基于补偿截距电压的直流微电网分级改进下垂控制研究
摘要:针对传统下垂控制方法存在的分流精度和母线电压偏差难以同时调节的矛盾，提出了基于补偿截距电压的改进下垂控制策略。首先，分析了传统下垂控制原理，指出了传统下垂控制的弊端。其次，提出了分级改进下垂控制原理，改进得到总的控制模型。最后，在Matlab/Simlink和PSCAD中搭建相应的数学模型和电路模型，计算并设置相应的参数，验证所提出的控制策略进行了稳定性和有效性。

Abstract：Aiming at the contradiction that the shunt accuracy and the bus voltage deviation are difficult to adjust at the same time in the traditional droop control method, an improved droop control strategy based on compensated intercept voltage is proposed. Firstly, the principle of traditional sagging control is analyzed, and the disadvantages of traditional sagging control are pointed out. Secondly, the principle of improved droop control is put forward, and the overall control model is improved. Finally, the corresponding mathematical model and circuit model are built in Matlab/Simlink and PSCAD, and the corresponding parameters are calculated and set to verify the stability and effectiveness of the proposed control strategy.
