AI中文摘要：
大规模AI数据中心（AIDC）的快速扩张正在引入新的稳定性挑战，尤其是在具有快速阶跃式负荷变化以及对电压和动态性能有严格要求特征的弱电网或低惯量网络中。本文研究了使用构网型（GFM）增强型STATCOM（E-STATCOM）来支持此类设施的可靠集成。开发了一种基于功率导纳的线性建模框架以捕捉系统交互，并通过详细的电磁暂态（EMT）仿真进行了验证。结果表明，E-STATCOM对突然的负荷变化提供了快速、良好阻尼的响应，同时有效缓解了低频振荡以及与电网谐振的交互。通过负载均衡器、虚拟阻抗和协调的有功-无功功率支持实现可调动态行为，所提出的方法能够精确塑造系统响应，并在连接点改善调节性能。这些特性使E-STATCOM成为将大型数据中心集成到弱电网和长距离输电系统中的灵活且可扩展的解决方案，并辅以面向设计的框架，该框架便于参数选择和性能评估，而无需大量依赖EMT研究即可满足电网规范和AIDC互联要求。
英文摘要：
The rapid expansion of large-scale AI data centers (AIDC) is introducing new stability challenges, particularly in weak or low-inertia networks characterized by fast, step-like demand variations and strict requirements on voltage and dynamic performance. This paper investigates the use of grid-forming (GFM) Enhanced STATCOMs (E-STATCOMs) to support reliable integration of such facilities. A power-admittance-based linear modelling framework is developed to capture system interactions and is validated through detailed EMT simulations. The results demonstrate that E-STATCOMs provide fast, well-damped responses to abrupt load changes while effectively mitigating low-frequency oscillations and interactions with network resonances. By enabling tunable dynamic behavior via a load balancer, virtual impedance, and coordinated active-reactive power support, the proposed approach allows precise shaping of system response and improved regulation at the point of connection. These features make E-STATCOMs a flexible and scalable solution for integrating large data centers into weak grids and long transmission systems, supported by a design-oriented framework that facilitates parameter selection and performance assessment without extensive reliance on EMT studies to meet grid codes and AIDC interconnection requirements.
