可再生能源日益融入现代电力系统，在弱电网环境中对电压和频率稳定性提出了先进解决方案的需求。本文表明，具有电网形成能力的增强型静止同步补偿器（E-STATCOM）在风电场应用中优于同步调相机（Syncon）。通过基于功率导纳的线性建模框架并经详细电磁暂态（EMT）仿真验证，研究表明E-STATCOM能提供卓越的次同步谐振（SSR）阻尼、更快的动态响应，并有效抑制直流分量、暂态过电压以及串联补偿引入的新振荡模式。与受机械惯性限制的Syncon不同，E-STATCOM提供可调控制、虚拟阻抗仿真和可扩展的故障电流支持。这些优势使其成为稳定可再生能源主导电网，尤其是长输电线路和串联补偿电网的更强大、灵活的解决方案。本文还旨在提供一个基准E-STATCOM设计标准，使输电系统运营商等利益相关者无需详尽的EMT仿真就能评估其适用性。
英文摘要
The increasing integration of renewable energy sources (RES) into modern power systems, particularly in weak grid environments, demands advanced solutions for voltage and frequency stability. This paper demonstrates that Enhanced STATCOMs (E-STATCOMs) with grid-forming capabilities outperform synchronous condensers (Syncons) in wind farm applications. Using a power-admittance-based linear modeling framework and validated through detailed EMT simulations, the study shows that E-STATCOMs provide superior damping of sub-synchronous resonance (SSR), faster dynamic response, and effective suppression of DC components, transient overvoltages, and new oscillatory modes introduced by series compensation. Unlike Syncons, which are limited by mechanical inertia, E-STATCOMs offer tunable control, virtual impedance emulation, and scalable fault current support. These advantages make E-STATCOMs a more robust and flexible solution for stabilizing renewable-dominated grids, especially those with long transmission lines and series compensation. The paper also aims to provide a benchmark E-STATCOM design criterion that enables stakeholders, such as transmission system operators (TSOs), to assess its suitability without the need for exhaustive EMT simulations.
