Get Beyond HypeRegulators get lots of fragmented messages about smart gridYet they have little opportunity to get perspective on its implications, especially outside a contested case in their states
What does it do now for average people and average businesses?How might smart grid change and integrate into people’s lives in the next years?

How to do itGet leaders who know what they are talking aboutThose that sell stuff, ask them to tone down the commercial and get to the essence– Not a trade show– Demonstrations part of the program

Electric Grid about More than Electricity
Three flows across integrated networks:ElectricityInformationMoney
The smart grid is a way to better facilitate and manage all those flows and transactions into a cooperative, collaborative, transactive, reliable system

![Page 9: Smart Grid Day at MWDRI - assets.fiercemarkets.net](https://reader033.fdocuments.net/reader033/viewer/2022060302/6293e2eb10cca110bb1b1a24/html5/thumbnails/9.jpg)
Smart Grid: technology and physical assets
Advanced hardware (power electronics, more efficient generation, meters, appliances and end-use devices, communications networks)Advanced software (better modeling and data analysis, linkage between applications, communications)Advanced materials (cables, silicon, superconductors, semiconductors)
To produce better grid efficiency and reliability using interoperability and distributed, interactive intelligence embedded across the network and its actors.
Smart grid supports efficiency, demand response, renewables, distributed generation, PHEVs…

And…Information– The value of electricity across time and place– The condition of the grid– The condition of the various elements of the grid – Presented to entities (people, institutions, devices) that
can use it, in ways that they can understand and act onCustomers– They consume, consider, respond, interact– They respond for reasons that may have nothing to do
with what utilities or regulators value

Make it easier for customersCustomers respond– To what they understand (prices, times,
interface)– If they care about what happens

Optimality is ElusiveMost smart grid descriptions talk about optimizing stuff – Minimal cost– Optimized for this or that– But optimization can only happen in a command-and-control
networkBut the essence of the smart grid is that multiple actors make independent decisions within a network of interrelated devices– Absent centralized analytics and command-and-control, we can’t
optimize, we can only make the various parts of the system work better internally, and then work well together
– Lots of local optimization and cooperation will produce a very good outcome even if it’s not “optimal”

InteroperabilityThe ability of two or more networks, systems,
devices, applications or components to exchange information between them and to use the information so exchanged, in ways that don’t inconvenience the userInteroperability requires interconnectivity and interaction agreement between hardware and software to enable effective communications, coordination and control.Interoperability is achieved when users’expectations to exchange and use information among various devices and software applications from multiple vendors or service providers are met or exceeded. 14

Home Area Networks: Distillation of Control 4 ppt
There is no one in-home communication standard now– They use Ethernet, WiFi, Zigbee
Homeowners want devices to work together– Easier in new and newer homes

Utility Information Portal (that’s a Television)
We watched a demo that showed – the various appliances controlled by messages
coming from the utility– Information presented to the customer
Preset responses by thermostat, lights, etc. that we could change

Appliance Manufacturer Perspective: Whirlpool
34
![Page 35: Smart Grid Day at MWDRI - assets.fiercemarkets.net](https://reader033.fdocuments.net/reader033/viewer/2022060302/6293e2eb10cca110bb1b1a24/html5/thumbnails/35.jpg)
Perspectives of WhirlpoolSignificant market share of manufacture of heavy duty appliances– The 800 pound gorilla
What will it take for smart appliances to be typical?
35
![Page 36: Smart Grid Day at MWDRI - assets.fiercemarkets.net](https://reader033.fdocuments.net/reader033/viewer/2022060302/6293e2eb10cca110bb1b1a24/html5/thumbnails/36.jpg)
Why did Whirlpool invest in energy management research?
• To reach beyond simple efficiency & explore demand response and time-based pricing
• Understand how appliance design could provide value in a smart grid environment utilizing DR, TOU, RTP, CPP, CPR etc
• To understand the consumer attitudes and expectations• Learn how we can help residential consumers manage
energy in a non-intrusive manner• Need to research both the technology and consumer
interactions in the energy managed home.36
![Page 37: Smart Grid Day at MWDRI - assets.fiercemarkets.net](https://reader033.fdocuments.net/reader033/viewer/2022060302/6293e2eb10cca110bb1b1a24/html5/thumbnails/37.jpg)
Considerations
• Is there a smart-grid impact on product design?• Greater differences in objectives revealed• The grid vs the utility vs the product
manufacturer vs the appliance vs the consumer– Consumer– Product manufacturer (e.g. Appliance, HVAC, HW)– Power utility– Grid Operators– Regulators
• Consumers, if not appropriately engaged, have been known to thwart a utility program.
37

