Abstract: In recent years, distributed power generation has achieved rapid growth. Multiple countries and international organizations have also issued and revised a series of grid connection standards. To study the development trend of international grid connection standards for distributed generations, this paper introduces the current status of grid connection standards for distributed generations at home and abroad. The paper compares the grid connection standards of Europe, Australia, and China. The standard power control is analyzed and the main differences are pointed out. The paper provides reasonable suggestions for domestic distributed power generation connection standards, enhances the understanding of grid connection standards by distributed generation manufacturers, and promotes the development of the industry.
