An efficient and reliable micro-grid doesn’t need to be large or

overly complex.

This could be several homes or several hundred homes – the generation & storage would

simply be scaled to accommodate the load.

Challenges •  Tower of Babel

–  Hundreds of communications methods – mostly proprietary, mostly insecure, mostly not scalable

–  Even when standards based, there are multiple standards and few well defined information models

•  Difficult to make the business case to integrate and interoperate –  A historical problem for substation automation –  Becoming easier for asset management – preventing a

single large transformer failure can save millions

Motivation to Get it Right

Hot Topic Utility Applications •  General Conservation

•  Minimize customer energy & carbon footprint

•  Demand Management •  Grid Cost Reduction •  Grid Reliability & Stability Increase •  Demand Generation Avoidance •  Demand Consumption

•  Build an Energy Information Economy •  Create a Home Energy Services Market •  AMI Tunneling and Submetering

Hot Topic Customer Applications •  Appliances that ‘Do the Right Thing’ •  Electric Usage Awareness & Understanding •  Consumption Behavior Modification •  Utility Program Participation •  Home Automation for Comfort and Conservation •  Integrating Solar & Wind at the Home •  Integrating PEVs & PHEVs •  Distributed Storage •  Many Others…

Smarter Devices •  Water Management

–  Mange hot water production more intelligently –  Pool pump controls

•  HVAC –  Smarter thermostats: comfort, efficiency and grid-aware

•  Storage –  When appliances can’t or won’t shed, grid reliability can still

be achieved. PEVs, big batteries, other. •  Lighting

–  Tightly manage lights fixtures and natural light/heat sources •  Energy Management Home Automation Systems

–  Portals, Displays, and Set Top Boxes •  Smart Appliances

–  Coordinated, time, event, and price aware

Consumption Understanding

•  Utilities Sell Electricity in many ways but have little concept of how individual customers use it

•  Customers Use Products & Services… but have little concept of electricity use or value

•  Products & Services use electricity… but have little concept of how and when to conserve

•  Energy Services bridge the gaps by giving the customer the ability to meet demand requirements and personal goals regardless

Architecting Energy Services •  Access

•  Connect energy services to energy consumers •  Understanding

•  Help consumers understand usage •  Help consumers understand behavior

•  Remediation •  Help a customer know what to do next •  Enable the next step •  Automate the next step?

Energy Service Experience

•  Screw up the energy service experience, and:

HAN devices end up in a drawer OR service phone calls are made AND

Investment is Lost!

AMIEnterpriseIntegration

Will it ever work together? •  How does one validate a real world end to end

integration? •  How does one validate integration with many vendors? •  How does one validate usability and simplicity overall? •  How does one validate real world security? •  There are 3100+ utilities •  There are many regulatory, ISO and RTO models •  There is retail, wholesale, regulated and deregulated

models •  There are Commercial, Industrial, and Residential

models •  The need for standards and interoperability

The Smart Grid Labs (north campus)

•  Scalability test equipment (meter to backend and multivendor) •  SCADA FEP, networks, cap banks, reclosers, switches, sensors •  7 AMI network vendors, 4 Meter vendors •  Multiple Appliance vendors (refrigerators, stoves, TVs, Washers,

Dryers, Hot Water heaters), many In Home Displays, Gateways, Thermostats, etc.

•  Many backhaul vendors (public, private) •  Many local premises network types (wired, wireless) •  Many backend systems (SAP, OMS, reporting, billing, etc.)

–  Messages to devices –  Meter disconnects –  On Demand Reads
