The Impact of the Locations of the DG Units on a Distribution Network during Cyberattacks

Abstract

Shifting towards renewable energy sources increases the cybersecurity challenges since various field devices are required to be utilized to ensure the high-performance operation of distributed energy resources (DER). The utilization of these different devices and algorithms makes DGs more vulnerable. In this study, we provide an assessment on the impact of the DG units’ locations in a distribution network during a cyber-attack targeting the pitch angle of a 660-kW turbine and the MPPT of a 0.5 MW PV system. This attack compromises 20% of the output of the DGs. The Wind turbine and the PV system were located in random locations in IEEE 33 bus test system. Three case studies were assessed based on root mean square error.
