This paper investigates backbone communications in smart grid based on the application of wide area measurement system. The selection of communication protocols are most affected by the requirements of timing and load profile in the system, and this paper makes a comparison between different communication backbone mediums and propose an optimized protocol to achieve real-time data accessing and retrieving as well as preserving network security and data privacy. Extensive computer simulation has been implemented with Opnet to work out the traffic performance under varying load conditions.
