The issue of Big Data (BD) was introduced relatively recently as the enormous amounts of data became available through the space exploration, weather forecasting and medical biogenetic investigations. Social media and outlets such as Google, YouTube, Facebook and others have also faced similar problems of handling huge data sets. The focus of this webinar is on different BD sources in the utility industry that range from field measurements obtained by substation/feeder intelligent electronic devices, to specialized commercial and/or government/state databases: weather data of different types, lightning detection data, seismic data, fire detection data, electricity market data, vegetation and soil data, etc. Due to the massive amount of such data (terabytes) available in real time, and through historical records, processing and management of such data requires revisiting data analytics used in the BD industries such as banking, insurance and health care. This webinar will point out the BD characteristics in the power industry where the temporal and spatial properties, as well as correlation to the power system and component models are necessary for an efficient data uses.
