Abstract

Abstract: The power system is closely related to the production activities of various industries and people’s life. The digital twin technology can be used to effectively monitor the operation of the power system， respond in time， and reduce unnecessary time and labor costs. Based on the introduction of the concepts of power system and digital twin， this paper summarizes the research on the modeling and application of digital twin in power system in recent years. A systematic review is conducted on the relevant achievments of digital twin modeling in power systems from five perspectives： geometry， physics， behavior， rule， and multi-scale. The application of power system based on digital twin is summarized from five perspectives： fault detection， fault diagnosis， scheduling， state evaluation and multi-purpose. Finally， the challenges of digital twin modeling and application in power system are summarized， and the future development direction is explored.

Key words: electric power system, digital twin, modeling, application
