Convergence of Energy & Information

“Drowning in a Sea of Data, But Thirsty for Knowledge”

• Acquires and stores over 67,000 trends from campus systems as fast as 1 Hz

• All of the primary power generation sources

• 2.6 million square feet or 22% of the campus’ total buildings

• Capacity for capturing over 200,000 individual events per second and millions of data points to accommodate a globally unprecedented instrumentation level

– down to an AC plug socket,

– individual cells in electricity storage devices

– individual power converters on a solar panel

“The use of the many complimentary technologies and their integration into the grid is revolutionary, and it can demonstrate Smart Grid concepts are affordable and secure sources of energy … “ Petar Ristanovic, CAISO Chief Technology Officer, July 8, 2010

The UCSD Microgrid in 2010-2012 will be a CAISO Use Case to…

• Increase the use of digital information and controls technology to improve reliability, security and efficiency of the electric grid

• Identify the technical and policy barriers and solutions to synchronizing microgrids with the ISO system.

• Provide an opportunity to identify IT architecture required for reliable operation of micro grid with the bulk power grid.
