本文提出了网侧成型三相潮流（GFM-3PF），这是一种增强型牛顿潮流框架，用于在三相不平衡网络中建模单相网侧成型逆变器（GFM）。本文的贡献有三方面：1）开发了两阶段求解策略，基于正序初始化后进行三相相域提升，以实现鲁棒的大规模计算；2）纳入带受控互耦的相域不平衡网络建模，以及与相位相关、频率敏感的负荷表示；3）通过共同的下垂控制频率状态，将单相GFM母线模型直接嵌入三相不平衡牛顿潮流方程中。GFM-3PF在3母线、33母线和118母线测试系统上得到验证，展现了其准确性、鲁棒性和可扩展性。

英文摘要

This letter introduces Grid-Forming Three-Phase Power Flow (GFM-3PF), an augmented Newton power flow framework for modeling single-phase grid-forming inverters (GFMs) in three-phase unbalanced networks. The contributions of this work are threefold: 1) developing a two-stage solution strategy based on positive-sequence initialization followed by three-phase phase-domain lifting for robust large-scale computation; 2) incorporating phase-domain unbalanced network modeling with controlled mutual coupling together with phase-dependent, frequency-sensitive load representation; and 3) embedding a single-phase GFM bus model directly into the three-phase unbalanced Newton power flow equations through a common droop-governed frequency state. GFM-3PF is validated on 3-bus, 33-bus, and 118-bus test systems, demonstrating its accuracy, robustness, and scalability.
