The rapid growth of artificial intelligence workloads is increasing the scale and concentration of data center demand, creating new concerns for power system resilience under disruptive events. This paper extends a validated multi-time-step DC optimal power flow framework to evaluate the impact of aggregated data center demand on contingencyinduced unserved energy. Using an IEEE 30-bus system with flexible resources, we replace a conventional load at a contingency-exposed bus with an energy-matched constant data center load and examine two capacity-growth levels under generator derating, transmission line derating, and coupled derating. The results show that data center capacity growth substantially increases both system-level and data-center-bus unserved energy under transmission-constrained contingencies. Under coupled derating, the high-growth case increases total unserved energy from  \n3.203 MWh in the energy-matched case to 22.891 MWh. A supplementary energy-matched coincident-demand case further increases total unserved energy by 34.4%, indicating that temporally concentrated datacenter demand can amplify resilience impacts even without increasing total energy consumption.  \nKeywords: Contingency analysis · Data center · DC optimal power flow  \n· Grid resilience · Unserved energy.  \n1 Introduction  \n1.1 Motivation  \nData centers are becoming an increasingly important source of electric demand as artificial intelligence (AI) and cloud computing services expand. In the United States, data center electricity use reached approximately 176 TWh in 2023, representing about 4.4% of total electricity consumption, and is projected to reach 325-580 TWh by 2028, or approximately 6 .7%-12% of total electricity consumption [12] . Unlike gradual growth in conventional demand, new data center loads can be large, concentrated, and sensitive to interruption. The North American Electric Reliability Corporation (NERC) has therefore identified emerging large  \n2 Yuhan Du, Erika Ardiles-Cruze, and Javad Mohammadi  \nloads, including data centers, as a growing reliability concern because their magnitude and operational characteristics can affect transmission planning, resource adequacy, and real-time system operation [9] .  \nIn addition to their scale, AI-oriented data centers may introduce new temporal demand characteristics. A recent production data study of large AI training workloads reports synchronized power variations due to alternating computation and communication phases [2] . These fast variations are outside the temporal resolution of a dispatch model, but they motivate evaluating whether elevated data center demand overlapping with a grid disruption can further stress system operation. Recent data center modeling guidance also emphasizes that model fidelity should be selected based on the grid interaction being evaluated, ranging from detailed, fast-timescale representations to more tractable system-level abstractions [14] . Accordingly, this work studies data centers as aggregated gridfacing loads over a dispatch horizon and includes a simplified coincident-demand sensitivity case.  \n1.2 Literature Review  \nEarly studies on data center demand response demonstrated that computing workloads and local generation can be coordinated to reduce coincident peak demand and electricity expenditure [8] . More recent studies have extended this line of work toward grid-interactive data center operation.
