1 UCLA WINSmartGrid Connection -Wireless Internet Technologies for Smart Grid Rajit Gadh Director, UCLA WINMEC Director, UCLA WINSmartgrid Program Director, UCLA Wireless Media Lab 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 blackout in N.E. caused an estimated $7 - $10 billion in losses Other requirements Security Redundancy Reliability 10/2/
