考虑内外环交互作用的构网型电压源变换器小信号稳定性控制阻尼效应研究

Strong coupling of conventional dual-loop control in dq frame makes stability analyses for grid-forming voltage-source converters (VSCs) inconvenient, hence the interaction between outer and inner loops is often omitted. However, this interaction plays an important role in system stability. To reduce the system orders, a decoupled inner-loop control method is proposed for grid-forming VSCs. This m...
