Abstract
With the fast development of Smart Grid globally, the security issues arise sharply and Non-Technical Loss (NTL) fraud is one of the major security issues. There are some existing NTL fraud detectors, however, when big data security challenges emerge in Smart Grid, none of them can detect NTL fraud for big data in Smart Grid. In this paper, we propose ENFD, an NTL detection scheme enabled by Edge Computing and big data analytic tools to address big data NTL fraud detection problem in Smart Grid. The research work provides us with experience of developing big data security solutions in Smart Grid. The experimental results show that ENFD can efficiently detect big data NTL frauds which cannot be detected by the state-of-the-art detectors. ENFD can detect small data NTL frauds as well and the average detection speed is about six to seven times that of the fastest detector exists in the literature.
