5. 52/10/2016 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

6. 62/10/2016 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

7. 72/10/2016 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

10. 102/10/2016 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

11. 112/10/2016 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 requirements document (SRD)
