Convergence of sensor networks/internet of things and Power Grid Information Network at aggregation layer

The Sensor Networks and “Internet of Things” (IOT for short) have been regarded as the trend of information technology. At the same time, Intelligent Power Grid is also becoming the key part of national energy program. As the collection of power engineering and ICT, the key technologies of IOT and ICT applied in Power Grid System are being highly concerned with manufacturers and government. In this paper, the natural bottleneck between mass sensor information and Electric Power Communication Transmission Network is proposed and put forward the concept of information aggregation layer under the background of heterogeneous network convergence. Power Grid Information Network and Sensor information processing and data fusion in Aggregation Layer will be taken on the embedded smart gateway and provide front-end processing and analysis of sensor information, which can be used to implement in varied Intelligent Power Grids scenario with a unified data-aware, access, transmission and data fusion. At the end, the article describes a number of Intelligent Power Grids application of innovation based on the aggregation layer embedded smart gateway device and looking forward to a vision of fully perception and integrated next-generation Power Grids.
