Big Data in Electric Energy Field and Their Utilization

Abstract

Survey results are outlined on big data in electric energy field and their utilization. Large amount of data are being measured, stored, analyzed and utilized in many fields. Electrical energy field is no exception. The survey was conducted from 2014 to 2017 by Investigating R&D Committee for Big Data in Energy Industry and their Utilization Techniques, IEEJ. In this article, which is the first in a series of four related articles, `big data' in this field is characterized and defined, and summary of the survey results are given on existing data and their utilization in diagnosis and anomaly detection, energy supply/consumption planning and control, and emerging services.
