摘要 研究了微网中采用P-f和Q-V下垂控制的多个微型电源同时参与系统频率调节时的微网小信号频率稳定性问题。在考虑控制器单元、功率测量单元以及整个电路网络动态特性的基础上建立了微网的小信号状态空间模型。利用该模型求取了微网在不同稳态工作点的系统特征值,利用系统特征值分析方法和时域仿真方法分析了负荷阻抗变化、等效线路阻抗变化和下垂控制器的下垂增益变化过程中微网的小信号频率稳定性问题。 The frequency stability of a microgrid is analyzed, in which the frequency is regulated by different micro sources using P-f & Q-V droop control. A small-signal state-space model is built considering the dynamic characteristics of the controllers, the power measurement and the system circuit. The eigenvalues are calculated at different steady-state operation points using the small-signal state-space model. Then the eigenvalues and the results of the time-domain simulation are used to analyze the frequency stability when the load impedance, the equivalent line impedance and the droop gains change.
