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

3
Components and Interactions
alert power outage!
BPL
wash at 1900
whats 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
• occupancy sensors for lighting and heating

more energy efficient than electronic
5
Need for integration

• Notification
• Data aggregation
• feed energy usage into neighborhood data base
• Other
• use cell phone GPS to predict home arrival?
• use calendar to track absences?

power outage at your parents house

Whats 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)

7
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?
