Smart Grid Reference Model (From SG-NET-diagram)

5 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 p focus on Smart Metering Distribution Automation

6 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 Monitor and control of distribution equipment

7 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 Conservative estimates for # of meters per sector. Assume Washington Dc example. ~ 1 SS/ 200 meter 1 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 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 Conservative estimates for # of meters per sector. Assume Washington Dc example. ~ 1 SS/ 200 meter 1 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.

9 Example Smart Metering Transmission Requirements
Category Description Frequency Data Size (bytes) Latency Reliability Comments Periodic Communication (Uplink) Multi-interval meter read Considered Residential Electric Smart Meter to DAP 12-24 transactions/day, readings at 15min-1 hour < 3 hours > 98% /3 hours DAP to Head-end 4-6 transactions/DAP/C-I meter/day < 10s 99% Aggregate statistics must be calculated Periodic Communication (Downlink) Metering Interval setup, Considered residential, electric DAP to Smart Meter 25 transactions/ 1K meters/day 25 5s 98% Head-end to DAP *source : Open SG requirements [1]

10 Example Smart Metering Transmission Requirements
Category Description Frequency Data Size (bytes) Latency Reliability Comments On-Demand Communication (Uplink) On-demand meter reads, Payments configuration Aggregate transactions must be modeled by a suitable arrival process Smart Meters to DAP Several transactions 100 5s > 98% DAP to Head-end 50-100 > 99% On-Demand Communication (Downlink) On demand meter requests, Pricing, configuration DAP to Smart Meters Several 25-50 >98% Head-end to DAP 50-150 Software Upgrades Few/year K 5 minutes ~99% Different for meters/DAP *source : Open SG requirements [1]

11 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

12 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

13 Summary & Recommendations
Smart Grid is an important use case for M2M communications Smart grid requirements apply to targeted enhancements in the IEEE p 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 p system requirements document (SRD)
