3 Agenda Relevant Smart Grid Interfaces for IEEE 802.16 Smart Grid Requirements (NIST/Open-SG)Relevant Requirements for the IEEE p PARSummary & Recommendations3
5 Smart Grid Requirements Drafted by Open SG UCA International User group: Open SG Communications WGDrafting detailed flow of control and data information across all SG interfacesCharacterizing communication requirementsInput into NIST Priority Action Plan (PAP) 2 on “Wireless communications Smart Grid”SG Network requirements specification v4.0 .Several use cases consideredResidential & CommercialCustomer, Distribution, TransmissionElectrical, Gas etc.For IEEE p focus onSmart MeteringDistribution Automation

7 Traffic Characteristics of Smart Grid Applications Large number of connected devices (e.g. 1K-15 K smart meters/sector )Stationary devicesDevices typically remain “connected” to the network for monitoring and controlTypical data flowsInterval (periodic) and/or multi-interval meter readings, requests, error reportingOn-demand meter readings: requests, responses, error reportingParameter, service updates and commands, acknowledgements, errorsEvent and alarm reportingPricing, payments, power charging rate (PHEV) informationConservative estimates for # of meters per sector.Assume Washington Dc example. ~ 1 SS/ 200 meter1 Km cell (assuming 3 meters per circular cell)15,700 meters/sector (with % penetration : 1.5K-15k)2 km cells~63K meters/sector w/ 100% pentration.
8 Traffic Characteristics of Smart Grid Applications (2) Small burst transmissionHigher reliability, access priority and latency for Distribution Automation alarms and event reportingPeriodic “high-bandwidth” software upgradesPossible group transmission, for group-wide update of system parameters, software etc.Behavior during power outages: notify head-end and continue operationConservative estimates for # of meters per sector.Assume Washington Dc example. ~ 1 SS/ 200 meter1 Km cell (assuming 3 meters per circular cell)15,700 meters/sector (with % penetration : 1.5K-15k)2 km cells~63K meters/sector w/ 100% pentration.

11 Transmission Requirements for Distribution Automation Requirements are possibly more stringent than Open-SG requirementsSignificantly higher reliabilityVery low-latency on alarm reporting and control commands (tens of milliseconds)Large number of frequent “real-time” transactionsSmall burst transmissionsMulticast signaling to support real-time signaling for mass number of devices
12 Recommended Requirements for 802.16p Ensure network scalability for large number of devices and transactionsExploit intermittent, infrequent traffic and minimize operation in connected stateImprove random access and polling/paging mechanismsAddress extremely low latency for large number of devices (Distribution Automation).Exploit “stationary” devices to reduce signaling in the networkExploit group addressing and controlMay need to support new device monitoring and alarm functionsMechanisms to handle operation during power outages
13 Summary & Recommendations Smart Grid is an important use case for M2M communicationsSmart grid requirements apply to targeted enhancements in the IEEE p PAR: a) extremely large number of devices b) small burst trafficPriority access w/ low latency and higher reliability should also be addressed for Distribution AutomationLow power transmissions my be required during power outagesAddress Smart Grid requirements as part of IEEE p system requirements document (SRD)
