The Smart Grid group is conducting research into informatics-driven scalable software architectures to address realtime power management in the domain of Smart Power Grids. This work is funded by the US Department of Energy as part of the five-year Los Angeles Smart Grid Demonstration project, to forecast and curtail power consumption by thousands of electricity consumers on-demand through large scale information processing and consumer pattern detection. We apply existing information technology techniques to and investigate novel algorithms and frameworks for this emerging application area of critical importance to global sustainability,

This cyberphysical domain provides unique challenges to many existing computer science algorithms, approaches and frameworks due to the data complexity, dynamism, scale and need for realtime response. Some of the research topics that we are exploring as part of this project are semantic information integration, complex event and stream processing, data analytics and machine learning, data security and privacy, and cloud computing platforms.
