Security Assessment and Impact Analysis of Cyberattacks in Integrated T&D Power Systems
This work addresses the critical problem of cybersecurity vulnerabilities in integrated T&D power systems for grid operators and energy providers, providing an incremental assessment of potential attack impacts.
This paper assesses the impact of cyberattacks on an integrated transmission and distribution (T&D) power grid model with distributed energy resources. It identifies critical assets and analyzes risks using the OCTAVE Allegro methodology, focusing on data integrity attacks in solar PV controllers, control signal blocking in protective switches, and coordinated monitoring/switching time-delay attacks.
In this paper, we examine the impact of cyberattacks in an integrated transmission and distribution (T&D) power grid model with distributed energy resource (DER) integration. We adopt the OCTAVE Allegro methodology to identify critical system assets, enumerate potential threats, analyze, and prioritize risks for threat scenarios. Based on the analysis, attack strategies and exploitation scenarios are identified which could lead to system compromise. Specifically, we investigate the impact of data integrity attacks in inverted-based solar PV controllers, control signal blocking attacks in protective switches and breakers, and coordinated monitoring and switching time-delay attacks.
