The smart grid allows consumers and utility grids to communicate, allowing for the most efficient use of generated energy based on environmental, price, and system technical factors. One of the primary advantages of this system is energy management, which is carried out in conjunction with the internet of things (IoT), with real-time monitoring of devices and control data processing. The purpose of the Internet of Things in this project is to build a smart control system to manage generated electricity among several Nano grids by remotely monitoring generated and used power. A set of multifunction sensors is used to wirelessly sense real-time data and convert it into the necessary format, as well as to help move the sensed data over the network cloud via the 'Internet Connection'. Several slave nodes are present in a microgrid (SN). Every SN serves as its own grid (Nano grid), with two or three independent renewable energy sources connected to the master node of the central control unit (MN). To assure a satisfactory outcome, a prototype was built using solar cells and wind turbines as power sources, with an ARDUINO microcontroller managing and controlling power transfer between slave nodes. The practical results showed a good match between the simulated and practical results.
