What is a Smart Grid?

Supports Energy Efficiency

Modernization of Grid

Demand Response

Supports Renewable Generation

Support Distributed Energy Resources
Energy Efficiency


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




Micro-generation
 Micro-turbines
 Fuel cells
Energy storage
 Ice energy storage for AC
 Rechargeable batteries
Plug in Electric Hybrids (PHEVs)
 Vehicle-to-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
