HOW BUILDINGS WILL COMMUNICATE WITH THE SMART GRID:
THE APPLICATIONS AND PROTOCOLS

ConnectivityWeek 2010
Communication Needs
• Utility Grid• Buildings• Vehicles• Vehicles• Energy Sources• Energy Storage
ConnectivityWeek 2010
Integration• Distributed Energy
Resources• Demand Response• Demand-side
• Plug-in Electric And Hybrid Electric Vehicles
• Thermal-storage Air • Demand-side Resources
• ‘‘Smart’’ Appliances And Consumer Devices
•
• Thermal-storage Air Conditioning
• Information And Control Options For Consumers
ConnectivityWeek 2010
Smart Building – Smart Grid Questions
• What are the attributes and characteristics of the connection between smart buildings and the smart grid?
• What are the applications?• What are the applications?• What is the communications interface?• How will it be addressed technically?• What could or will it mean for building owners
and facility management?
ConnectivityWeek 2010
Demand Response
• Grid initiating communications; buildings acknowledging the acknowledging the signal
• Response to a demand response notification can be manual or automated.
ConnectivityWeek 2010
DR Continued
• Building systems automatically respond - turning off lights and equipment, adjusting set points
• If the demand response is “anticipated” - scheduled.
• If it’s dynamic real time • If it’s dynamic real time communication
• Open standards‐based - XML, SOAP and Web services
• Standards for pricing formats/ time-of-day schedules to be established
• Requires enhanced building management systems.
ConnectivityWeek 2010
Distributed Generation (DG)
• Alternative on-site energy sources
• Buildings will both energy consumer and energy consumer and potential provider
• Integration require communication and verifying of the quality of the energy provided, security and safety.
ConnectivityWeek 2010
Energy Information to Consumers
• Real-time and historic data, the cost, the rate schedule the trends and the projected forecast
• Amount and cost of • Amount and cost of renewable energy sources; carbon content
• Weather forecasts• The quality and reliability of
the power Commercial customersmore granular, more technicalReporting for cap-and-trade, LEED, Energy Star or gov. req.
ConnectivityWeek 2010
Plug-In Hybrid Electric Vehicles (PHEV)
• Hybrid and electric cars -futuristic
• PHEVs recharged at off peak hours -store energy transferred to the grid transferred to the grid during peak.
• Depend on when the driver wants to use the car, how much the batteries are discharged and what the time-of-day energy rate is.
ConnectivityWeek 2010
Building Control Systems and Devices
• Success of the smart grid will depend on the control systems within the buildings.
• Buildings will need to • Buildings will need to integrate sub-systems,
• Provide more sensors and sub-metering.
• BACnet is identified in the first draft of operational standards
ConnectivityWeek 2010
Standards and Protocols
• Draft report in September.• 77 standards/specifications • 16 standards were initially
identified having strong consensusconsensus
• Expanded to 31 after public comment
• Added 46 standards were identified as potentially applicable
