Data collecting and processing method in distribution system using edge computing technology

Abstract

With the improvement of automation system and the proliferation of Internet of Things (IoT) in the distribution system (DS), massive heterogeneous data generated at the edge of DS is utilized for various applications. Edge computing can be a good solution to manage those data while guarantee diverse performance requirements, especially limited latency. In this paper, we propose a cloud-edge architecture for DS, and specifically illustrate the logic design of the edge computing (EC) device for DS (DSEC). In order to manage data at the edge of DS, a DSEC-based data collecting method, including a protocol identification and conversion method, a naming method and a data management method, is proposed. Lastly, a DSEC-based data processing method considering local processing and cloud offloading is designed to improve the utilization of cloud & edge resources. The proposed methods can ensure rapid data analysis requirements and better data service in DS.
