对高阶非线性直流微电网进行简化建模是大信号稳定性分析的有效方法.传统简化模型主要关注 LC 滤波器和线路阻抗等参数,难以分析换流器控制参数的影响,所建立的判据存在难以准确反映直流微电网稳定域的问题.因此,该文提出直流电压下垂控制换流器的具备完整状态变量集的改进等效电路模型,相比于传统简化模型,能更准确地刻画系统低频响应特性.基于混合势理论推导了直流微电网大信号稳定判据及其稳定域,并结合 LaSalle 不变集定理得到能量指标,以反映系统稳定性变化趋势.建立的稳定判据可指导控制参数优化,且能拓展到多端直流微电网的大信号稳定性分析.在多场景下仿真验证了所提改进等效电路模型和...

Simplified modeling has proven effective in analyzing the large-signal stability of high-order nonlinear DC microgrids(DCMGs).However,the traditional simplified models primarily focus on the parameters such as LC filters and line impedances,making it difficult to analyze the impact of converter control parameters.Additionally,the established criteria do not accurately reflect the stability region of DCMGs.To address these limitations,an improved equivalent circuit model with a complete set of state variables for DC voltage droop control convert...
