With the popularization of microgrid system especially in mining caves, remote islands, and other areas, the independent microgrid system greatly improves its quality of life and improves its working environment. However, the large-scale use of power electronic equipment makes the stability of the region’s independent power supply system decline, making it easy to cause serious consequences such as delinking in the face of different perturbations, the cause of which is mostly due to the irrational distribution of perturbation power. Based on this, this paper selects the parameters to be modified for the time scale by comparing the advantages and disadvantages of the two types of parallel systems, and then reasonably sets the ratio of key parameters according to the size of the perturbation to maximize the power supply duration and safety of components, and finally verifies its validity through Matlab/Simulink.
Key words: PQ control / VSG control / Parallel system / Power distribution
