| 摘要: |
| 建立直流微电网的数学模型，分析得出直流微电网的小信号稳定区域。为扩大直流微电网的稳定区域，提出反馈线性化的直流微电网稳定方法。应用Lyapunov稳定性理论，通过非线性反馈控制，克服直流微电网中恒功率负载的非线性影响，使得整个系统线性化，并确保系统全局稳定。仿真实验结果验证了所提方法的可行性和有效性。 |

| Abstract: |
| A mathematical model of DC microgrid is established and its small-signal stable area is obtained by analysis. A DC microgrid stabilization method based on feedback linearization is proposed to expand its stable area. The nonlinear influence of the constant-power load in DC microgrid is depressed by the nonlinear feedback control based on the Lyapunov stability theory，which makes the whole system linear and stable. The simulative and experimental results verify the feasibility and effectiveness of the proposed method. |
