Exploration on Autonomous Unit of Local Autonomous Power Distribution Networks

To address the requirements of the new type power system construction, this paper puts forward a local autonomous power network architecture suitable for national conditions, and explores the concept of autonomous unit. Firstly, the basic structure of local autonomous power network is given, and the basic connotation and expression form of autonomous unit are defined. Secondly, the comparative advantage of autonomous unit is obtained by comparing with the existing new element combination form of distribution network. Finally, according to the autonomous unit division principle of “close within the unit, loose between the units”, the autonomous unit division is carried out by using the community division theory through Gephi. The results show that the proposed method can ensure the degree of electrical coupling between the nodes in the autonomous unit and give full play to the advantages of power complementarity in the autonomous unit.
