A cyber-physical power system test bed for intrusion detection systems

The rapid advancement of technology used in operation, monitoring, and control introduces several threats against power system. Cyber-physical power system vulnerabilities are increasing and the consequences of attack can be catastrophic. Understanding power system phenomena and attacks is vital to identifying and detecting such events. Researchers require a suitable power system test bed that can provide a platform for simulation of power system events and attacks. An essential part of such a test bed is the ability to provide software and hardware interaction to mimic real world scenarios. This paper presents a test bed for the development of an intrusion detection system (IDS) for power systems. The test bed consists of a power system modeled on a real time digital simulator (RTDS), a data collection and processing engine, and a MATLAB/RSCAD parameter calculation engine. This test bed provides a platform for hardware in the loop (HIL) simulation, power system attacks, and generates data sets required by cyber security researchers. Coordinated distance protection and overcurrent protection schemes are implemented on the IEEE 9 bus system and a 3-generator 4 bus system [11]. Fault, contingency and cyber-attack scenarios have been developed for both power systems. Selected relevant simulation results are presented.
