摘要

本文首先建立了电力系统动力学中前馈-反馈控制结构的存在。随后，采用特定的非线性分析工具来研究子系统的固有特性：前馈转子子系统的Kuramoto耦合振荡器理论和反馈电压子系统的单调系统理论。最后，利用小增益定理分析了整个闭环系统的稳定性和控制参数的影响。实验结果进一步补充了理论结果。引入的分解-聚集策略有助于降低稳定性分析的复杂性，也为其他相互关联的非线性系统的动力学研究提供了见解。

An improved decomposition-aggregation strategy for analyzing power systems stability

This paper begins by establishing the presence of a feedforward-feedback control structure within power system dynamics. Subsequently, specific nonlinear analysis tools are employed to investigate the inherent properties of subsystems: Kuramoto Coupled Oscillator Theory for the feedforward rotor subsystem and Monotone System Theory for the feedback voltage subsystem. Finally, the stability of the entire closed-loop system and the impact of control parameters are examined using Small Gain Theorem. Test results are presented to further complement the theoretical findings. The introduced decomposition-aggregation strategy helps reduce the complexity of stability analysis and also provides insights into the dynamics study of other interconnected nonlinear systems.
