Mining Smart Meter Data for Improving Distribution Grid Observability
This event is free and open to the publicAdd to Google Calendar
This talk will present our research on enhancing power distribution grid observability using real utility data and machine learning techniques. We have received a large amount of smart meter, microPMU and SCADA data and associated grid circuit models from collaborating utilities. We will begin the talk by introducing our data and one real utility dataset that we share with the research community. By leveraging the smart meter data, we have proposed a multi-timescale learning model that enables utilities to infer hourly consumption patterns of unobservable customers using only their monthly billing information, thus significantly enhancing the grid observability. Further, the smart meter data has been used to develop a model free framework to estimate cold load pick-up and help utilities make decisions in service restoration.
