Cyber Security Use Case on a Smart Power Distribution System - Physical Subsystem

A Cyber-physical system (CPS) was simulated for peak shaving application to investigate vulnerabilities and re-silience of a power distribution system. The power system was implemented in the Real Time Digital Simulator (RTDS), including a remote terminal unit (RTU), a distribution transformer, and four Distributed Energy Resources (DERs). The communication system was implemented in Common Open Research Emulator (CORE). The cyber-attacks, Denial of Service (DoS) and Man-in-the-Middle (MITM), were simulated by attacking the communication between the Aggregator and DERs. Comparative analysis between normal system operation and post-attack operation revealed significant impacts. Cyber-physical system simulation provides valuable insights for researchers in developing detection and mitigation methods.
