中文摘要
构网型(GFM)电池储能系统(BESS)有助于提升风电系统的动态性能与鲁棒性,但其有功与无功功率间的固有耦合效应会降低系统可控性,影响功率精确调节。本文系统研究了风场中GFM-BESS的功率耦合问题,提出基于反馈线性化的功率解耦控制策略。首先建立暂态功率响应模型以刻画耦合特性,进而设计新型解耦控制方法调节GFM电压矢量参考值。随后构建系统小信号模型,从频域角度分析解耦动态特性并验证所提策略的有效性。最后通过MATLAB/Simulink及硬件在环时域仿真验证了该方案的可行性与优越性。
English Abstract
Grid-forming (GFM) battery energy storage systems (BESSs) offer a promising solution for improving the dynamic performance and robustness of wind power generation systems. Unfortunately, the inherent coupling between active and reactive power in GFM control degrades the system controllability, making accurate power regulation challenging. This paper systematically investigates the power coupling issue of GFM-BESS in wind farms and proposes a power decoupling control strategy based on feedback linearization. First, a transient power response model is developed to characterize the power coupling phenomenon. Based on this model, a novel power decoupling control strategy is proposed to adjust the voltage vector reference of the GFM. Then, a small-signal model of the system is established to provide a frequency-domain perspective for analyzing power decoupling dynamics and verifying the effectiveness of the proposed control strategy. Finally, the proposed scheme is validated through MATLAB/Simulink and hardware-in-the-loop time-domain simulations.
