Smart Cities espouse an innovative framework for urban development that promotes sustainable revival and is predominately concerned with the integration of ICT with established protocols and standards. Revitalized Smart Grids (SGs) can integrate non-renewable and renewable power sources, reducing environmental risks and optimizing operational costs. Avant-garde management frameworks and applications that aim to aggrandize system efficiency, dependability, durability, and interoperability. The integration of SGs with cyber-physical systems (CPSs) in power systems vociferates for specific control and cybersecurity measures. However, the risk of cyber-physical attacks (CPA) has grown increasingly nonfictional for such ICT-enabled systems. This requires systematic research into the sophisticated interrelatedness between physical and cyber systems in examining and fixing the challenges in SG-CPS. Researchers evaluated potentially debilitating and significant risks and CPA, speeding up the deployment of new solutions and strengthening SG-CPS. This study explores security measures, emphasizing interaction modeling and countermeasures for SG-CPS.
