What is Smart Grid?

A DoE initiative that takes advantage of modern technologies to address the growing and changing needs of customers.

SmartGrids integrate communications networks with the power grid in order to create an electricity-communications superhighway capable of monitoring its own health at all times, alerting officials immediately when problems arise and automatically taking corrective.

Modern Technologies:– Advanced Sensors– Communication– Advanced Control Devices

Results:– Distribute electricity more effectively all the way from transmission to

customer appliances.

– Advanced Components– Improved Interfaces/Decision

Support

What is Smart Grid?

Three Key Areas

Applications Communication Devices

What is Smart Grid?

Modern Smart Grids should:– Detect and address potential problems– Acquire inputs from measurements over a rapid communication

network to diagnose problems and quickly restore network stability.

– Automatically adapt protective systems to changing network configuration

– Re-route power flows, change load patterns, improve voltage, and correct network in a matter of seconds

– Enable distributed resources to participate in operations– Improve reliability and security– Provide advanced visualization tools to manage network

Why Smart Grid?

Consider some of the economic consequences of power losses:– Power interruptions and disturbances cost the U.S. electricity consumer

at least $79 billion per year– A recent rolling blackout caused an estimated $75 million in losses in

Silicon Valley alone. – When the Chicago Board of Trade lost power for an hour during the

summer of 2000, trades worth $20 trillion could not be executed.

Our nation is increasingly held back by an outdated power delivery infrastructure. – The U.S. grid faces shortcomings in capacity, reliability, security and

power quality. Designed in the 1960s or much earlier, much of this critical national asset is well beyond its design life.

Characteristics of SmartGrid

Self-Healing– Real-time self assessments to detect, analyze, respond, restore

grid components.– Minimize interruption time– Identification of problematic devices– Communication with local/remote devices to analyze faults, low

voltage, poor power quality, overloads, and other negative conditions.

Customer Demand Motivation– Provide real-time information to consumers (cost/value)– Demand Response (DR) to shift peak demand– Real-time pricing

Characteristics of SmartGrid

Resists Attack– Minimizes consequences of attack– Security protocols will include; deterrence, prevention, detection,

response, and mitigation.– Technologies include; authentication, encryption, intrusion

detection, and filtering of alarms & communication.

Optimization of Assets Usage– Network will work only as much as needed.– Quality and capacity will be monitored in real-time.– Equipment failure rates and maintenance cost reduced.

Future Smart Grid?

What will the Future Look Like?

“SmartGrid means you fill up your car with hydrogen but cannot drive it the next day, because your teenage daughter has sold the hydrogen as electricity at peak tariff over the internet, and used the proceeds to charge her mobile phone card.”
