“…In normal operation, with the proper setting configuration of the five relays in either low-or high-loading conditions, physical faults will lead to normal protection system operation. When a fault occurs on a transmission line, the feeder relays R11, R12, and R13 trip, open the breakers, and send a GOOSE block to the generators' relays R6 and R18 to prevent a false operation in the unlikely event that one of them is detected as a second stage I >> [37]. However, we assumed low loading conditions such that G3 is out of service and only G1 supplies the total power to the loads L1, L2, and L3.…”

With the deployment of numerous innovative smart grid technologies in modern power systems, more real-time communication and control are required due to the complexity and proliferation of grid-connected systems, making a power system a typical cyber-physical system (CPS). However, these systems are also exposed to new cyber vulnerabilities. Therefore, understanding the intricate interplay between the cyber and physical domains and the potential effects on the power system of successful attacks is essential. For cybersecurity experimentation and impact analysis, developing a comprehensive testbed is needed. This paper presents a state-of-the-art Hybrid Physical Co-simulation SG testbed at FIU developed for in-depth studies on the impact of communication system latency and failures, physical events, and cyber-attacks on the grid. The Hybrid SGTB is designed to take full advantage of the benefits of both co-simulation-based and physical-based testbeds. Based on this testbed, various attack strategies are tested, including man-in-the-middle (MitM), denial-of-service (DoS), data manipulation (DM), and setting tampering (change) on various power system topologies to analyze their impacts on grid stability, power flow, and protection reliability. Our research, which is based on extensive testing on several testbeds, shows that using hybrid testbeds is justified as both practical and effective.
