Through smart gateways, devices with different protocols can achieve seamless integration and communication, simplifying the development work of engineers, improving interoperability between devices, achieving unified monitoring and control, and improving production efficiency. The electrical distribution landscape is rapidly evolving with the integration of smart technologies, transforming traditional distribution boxes into intelligent, connected devices. It has good adaptability and scalability and is widely used in industrial automation. It is an important part of PLC (Programmable Logic Controller). The component is responsible for. Today, smart grid solutions or IoT solution and Services for grid infrastructure is playing a major role in developing many use-case based energy conservation solutions, by connecting disparate platforms in home automation, building & infrastructure automation, and transmission & distribution. Digital technologies such as Cloud Computing, Big Data, Internet of Things (IoT), Artificial Intelligence (AI) and Industry 4. 0 are phenomenon which are changing the world we are living in. As utilities and governments prioritize modernizing distribution networks, the rapid evolution. Smart grids (SGs), as an emerging grid modernization concept, is spreading across diverse research areas for revolutionizing power systems.
