本文构建了超大规模数据中心的显式动态模型，包含其 heating, ventilation, and air conditioning (HVAC，供暖、通风与空调) 和 uninterruptible power supply (UPS，不间断电源) 子系统，并将这些模型整合到小信号稳定性框架中，以研究数据中心需求响应对电力系统区域间振荡的影响。通过特征值分析和时域仿真，结果表明基于UPS的需求响应可增强区域间振荡阻尼；相比之下，HVAC子系统因热响应带宽有限，固有地无法提供有效的振荡阻尼。采用基于梯度的优化算法调整UPS控制器增益，以最大化关键区域间模式的阻尼比，所提方法的有效性通过IEEE 39节点测试系统得到验证。
英文摘要
This paper develops explicit dynamic models of a hyperscale data center, including its heating, ventilation, and air conditioning (HVAC) and uninterruptible power supply (UPS) subsystems, and integrates them into a small-signal stability framework to investigate the impact of data center demand response on power system inter-area oscillations. Through eigenvalue analysis and time-domain simulations, the results demonstrate that UPS-based demand response can enhance inter-area oscillation damping. In contrast, the HVAC subsystem is shown to be inherently incapable of providing effective oscillation damping due to its limited thermal response bandwidth. A gradient-based optimization algorithm is used to tune the UPS controller gain to maximize the damping ratio of the critical inter-area mode. The effectiveness of the proposed approach is validated using the IEEE 39-bus test system.
