The network diagram shown here was created by the SG Networks Task Force
within the Open SG Users Group as discussed in
Smart Grid Communications Network Planning
Services. The Smart Grid Planning Tool reflects the structure of a
centralized Distribution Operations function as the heart of the Smart Grid
Network. Communications with customer premises takes place primarily through an
Advanced Metering Infrastructure (AMI) network subset. Communicatinos with
distributed field devices such as reclosers, switches and capacitor banks takes
place through a Field Area Network (FAN). Communications with substations relies
on the traditional Supervisory, Control and Data Acquisition (SCADA) network
subset.

Custom Tool Development For Special Applications |
|
|
|
|
The modeling to date has not focused heavily on the independent system operator
(ISO) or the Regional Transmission Organization, or bulk generation aspects of
the Smart Grid. For those organizations, additional use cases need to be
identified, and added to the tool. Consequently, a custom version for such
organizations is offered by Aurastar, since the principal of Aurastar developed
the original planning tool. |

Spectrum Management |

One area where substantial progress has been made, lies in efforts to build the
case for dedicated spectrum allocations for the Smart Grid. Today, these
allocations do not exist, and the focus tends to be on unlicensed bands, with
all of their negatives, or Auctioned Spectrum.
The following screen depicts the analysis of States, Counties and Census Tracts
to be included in a spectrum study where the query depicted in Smart Grid
Feasibility Studies can be scaled by local populations in order to generate
anticipated traffic levels. These can then be translated into spectrum
requirements to serve particular areas.
