Research on applications of the internet of things in the smart grid

The internet of things(IoT) technology has great potential in obtaining, analyzing, processing, controlling and feeding back the information of entity properties (location, status, behavior, characteristic, etc.), which will play an active role in promoting the development of smart grid. In this paper, we apply the IoT technology in the smart grid field. A kind of system architecture of smart grid is built according to the IoT system architecture. The system architecture of smart grid is divided into three layers-the perception layer, the communication layer and the application layer. The application of IoT technology in every layer of the system architecture of the smart grid is analyzed and discussed in detail. Finally, the application prospect and problems which should be solved are forecast. It is found that the IoT technology will make smart grid more efficient, more intelligent, more secure and more convenient.
