UCLA WINSmartGrid Connection-Wireless Internet Technologies for Smart Grid

10/2/2009 2

Opportunity� While the current electric grid in the United States has an impressive 99.97% reliability, it is

somewhat limited in its ability to handle renewable energy sources (solar, wind, geo-thermal, biomass), to effectively manage demand response, to self-repair, or to sense/monitor its own problems.

� Current high-voltage transmission grid imposes constraints on deployment of renewables - wind, solar, and geothermal power due to absence of its reach in places where these sources exist (E.g. Nation has enough wind for 20% of national requirement, but is not accessible).

� Congestion hurts reliability of grid, esp. where new power sources originate

� Monitoring and control technology on transmission and distribution is weak

� Transmission congestion costs consumers in eastern U.S.$16.5 billion per year in higher electric bills.

� Smart Grid should reduce cost of power outages - 2003 blackout in N.E. caused an estimated $7 - $10 billion in losses

� Other requirements

� Security

� Redundancy

� Reliability

WINSmartGrid – Technology

Based on ReWINS� Low Power technology

� Open architecture

� Standards-based communications adapted to fit the problem resulting in lower overall cost

� Wireless infrastructure for monitoring

� Wireless infrastructure for control

� Two-way communication

� Service architecture with layers - Edgeware, Middleware and Centralware

� Over the air download for real-time reconfigurability with wireless

� Plug-and-Play approach to network installation

� Reconfigurability - The capability of the technology to be reconfigurable allows OTA (over the air) upgrade of the firmware to be able to handle different appliances, applications, sensors, controllers, thermostats, smart meters, PHEVs.

UCLA WINSmartGrid Research

Objectives of research- to determine what the wireless and sensor/monitoring communications architecture will look like for a scalable smart grid.- to determine how demand response functions in Smart Grids-to determine what the % reduction demand response will be in real-world scenarios- to study security issues within a wireless micro grid.- to connect various smart appliances and devices for studying scaling and performance of heterogeneous wireless infrastructure- open-systems to allow vendors to create plug-and-play sensor-enabled appliances- to investigate integration of PHEV and other energy storage systems- to study how variable, small and intermittent renewable energy sources would affect the last mile of the smart grid (distribution)- to propose data modeling and exchange frameworks for wireless sensors, nodes and controllers in commercial and residential settings
