Application of edge-cloud collaborative intelligence technologies in power grids

With the continuous development of the Internet of things on electricity (IoTE) and large-scale deployment of intelligent edge devices, an explosively increasing amount of data are being generated at the network edge. The efficient, fast and secure processing and analysis of the massive edge located data brings great challenges for the traditional cloud computing-based intelligence technologies. Instead, edge-cloud collaborative intelligence (ECCI) technologies can significantly outperform the cloud computing-based intelligence in terms of the network bandwidth saving, delay reduction and privacy protection, and therefore have shown a great potential in boosting the development of power grids. To investigate the application of ECCI in power grids, the concept and research progress of ECCI were firstly introduced. The characteristics and advantages of ECCI were summarized and its applicability in the power grids were discussed. Secondly, the key technologies of ECCI applications for power grids were discussed and the solutions based on ECCI technologies for two typical scenes were proposed respectively. Finally, a brief discussion of future work was given.
