Delivering ancillary services with data centres

An overview of Demand Response: Key-elements and international experience

“…Data centers are also considered capable of providing a range of ancillary services [82]. Regulation services are constantly active and data centers could adjust their consumption according to the signals sent by the grid operator every few seconds.…”

A survey of challenges and solutions for the integration of renewable energy in datacenters

“…Most of the existing literature so far has focused on supplying datacenters with RES or improving energy efficiency. However, grid-connected datacenters can also provide ancillary services to the grid [191,192,193], i.e., they can absorb or supply power on short notice and participate in frequency regulation or reserves, for example. Such behavior can be obtained either by modulating the IT load [194] or using local storage resources, e.g., from existing UPSs or from supplementary storage units [195].…”
