Cybersecurity in microgrids: A review on advanced techniques and practical implementation of resilient energy systems

Abstract

Recent progress in microgrids (MGs) has resulted in increased acceptance and utilization of green energy sources, energy storage technologies, and MGs. This has facilitated a more effective and practical administration of distributed energy resources (DERs). The progress in MGs, along with the implementation of hierarchical supervision and monitoring, has facilitated the transmission of information within contemporary communication systems. The incorporation of cyber physical systems (CPS) within MGs has heightened their susceptibility to cyber-attacks, thereby converting them into cyber–physical systems. Thus, emphasizing the importance of preventing, detecting, and isolating cyber-attacks is essential for the effective management of MG. This study offers an in-depth examination of cyber security within the energy sector, exploring the historical backdrop of cyber-attacks and classifying different forms of MG breaches, encompassing both cyber and physical security strategies. This study explore into the intricate communication networking infrastructure susceptible to attacks, particularly emphasizing data centers, and underscores the critical role of MG management in alleviating cyber risks. The study presents a framework that strategically improves cyber security defenses through a classification of countermeasures. The work offers significant perspectives on present and forthcoming advancements, promoting a forward-thinking strategy for safeguarding essential infrastructure in a world that is becoming more digitized.
