What is a Smart Grid?

Supports Energy Efficiency

Modernization of Grid

Demand Response

Supports Renewable Generation

Support Distributed Energy Resources

Energy Efficiency

Large untapped resource

50% load growth can be
met with programs

Time based rates

Customer feedback via Home Area Network

In home displays, Home Energy Management

Billing Options such as pre

Grid Modernization


Substation protection

Feeder automation

Distribution automation

VAR optimization


Home area networking

Distributed monitoring & control

Distributed energy resources


Integrate existing grid monitoring & control to new distributed & customer focused


New generation of distribution management systems

Pervasive & secure communications

Advanced analytics

Dynamic control

Demand Response

Key element is dynamic energy pricing

Allows consumers to see and react to pricing before they
use the energy

Studies show consumers are interested if they can save
10% or more

Demand response uses:

Economic dispatch to reduce generation costs

Socioeconomic dispatch where consumers respond for the
benefit of society as whole

Reliability dispatch to reduce/eliminate service interruptions

Key Success Factor

Consumers will want something simple
and accessible to interact with the grid. Set it and forget it.

Renewable Generation

Major sources

Wind : 2008 US overtook Germany as world’s leading
source (25 of 121 total GW)

1000 MW of Wind in Ks by end of year

Solar: US expected to take world lead this year


Distributed nature of supply

Intermittency of supply

Forecasting supply (availability, adequacy)

Potential for decreased reliability

Distributed Energy Resources



Fuel cells

Energy storage

Ice energy storage for AC

Rechargeable batteries

Plug in Electric Hybrids (PHEVs)

grid = source for on
peak supply

& energy storage

Goal of all distributed energy resources is efficiency,
demand distribution / peak shaving, environmental

impact reduction & other ancillary services

Smart Grid Enablers

Integrated Communications

Robust, integrated, two

Sensing and Measurement

Enhanced synchronized
distribution system measurement and monitoring

Advanced Components

Power system devices that apply the
latest in materials, energy storage, and electronics to determine
the grid’s behavior

Advanced Control Methods

Methods to monitor essential grid
components and enable rapid diagnosis and timely, appropriate,
response to any event

Improved Interfaces and Decision Support

Seamless, real
time applications that enable grid operators to make decisions


Linking consumers to producers and all elements
of the energy/resource value chain
