Cyber-Physical Security in Power Electronic Systems

Abstract

The integration of power electronic systems into the infrastructure of modern power grids has revolutionized the control, efficiency, and flexibility of energy distribution. However, this amalgamation of physical components with interconnected digital networks has introduced a complex interdependency known as cyber-physical systems (CPS). This integration poses significant challenges regarding cybersecurity, as it exposes these systems to a myriad of vulnerabilities stemming from the convergence of physical hardware and cyber components. This research article navigates through the intricate landscape of cyberphysical security within power electronic systems, delineating the vulnerabilities, threats, and proactive mitigation strategies necessary to fortify critical power infrastructure against potential cyber intrusions. It explores vulnerabilities in hardware, software, supply chains, and human factors, highlighting the multifaceted nature of risks within power grids. Delving into potential threat scenarios encompassing ransomware attacks, supply chain compromises, and sophisticated social engineering tactics, this article provides a comprehensive overview of the evolving threat landscape confronting power grids. Furthermore, it presents
a spectrum of mitigation strategies encompassing secure hardware design, robust software security measures, access controls, and collaborative efforts to fortify supply chains and regulatory compliance. Looking towards the future, the article outlines potential research directions, including the integration of artificial intelligence, quantumsafe cryptography, and dynamic risk assessment models to adaptively enhance cybersecurity strategies. Emphasizing the importance of collaboration, continual improvement, and a proactive stance, this research aims to contribute to fortifying critical infrastructure against the persistent and evolving challenges posed by cyber threats in the realm of power electronic systems.
