Abstract :
In order to make more rational and effective use of distributed generation (DG), microgrid has been put forward. However, the connection of microgrid has a fundamental impact on the protection of distribution network. A brief introduction of the structure of microgrid was given, and the potential impact of DG on the protection and autoreclosing was analyzed. Some protection methods were summarized, and the adaptive protection was adopted in this paper.
