Q: How can big data impact/improve the typical grid operations? Can you please help me understand the typical data-set/parameters coming from various protection relays (Relion etc), RTUs, CBs, feeder metering and various digital instruments lying within new-age substations, which can be analyzed in real-time along with CEP to achieve actionable insights that can describe, predict and prescribe for best actions and improve the asset health while avoiding unsolicited break-downs/outages?

A: It is not completely clear how big data will or will not influence the typical grid operations. Some think that it might revolutionize the power infrastructure since a lot of data is generated in the grid already and little of it is really utilized to optimize operations. However, precisely because of the amount of data generated by various devices (IEDs) the architecture of these devices is increasingly more distributed rather than central, i.e. the decision making process is distributed at the level where the volume of data is manageable, rather than centralize the "big data" in one location. On the other hand, there is definitely room for optimization, especially in asset management where data from distant locations can be brought together and correlated. The time will tell.
