Smart Grid Communication Network Technologies

Here is a literature review provided by EnergyStrain.com on Smart Grid Communication Networks. 

Selected Review of Literature: Smart Grid Communication Network

Given the increased emphasis on energy efficiency, the current electrical grid is in need of a robust communication network.  The communication infrastructure will rely on three technologies: 
to reliably transmit low latency data at speeds of 2-to-5 Mbps per device (Sood, Fischer, Eklund, & Brown, 2009).

The smart grid will need to be able to handle two-way communication in order to share energy-related data amongst utilities and end-users (Aggarwal, Kunta, & Verma, 2010).

This communication system must handle large amounts of continual two-way data transmission from all electricity users, devices, and sensors in order to provide proper usage feedback to both the end-user and to the utility (Aggarwal, et al., 2010).

Due to the high cost of implementing a smart grid communication network it must be built with adequate capacity for future growth.  Utilities will need to plan their systems for increased usage during emergency situations, and for a lifespan of roughly 20 years (Wenpeng, Sharp, & Lancashire, 2010).  It is unlikely that any one-communication technology will reign supreme.  It is much more likely that we will see hybrid systems that implement several or all of these technologies for varying circumstances (Tsiropoulos, et al, 2009).
