摘要:

直流微电网中含有大量的电力电子变换器，这些变换器在闭环控制下表现为恒功率负载特性，可能会引起直流微电网的稳定问题。提出基于线性状态反馈的直流微电网稳定方法。该方法通过引入线性状态反馈支路，抵消了恒功率负载的影响，从而确保了整个直流微电网稳定运行。仿真实验结果验证了所提方法的可行性和有效性。

Abstract:

There are a lot of power converters in DC microgrid and they are presented as constant power loads in the close-loop control, which may cause the stability problem. A method of DC microgrid stabilization based on linear state feedback is proposed, which introduces a linear state feedback branch to counteract the impact of constant power loads, ensuring the stable operation of whole DC microgrid. Simulative and experimental results verify the feasibility and effectiveness of the proposed method.

Key words: DC microgrid stabilization linear state feedback Buck converter Boost converter
