The Role of Power Line Communications in the Smart Grid Revisited: Applications, Challenges, and Research Initiatives

Abstract

Power line communications (PLC) have been an active research area for many years and it is still the case, mainly because they present economic and technical natural advantages for a wide range of applications using the existing electrical grid as transmission medium. In this paper, the authors provide an update on PLC technologies and their applications in Smart Grids, the main challenges they are currently facing, how they can be addressed, and the current research initiatives.
