在由多个分布式电源组成的直流微电网中，由于系统中各变流器到直流母线的距离不同，线路电阻的不同会降低系统的均流精度。下垂控制在直流微电网运行控制中得到了广泛的应用。为提高均流精度，必须选择较大的下垂系数，但过大的下垂系数会导致严重的母线电压降，影响电能质量。针对传统下垂控制中调压与均流之间的矛盾，提出了一种基于改进模糊逻辑下垂控制的递阶控制算法。通过改进下垂曲线，同时解决了电压调节和均流问题。通过仿真验证了该算法的有效性。
In the direct current (DC) microgrid composed of multiple distributed generations, due to the different distances between various converters and the DC bus in the system, the difference of the line resistance will reduce the current sharing accuracy of the system. The droop control was widely used in the operation control of the DC microgrid. It was necessary to select a large droop coefficient to improve the current sharing accuracy, but a too large droop coefficient will lead to a serious bus voltage drop and affect the power quality. In view of the contradiction between the voltage regulation and load current sharing in the traditional droop control, a hierarchical control algorithm based on the improved droop control of the fuzzy logic was proposed in this paper. By improving the droop curve, the problems of voltage regulation and current sharing were solved simultaneously. The effectiveness of the algorithm was verified by simulation.
