Data centres in the ancillary services market

Providing regulation services and managing data center peak power budgets

“…We analyze two different types of data center operation where both peak shaving and regulation controls are present. The first case does not alter the average data center power demand as in the previous studies [6] [7], but increases the peak power threshold to match the allotted regulation capacity. Different than the previous studies, we show how the decision mechanism should be designed to consider peak power costs.…”

“…We use pricing from NYISO and CAISO to show the importance of the market data center participates in. Figure 2 shows the NYISO numbers from [6] and CAISO ones from their database [12]. , but it differs strictly from them as it also considers peak power budgets.…”

“…Some previous studies, e.g. [6], incorrectly assumed that the power demand of a data center providing regulation service does not change within a service interval. When the power is set to a value in […”

“…Chen et al [7] explore the ability of data centers to provide regulation services using dynamic server power capping techniques. Aikema et al [6] analyze a number of different ancillary services for data centers, including DR, spinning reserves and regulation.…”

“…There are a few recent studies that investigate the data center participation in the ancillary services market [6] [7] [8] [9]. Wang et al [9] model a distributed set of data centers and explore DR using VM migration.…”
