Resilience Enhancement Techniques in Cyber Physical Distribution System: an Overview

The evolution of power systems into cyberphysical distribution systems (CPDSs) integrates complex communication networks with traditional power infrastructures, thereby exposing systems to both cyber and physical disruptive events. This paper investigates resilience enhancement strategies designed for CPDS, focusing on countermeasures against natural hazards, malicious attacks, technical failures within communication networks, and interdependent cyber-physical failures. First, we present the structure of CPDS and define resilience within this context and differentiate it with the definition of reliability and cybersecurity. Subsequently, we categorize failures into four types of disruptive events and evaluate the state-of-the-art resilience enhancement strategies, respectively. Finally, we highlight key research gaps and propose future directions to enhance the resilience of CPDS.
