A survey on secure communication technologies for smart grid cyber physical system

Recent advancements in communication technologies and embedded system design have popularised the practical application of cyber–physical systems (CPS). A CPS combines physical components, computational elements, and communication networks. The smart grid CPS (SG-CPS) is an example of such a system, featuring physical devices with diverse communication needs and intermediary networks. Consequently, robust and secure communication networks are essential for optimal performance of the SG-CPS. This paper provides an overview of current technologies in SG-CPS, its implementation, benefits, and security issues. Our goal is to summarize the latest advancements, provide researchers with a comprehensive list of references, and encourage further exploration into this rapidly growing field. • Examination of SG-CPS architecture including communication model and technologies. • Analyzes various operational scenarios for smart grid communication systems • Identifies key challenges in smart grid communications and proposes potential solutions to address them. • Assesses the strengths, weaknesses, and solutions for diverse communication technologies applied to smart grid systems. • Explores potential research avenues for LTE and 5G-NR cellular networks in the context of smart grid communications.
