intelligent electronic devices (IEDs), which monitor the status of the line and make decisions regarding the safety of the grid.
