What is a Smart Grid?

• Supports Energy Efficiency
• Modernization of Grid
• Demand Response
• Supports Renewable Generation
• Support Distributed Energy Resources

3
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-payment

Grid Modernization

• Existing
• Substation protection
• Feeder automation
• Distribution automation
• Volt-VAR optimization
• New
• 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

5
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 worlds
  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

7
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

Smart Grid Enablers

• Integrated Communications Robust, integrated,
  two-way 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 grids 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
