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

Home area networking


Distributed monitoring & control


Distributed energy resources


Goal


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


Requirements


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


Issues


Distributed nature of supply


Intermittency of supply


Forecasting supply (availability, adequacy)


Potential for decreased reliability


Distributed Energy Resources

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

impact reduction & other ancillary services


Smart Grid Enablers

communications


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
quickly


Applications


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