摘要: 为改进传统下垂控制较差的电压调节的性能,本文提出了一种基于下垂控制的直流微网的分层控制策略,实现合理的电流和功率的分配,同时补偿母线电压的偏离。首先分析了传统下垂控制的特点及引发的电压偏离问题;其次引入二级控制器解决了电压跌落的问题,并分析二级控制器稳定性;同时给出了直流微网的三级控制的整体设计。最后在Matlab/Simulink环境下的仿真结果验证了该方法的有效性,且在dSACE实验平台上验证了下垂理论和电压跌落补偿。
Abstract: For the sake of improving the performance of poor voltage regulation of traditional droop control, this paper proposes a hierarchical control strategy of DC microgrid based on droop control, which can achieve a reasonable distribution of current and power, and compensate the deviation of the bus voltage. Firstly, the characteristics of the traditional droop control and the problem of the voltage deviation are analyzed. Then, the two stage controller is introduced to solve the problem of voltage sag, and the stability of the two stage controller is analyzed. In the meantime, the overall design of the three stage control of DC micro grid is presented. Finally, simulation results in Matlab/ Simulink environment verify the effectiveness of the proposed method, and experimental results are carried out to evaluate the droop concept as well as secondary voltage compensation.
