What is the Smart Grid?

“…a web-enabled digitally controlled, intelligent delivery system”

Grid decisions are…

Too MANY

Too QUICK

…for human management

The Internet is Our Friend

Ability to Go Green

Real time and bidirectional

Quick and efficient response to disturbances

Being Green

Smart Grid – Increases efficiency

Saving up to 46-117 billion dollarsReduces electricity lost from 9% to 2%

– Rewards individuals for conservation

– Ability to integrate: small scale generation intermittent renewables

It’s not so hard after all!

Real Time Monitoring

Ability to assess power line volume

Information and power exchange between customer and supply

Reduced vulnerability to problems/threats – Data acquisition and transfer for self healing

Self-Healing

Digital Engineering Design That Enables:– Isolation/restoration of problems– Virtually no human involvement– Continuous assessment of problems

Predict, Detect, Respond, Resolve

Regulation

Net metering

Smart metering

Price Signaling

Curtailment

Net Metering

Receiving credit for surplus energy fed back into the grid.

Plugs in small scale energy generation into the grid.

Pre-cursor to the SmartGrid

Smart Metering

Digital records of power usage.

Automated heating/cooling/lighting.

Demand response programs.

Annual power demand reduction by…– 52-106 billion kWh – saving $3-7 billion / yr.

Meter prices will drop 50% in the next 3 years.

Price Signaling

Permits consumers to take overall grid demand (reflected in fluctuating prices) into consideration before and during energy usage.

Curtailment

The utility company will temporarily adjust your energy use to reduce demands on the grid.

GoodWatts Energy Management System

Allows both the homeowner and the utility to send commands to the home.

Benefits:– Remote management– Homeowners manage their own

energy consumption.– Continuous feedback to the

homeowner.

The Smart Grid and the West Coast

Bonneville Power Administration’s Wide Area Measurement System.

California’s Dynamic Power Pricing.

Ashland municipal utility’s Power Shift program.

Personal Energy Monitors

Smart energy industry: – $15 billion annually– Pacific NW: $2 billion share

Smart energy: application of digital information technology to optimize power:

– Generation– Delivery– End use

Rewards: – Energy conservation during peak demand– Purchasing “smart” technology appliances

Microgrids

Separate from larger grid

Reduced line losses (smaller area)

AC v. DC power

Wide Area Management Systems (WAMS)

Enabling Technology - advanced sensors

New tech. breakthroughs

2001-present : Consortium for Electric Infrastructure to Support a Digital Society – “Self-Healing Grid”

Challenges

BAU

No stable business climate

Performance-based ratemaking

Limited presence of smart technologies in public facilities

2010

Customer gateway for next generation smart meter – 2-way communication

Intelligent homes and appliances

Advanced conductors

Regional plans for modernization

Present 2010 2020 2030 The Future

2020

Improved energy management

Automatic corrections

High-Tech generators, transformers, cables

Long distance superconducting transmission cables

Present 2010 2020 2030 The Future

2030

Reliable, secure, digital-grade power for anyone

Affordable, pollution-free, low-carbon producing

Completion/continuation of superconducting framework

Present 2010 2020 2030 The Future

How we are making the future possible!
