A survey of communication technologies for smart grid connectivity

The traditional electric power system is examining a transformation process to an intelligent, efficient, and cost-effective smart grid (SG) system. The SG has different subsystems for its accurate functionality. Among these subsystems, the communication subsystem plays a vital role for real-time data sharing between devices and systems connected in SG domain. In this paper, a survey of smart communication subsystem is provided and several communication technologies that have strong potential for implementation in future SG applications by electric utility companies are discussed. The advantages and disadvantages of each communication technology in the SG domain are also presented. Finally, a hybrid communication model is suggested for reliable communication between smart meters and control system in the SG.
