Background
•
NIST interoperability process identifies a number of high priority
issues including the role of IP and the use of wireless
communications:
– April 2009 workshop

hop1
– May 2009 workshop

•
NIST convenes an SDO workshop in August 2009 in order to
develop plans to address priority issues

Grid-Interop 2009
Issue: Role of Internet Protocol(s) in the Smart Grid
• The Smart Grid will use a variety of different networking
environments across different smart grid domains and
sub-domains
• Given its predominance and ubiquity, the Internet
technology (IP) is a key networking technology to
consider in the context of the Smart Grid
• A number of challenges remain to be addressed due to
the requirements imposed by many Smart Grid
environments and applications:
– What suite of IP protocols are applicable for specific Smart Grid
applications?
– What suite of IP protocols should be used for network control?
management? security?
– Are there any gaps with existing protocols?
– Should new protocols/extensions be developed?
Grid-Interop 2009
IP PAP#1: Guidelines for the use of IP protocol suite in the
Smart Grid
•
Develop Smart Grid application communication requirements
and devise a taxonomy for applications with similar network
requirements
– Draft matrix under development and available for review
http://collaborate.nist.gov/twikisggrid/pub/SmartGrid/PAP02Wireless/app_matrix_pap.xls
•
Identify a Core Protocol Suite for IP-based Smart Grid
– IETF drafts and reports submitted for considerations
http://collaborate.nist.gov/twiki-sggrid/bin/view/SmartGrid/PAP01InternetProfile
•
Develop Application-Specific Protocol Requirements
– Identify additional protocols or protocol enhancements beyond the core
suite required by a specific class of applications
– Develop guidelines for IP-based Smart Grid networks
•
Perform Gap Analysis
– Identify new protocol or protocol enhancement standardization
activities required to fully support the Smart Grid Vision

Issue: Use of Wireless Communications in the Smart Grid
• There are a number of advantages for using wireless
communications including:
–
–
–
–
–
Untethered access to information
Mobility
Interoperability
Reduced cost and complexity
Availability of technologies with different characteristics to choose
from
• A number of challenges remain to be addressed:
– How to choose among technologies with different characteristics?
– How do we know which technology to use for what Smart Grid
application?
– Are there any implications for using a certain wireless technology
in a certain environment?
– Are there any deployment? Interference issues?
Grid-Interop 2009
Wireless PAP#2 Guidelines for the use of wireless communications
in the Smart Grid
•
Develop Smart Grid application communication requirements and
devise a taxonomy for applications with similar network requirements
–
Draft under development and available for review
http://collaborate.nist.gov/twikisggrid/pub/SmartGrid/PAP02Wireless/app_matrix_pap.xls
•
•
Develop terminology and definitions
Create an attribute list and performance metrics for wireless standards
–
Draft developed and available for review
http://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP02Wireless/NIST_PAP2_Wireless_Characteristics-IEEE802-v_02.xls
•
Create an inventory of wireless technologies and standards that are
identified by each SDO
–
•
•
Feedback is expected by December 6, 2009.
Conduct an evaluation of the wireless technologies based on the
application requirements
Perform a gap analysis and developing guidelines for the use of
wireless technologies.

Remaining slides focus on the application
communication requirements
Grid-Interop 2009
Some Useful Definitions
•
•
A Smart Grid application is an entity communicating with one or
more entities
The communication requirements are quantitative constraints
placed on the communication infrastructure used regardless of the
medium used

Grid-Interop 2009
Approach
•
Develop a set of characteristics to capture the application
communication
–
–
–
–
•
List a representative set of Smart Grid applications
–
–
•
•
•
How much data is being exchanged?
How often is the data being exchanged?
How much delay can data delivery incur?
Who are the recipients of the data?
Identify different applications or applications with different characteristics
Applications belonging to a different Smart Grid domain are not
necessarily different from this stand point
Place characteristics and application types on a two dimensional
matrix where columns represent the characteristics and rows
represent application types
Devise a taxonomy for applications with similar network requirements
Fill out matrix entries

Seeking Input
1. Related to the application characteristics – or columns
in the matrix:
•
Do you have any comments on the columns capturing the
characteristics? Are there any missing columns?
2. Related to the application types – or rows in the matrix:
•
Are the rows representative of the Smart Grid space and
domains? Are there any missing applications?
3. Related to the quantitative requirements – or matrix
entries:
•
Do you have any numbers, aware of any numbers, reports that
contain numbers?
