Computer Science & Engineering at the Nexus of Energy and Environment: A View from UCSD Microgrid

About the series


This talk examines how ‘microgrids,' which are self-managed grids with local cogeneration capabilities, can be used as testing grounds for the prototyping and testing of smart grid technologies.   Using the prototype of a microgrid at the campus of the University of California at San Diego, we present energy data that points to promising methods for operation of various types of buildings that leverage coordinated use of sensing, information processing, and building HVAC systems.

Based on measurements and analysis, we show that for the emerging class of ‘mixed-use' buildings - that is, buildings with a non-trivial component of energy use by IT equipment -- significant possibilities exist to reduce total energy use from 10% to 30% based on effective duty-cycling of the IT and HVAC equipment, without affecting the comfort quality or availability of the building and compute resources.  We examine the emerging computer science problems arising from energy arbitration, alternative energy sourcing and capacity provisioning for computational resources through dynamic deferral of energy loads.


Rajesh K. Gupta is a professor and chair of Computer Science and Engineering at UC San Diego, and holds the QUALCOMM endowed chair.  His research interests are in energy efficient systems that have taken turn towards large-scale energy use in recent years.  His ongoing efforts include energy-efficient data-centers and large scale computing using memory-coherent algorithmic accelerators and non-volatile storage systems.  He currently serves as EIC of IEEE Embedded Systems Letters. Gupta is a Fellow of the IEEE.
