Estimating behind-the-meter solar generation with existing measurement infrastructure
Date: July 11, 2pm
Speaker: Emre Kara
Real-time PV generation information is crucial for distribution system operations such as switching,
state-estimation, and voltage management. However, most behind-the-meter solar installations are not
monitored.Typically, the only information available to the distribution system operator is the installed
capacity of solar behind each meter; though in many cases even the presence of solar may be unknown.
We present a method for disaggreagating behind-the-meter solar generation using only information that
is already available in most distribution systems. Specifically, we present a contextually supervised source
separation strategy adopted to address the behind-the-meter solar disaggregation problem. We evaluate
the model sensitivities to different input parameters such as the number of solar proxy measurements, number
of days in the training set, and region size.
MacroBase: A Search Engine for Fast Data Streams
Date: July 18, 2pm
Speaker: Sahaana Suri (Stanford)
While data volumes generated by sensors, automated process, and application telemetry continue to rise, the capacity of human attention remains limited. To harness the potential of these large scale data streams, machines must step in by processing, aggregating, and contextualizing significant behaviors within these data streams. This talk will describe progress towards achieving this goal via MacroBase, a new analytics engine for prioritizing attention in this large-scale "fast data" that has begun to deliver results in several production environments. Key to this progress are new methods for constructing cascades of analytic operators for classification, aggregation, and high-dimensional feature selection; when combined, these cascades yield new opportunities for dramatic scalability improvements via end-to-end optimization for streams spanning time-series, video, and structured data. MacroBase is a core component of the Stanford DAWN project (http://dawn.cs.stanford.edu/), a new research initiative designed to enable more usable and efficient machine learning infrastructure.
