Information & Communication Enabled Power Infrastructure
The use of advanced communication techniques to link all aspects of the electric grid together (from generator to consumer) with sensors and smart devices, in order to provide enhanced operational capabilities that:
1) Engage CONSUMERS with the ability to wisely use electricity, electric devices and new services (from smart thermostats to PHEV);
2) Ensure EFFICENT use of the electric grid (optimizing current assets while integrating emerging technologies such as renewables and storage devices); and
3) Enhance RELIABILITY (protecting the grid from cyber and natural attacks, increasing power quality and self-healing capabilities).
Acting on this Information Will:

View of the Smart Grid
There is no single definition of Smart Grid
Many define Smart Grid from 50,000 feet
Smart Grid
Includes aspects of transmission, distribution, generation, and in-home devices
Includes many technologies such as SCADA, AMI, Demand Response, Distributed Generation, Smart Sensors, Distributed Intelligence
AMI is a key part of the Smart Grid but not the only part
Large effort on leveraging AMI for the Smart Grid
Partnering and Interoperability will be a must for the smart grid.
Partnering with utilities, standards groups, and key technology partners to realize components of the smart grid

9. Smart Grid Benefits Utilizing AMI
<May 2009>
Smart Grid Benefits Utilizing AMI
Outage/Restoration Detection & Fault Location
Opportunity - Improve outage notification, restoration indication and fault location
Loss Detection
Opportunity – Losses are difficult to detect on the distribution network
Volt/VAR monitoring and control
Opportunity – Provide communications out to feeders
Load Flow / State Estimation
Opportunity – Distribution load flows are typically based on substation data and distribute loads based on transformer rating
Power Quality Monitoring
Opportunity – Provide power quality and voltage monitoring at key points in the distribution network
Outage Indices monitoring and calculation
Opportunity – Outage data may be manual, or estimated

Standards
Standards should enable future functionality of the Smart Grid - need to go beyond where we are today
Better, stronger, faster
Global standards are needed
Multinational issue
Need to be robust
Electric Meters field life of years
Water Meter Modules + battery field life of years
