基于二重前馈自抗扰的构网型光伏微电网稳频控制策略
Frequency stabilization strategy for grid-forming photovoltaic microgrids based on dual feedforward active disturbance rejection control
摘要
Abstract
To address the steady-state frequency error and sluggish dynamic response of the virtual synchronous generator(VSG)in islanded microgrids,this paper proposes a grid-forming frequency stabilization strategy based on dual feedforward linear active disturbance rejection control.First,a linear extended state observer(LESO)with feedforward compensation and a linear state error feedback(LSEF)control law are designed to accurately estimate and compensate for system disturbances.Subsequently,the impact of control parameters on system stability is investigated through frequency-domain methods,providing guidelines for parameter tuning.The feedforward characteristics and anti-disturbance performance of the proposed strategy are also theoretically analyzed to verify its effectiveness.Finally,a digital simulation model and a hardware-in-the-loop experimental platform are developed to compare system frequency responses under various control strategies and disturbances.The results show that the proposed strategy effectively enhances the frequency stability of islanded microgrids.关键词
