									The IP-enabled grid – more than
       just smart meters

                       Overview
• Motivations:
  – utilities:
      • demand reduction (DR)  cuts expensive peak power
      • smart meters  avoid meter readers, better outage
        information
      • storage management  plug-in hybrids as energy storage
  – consumers:
      • cost reduction: DR, automated temperature adjustment
      • convenience: pre-heat/cool home, vacation home monitoring
• Integration with other communication
  technologies
     Components and Interactions

                                 “alert: power outage!”




  BPL
                     “wash at 1900”




                         “what’s the
                         projected cost of a
                         kWh at 1500?”
“charge at 2300”
          Future developments

• Appliances and lights with built-in
  networks
  – Zigbee (802.15.4), powerline
    Ethernet?
• Smarter commercial buildings
  – quantitative standards for energy
    efficiency rather than LEED list     more energy
                                         efficient than
                                          electronic
  – occupancy sensors for lighting and
    heating
           Need for integration

• Notification     power outage at
                    your parents’
                       house

• Data aggregation
  – feed energy usage into neighborhood data
    base
• Other
  – use cell phone GPS to predict home arrival?
  – use calendar to track absences?
                    What’s needed?
• Avoiding stovepipe systems
• No maintenance, no configuration
   – literally, plug-and-play
• Protocol and technology needs:
   – notification of events
   – control of devices (heating, appliances, vehicle, …)
   – discovery of other sensors and devices
• Some existing efforts, but often legacy
   – designed for commercial use (e.g., BACnet)
   – specific to one L2 technology (e.g., Zigbee)
   – cumbersome security (manual password configuration)
                      A role for SIP?

                                         NOTIFY
                                         “power outage!”




NOTIFY
“new rate: 15c/kWh”              MESSAGE
                                 “start wash!”
                   Conclusion
• Consider system as a whole
  – including home & building security
• Integration with other services
  – intelligence may not be in meter
  – not just home-local
• Security and zero maintenance: designed in, not
  bolted on
• Role for existing IP communications protocols?
