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
605/03/23
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 through an aggregation point

Traffic Characteristics of Smart Grid Applications• Large number of connected devices (e.g. 1K-15 K smart meters/sector )
• No mobility
• Devices typically remain attached to the network for monitoring and control
• Small burst transmission – Interval (periodic) meter readings: Multi-interval reporting, meter reading 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
• Higher reliability for Distribution Automation, alarms and event reporting
• Possible group transmission, for group-wide update of system parameters etc.
• Periodic software upgrades
• Low power is desirable to maintain continued operation during power outage

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
• Exploit low-mobility to reduce signaling in the network
• Exploit group addressing and control
• May need to support new device monitoring and alarm functions
• Support power efficient operation
1105/03/23
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
c) low power transmissions.
• Address Smart Grid requirements as part of IEEE 802.16p system
