Introduction – ISO New England Inc.

• Regional Transmission Organization – Independent of companies doing

business in the market

• Responsible for:– Real-time bulk power system

reliability– Administration and oversight of

wholesale electricity markets – Regional system planning

• Not-for-profit corporation– Regulated by Federal Energy

Regulatory Commission (FERC)

Smart Grid Defined

Smart Grid is the integration of different infrastructures:

– Traditional Power System technologies– New Power System technologies– Communications– Information Technology

All together implementing a new paradigm ofpower system design and control

Smart Grid Objectives • For Reliability

– More capacity from transmission and distribution resources– Intelligent devices that automate monitoring and respond to emergency

situations– Efficient production, movement and consumption of electricity– Tools and training to support control room

• For the Environment– Reduction in Greenhouse Gases– Greater penetration of renewables, energy storage and demand resources

• For Consumer Control– Transparency into electricity usage and prices– Opportunities for consumers to supply energy, capacity and ancillary

services

Communication Requirements

• Region wide Operations and Planning become more complicated under the Smart Grid– Requires frequent interaction among system control entities– More Choices and Uncertainty - Less time to react– Reliability of Communication Paths

• Standardization– Need standardized control functions and communication

protocols for use among power system control entities• Cyber Security

– Security (physical and cyber) is a key requirement and should be designed upfront as part of the Smart Grid

– NERC Critical Infrastructure Protection standards require compliance by all grid operators, transmission and generation owners
