UCLA WINSmartGrid Connection-Wireless Internet Technologies for Smart Grid

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.
