| contents | The rapid growth of renewable energy sources has significantly reduced system inertia and increased the need for fast frequency response (FFR) in modern power systems. Data centers, as large and flexible electrical consumers, hold great potential to contribute to frequency stabilization due to their controllable IT workloads and on-site uninterruptible power supply (UPS) systems. This paper investigates the feasibility of leveraging data centers for providing fast frequency response through real-time workload modulation and UPS coordination. A dynamic model combining data center power consumption and grid frequency dynamics is developed, capturing the interactions between IT servers, cooling systems, and energy storage. Control strategies based on frequency deviation are implemented to adjust server power and discharge UPS batteries during frequency events. Case studies on a modified IEEE 39-bus system demonstrate that the proposed strategy can effectively reduce frequency nadir and shorten recovery time without compromising service quality. The results highlight the promising role of data centers as grid-supporting resources in future low-inertia systems. |