DR Financial Questions
• Whose money is spend and whose money at risk?– Grid / ISO / RTO
• Reliability• Ancillary services / spinning reserves
– Utility• Risk management and avoided cost in open market
– Consumer• Purchases the smart-grid enabled product• Pays the electricity bill
– Manufacturer• Additional R&D and manufacturing cost• Logistic issues in a diverse energy environment
– Utility Technology Supplier• Renumerated for equipment designed & installed
Assurance of return 38

Two Device Categories
Persistent vs. Process‐oriented
Start-to-finish process
involving multiple steps, sensors, temperatures and consumables often performing the task upon other consumer products such as food, clothing, and dishes.
Single persistent task
such as:•
Maintaining room temperature•
Keeping water warm
---
Forced power interruption
---
may be acceptable limited options
also refrigerators also stoves & ovens

An “energy-managed appliance” could be defined as on able to:• Interpret messages from the utility
• React to conditions of the electricity grid
• Provide value to our appliance consumer that also
assists the utility industry and grid operators40
![Page 41: Smart Grid Day at MWDRI - assets.fiercemarkets.net](https://reader033.fdocuments.net/reader033/viewer/2022060302/6293e2eb10cca110bb1b1a24/html5/thumbnails/41.jpg)
Residential DevicesMany individual product sub-categories:
Air purifiersWashers & dryersOvens & rangesCountertop appliancesDehumidifiersDishwashersFabric freshenersFreezers
Water heatersMicrowave ovensRefrigerators & Ice makersRoom air conditionersTrash compactorsTelevision & Cable AudioComputer, network, broadband
Key Concept:
•
Each device type and model may have a different response depending on components, real-time status, design issues, nature of the request & consumer preferences.

• Simplify communications (grid messaging)• Document messages by objective• Motivate implementation and commercialization• Tariffs in plain English in standard format• Standard way to compute benefits
Enable Understanding:•
Regional differences are extreme
•
Legislative, tariffs, climate, hardware, consumer attitudes, expectations etc …
•
How do we compute benefits for the masses?• Can we create standard computational format, yet retain
regional and utility differences?
Steps to Realization

• 4,000+ sets of tariffs to deal with in US & CA• Motivation is extremely regional• Business case for product manufacturers is very
difficult to create and validate• Consumer motivation to purchase enabled products
• Determine value of DR• Ability to show the consumer:
• why they should participate (education & motivation)• convenient participation (painless or un-noticed)• how they will benefit (compensation)
Interesting Thought:• If “penny saved is a penny earned”, can we actually
spend that penny?

Steps to Success
• Tariff design to enable consumers and manufacturer understanding of benefits and business cases.
• Quantify value of home / device response
• Define objective‐based smart‐grid messages
• Appliance / device manufactures – determine how their products can respond– handle the consumer interface relative to their
products and consumer preferences
• Consumer incentives (purchase & cost of ownership)
• Development of a consumer installable DR module

Closing Thought on Whirlpool
Discussion pointed to a direction where appliance would have a standard (USB?) port into which modules for demand response, maintenance, troubleshooting, etc. would be used. In other words, communications to control appliance will be outside appliances with continuously improving functions to control

Characteristics of Commercial Buildings
Diverse– Big buildings attract most interest from vendors– All vintages of systems (pneumatic, electric,
digital), communications w/ other building systems often incompatible
First cost is key (so hardware can be tough)Customers tend not to churn vendorsService contracts, then upgradesBiggest focus: HVAC (lighting overlooked)51

Barriers to InteroperabilityInexperience (utilities, suppliers, regulators)Incomplete standards– And utilities/regulators not demanding them
Incomplete vision of what is possibleHard to make the leap

Interoperability ChecklistPeople don’t understand interoperabilityDecision-makers don’t understand how to recognize and implement interoperabilityEasy is good. Short and Easy is better.The more people make decisions affecting the grid with interoperability in mind, the faster we’ll get to a smarter gridA way to get started – always more details

Erich’s Concluding Thoughts to Regulators
Focus on defining desired functionalityCommunicate policy goals clearlyDevelop technology independent architectureConsider path of system evolution– Optimize locally first, global can follow
Use ways to objectively evaluateBe aware of progress already achieved

Chris’ Closing Thoughts for Regulators
Market transformation takes timeIncentives for transition are useful, but market consistency is most importantEducation and simplicity are criticalSystem is only as good as people in the system

Possible ObjectivesMake sure discussions are at the highest levelMaking useful information available where it is most useful– Info on individual HVAC system: useful to
HVAC vendor, not so useful for utility
