Analysis of the Requirements of Technical Standards for Grid-Connected Distributed Power Sources

In recent years, the rapid growth of distributed power sources has promoted the development of their grid connection standards. This article introduces the current status of distributed power grid connection standards at home and abroad. Representative distributed power grid connection standards in North America, Europe and China were selected and compared from aspects such as power control, grid adaptability, power quality, safety and protection. Point out the main differences between distributed power grid connection standards in North America, Europe and China, and analyze the development trend of distributed power grid connection standards. It will facilitate the next step to study the impact of distributed photovoltaic power generation system grid connection on power quality and propose solutions.
