IoT Integration for Smart Grid Efficiency

The evolution of smart grids is closely tied to the advancements in Internet of Things (IoT) technologies, enabling real-time monitoring, two-way communication, intelligent control, and integration of renewable energy sources. This paper presents a structured review of recent literature highlighting the role of IoT in enhancing smart grid performance with respect to energy efficiency, security, and data-driven automation. Despite notable progress, challenges such as data interoperability, cybersecurity, and system scalability remain critical. To address these issues, a comprehensive IoT-Driven Smart Grid Efficiency Framework (ISGEF) is proposed, comprising four layers—perception, network, data processing, and application. This layered architecture supports modularity, real-time decision-making, secure communication, and effective energy management. The proposed framework is designed to facilitate seamless integration across residential, industrial, and distributed generation scenarios, while promoting sustainability and resilience. Implementation strategies, technological choices, and potential benefits are discussed to support future smart grid development and research directions.
