Cyber Vulnerability Assessment of Microgrids with 5G-Enabled Distributed Control

Abstract

Enabling communication between the individual controllers of inverter-based resources (IBR) in a microgrid can result in improved system-wide response. However, it increases the vulnerability of microgrids to cyberattacks. This paper investigates the effects of cyberattacks on microgrids with 5G-enabled coordinated set point modulation (5GCSPM). A modified CIGRE North American MV distribution benchmark system with 28 IBRs equipped with 5GCSPM is built in PSCAD/EMTDC as the physical layer. A cyber-physical system is created by enabling TCP/IP communication between PSCAD/EMTDC and Raspberry Pi4. Different cyberattacks are carried out on the TCP/IP connection while running time-domain simulation studies to evaluate the performance of 5GCSPM.
