June 23, 2009

2. 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

4. Grid Modernization Existing New Goal Requirements
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.

6. Renewable Generation Major sources Issues
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

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

8. 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 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
