Application of wireless communication technologies in Smart Grid

Abstract

Dileep

The Smart Grid is an advanced digital two-way power
flow power system capable of self-healing, adaptive, resilient
and sustainable with foresight for prediction under
different uncertainties. Smart grid technology places
greater demands for reliability on communications
infrastructure. Due to the large number of distribution
components connected to the distribution level feeders,
a massively deployed wireless communication network is
identified as the potential technology for this application.
This paper presents a comprehensive review of wireless
communications technologies for implementation of
smart grid in a systematic way, a case study of Puducherry
Smart Grid pilot project is also presented. Various network
attributes like internet protocol (IP) support, power
usage, data rate etc. are considered to compare the
communications technologies in smart grid context.
Techniques suitable for home area networks (HANs) like
ZigBee, Bluetooth, Wi-Fi, and Z-Wave are discussed and
compared in context of consumer concerns and network
attributes. A similar approach in context of utilities concerns
is adopted for wireless communications techniques
for neighborhood area networks (NANs) which include
WiMAX and GSM based cellular standards. Smart grid
applications, associated network issues and challenges are
elaborated at the end.
