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-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
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
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
