Big Data applications in power systems

In the last years, the term Big Data (BD) is becoming ubiquitous in almost every scientific field given the information era we are living. In this respect, power systems is not the exception. This overflood of information can be overwhelming for the different energy stakeholders, nonetheless, numerous opportunities can also be derived from this BD. To do so, it is necessary to perform the corresponding knowledge extraction to this large data. This has been referred as Big Data Analytics (BDA) in the recent literature. In this respect, this work provides a comprehensive understanding of the attributes of BD in the power sector, along with the most representative tools, techniques, applications and challenges related to the incorporation of BDA in this field.
