Smart Grid Requirements Drafted by Open SG
• UCA International User group: Open SG Communications WG– Drafting detailed flow of control and data information across all SG interfaces
– Characterizing communication requirements
– Input into NIST Priority Action Plan (PAP) 2 on “Wireless communications Smart Grid”
– SG Network requirements specification v4.0 [1].
• Several use cases considered – Residential & Commercial
– Customer, Distribution, Transmission
– Electrical, Gas etc.
• For IEEE 802.16p focus on – Smart Metering
– Distribution Automation
604/10/23
Smart Grid Interfaces Applicable for 802.16p
• Smart Metering (Commercial and Residential)
– Home Area Network
– Field Area Network
• Smart Meter to Data Aggregation Point (DAP)
– Wide Area Network
• Smart Meter to AMI Head-end
• DAP to AMI Head-end
• Distribution Automation
– Wide Area Network
• Monitor and control of distribution equipment
– Field Area Network
• Monitor and control of distribution equipment

Traffic Characteristics of Smart Grid Applications
• Large number of connected devices (e.g. 1K-15 K smart meters/sector )
• Stationary devices
• Devices typically remain “connected” to the network for monitoring and
control
• Typical data flows
– Interval (periodic) and/or multi-interval meter readings, requests, error
reporting
– On-demand meter readings: requests, responses, error reporting
– Parameter, service updates and commands, acknowledgements, errors
– Event and alarm reporting
– Pricing, payments, power charging rate (PHEV) information
804/10/23
Traffic Characteristics of Smart Grid Applications (2)
• Small burst transmission
• Higher reliability, access priority and latency for Distribution Automation
alarms and event reporting
• Periodic “high-bandwidth” software upgrades
• Possible group transmission, for group-wide update of system parameters,
software etc.
• Behavior during power outages: notify head-end and continue operation

Transmission Requirements for Distribution Automation
• Requirements are possibly more stringent than Open-SG requirements
• Significantly higher reliability
• Very low-latency on alarm reporting and control commands (tens of milliseconds)
• Large number of frequent “real-time” transactions
• Small burst transmissions
• Multicast signaling to support real-time signaling for mass number of devices
1204/10/23
Recommended Requirements for 802.16p
• Ensure network scalability for large number of devices and transactions
• Exploit intermittent, infrequent traffic and minimize operation in connected
state
• Improve random access and polling/paging mechanisms
• Address extremely low latency for large number of devices (Distribution
Automation).
• Exploit “stationary” devices to reduce signaling in the network
• Exploit group addressing and control
• May need to support new device monitoring and alarm functions
• Mechanisms to handle operation during power outages
1304/10/23
Summary & Recommendations
• Smart Grid is an important use case for M2M communications
• Smart grid requirements apply to targeted enhancements in the IEEE
802.16p PAR: a) extremely large number of devices b) small burst traffic
• Priority access w/ low latency and higher reliability should also be
addressed for Distribution Automation
• Low power transmissions my be required during power outages
• Address Smart Grid requirements as part of IEEE 802.16p system
