A new low‐cost and low‐power industrial internet of things infrastructure for effective integration of distributed and isolated systems with smart grids

Abstract Internet of Things (IoT) has recently become one the fast‐growing technologies in world. Integrating existing systems with smart grids still represents a significant challenge arising from massive cost upgrading infrastructure. This paper provides an IoT infrastructure solution based on newly designed low‐cost microcontroller‐based remote terminal unit (RTU) to integrate new, old, and conventional sites grids. The RTU supports Wi‐Fi communication includes digital/analog inputs outputs besides advantage serial data transmission standard RS‐485 as industrial field (IFC). Modbus protocol is utilized that can be interfaced over standard. having IFC integrated into enables link any supported device publish required cloud, ability add metering technologies, which allows Advanced Metering Infrastructure (AMI) these areas. IoT‐enabled Supervisory Control Data Acquisition (SCADA) system proposed for its advantages monitoring control. characterized by proper security low power consumption. simulated real application proof concept, results are discussed different case studies.
