Application of Digital Twin Technology in Intelligent Digital Power Grid

In the era of digital economy, driven by both evolving technology and rising demand, the digital grid has become a new concept, a new way and a new idea for the construction and development of smart substations. This paper elaborates the concept of digital twin, based on which the connotation of digital twin grid is proposed, analyses the derived relationships of digital grid, constructs a digital grid architecture containing physical layer, sensing layer, transmission layer, data layer, platform layer and application layer, composes the operation mode of digital twin grid, and summarises the key technologies of digital twin grid, puts forward the application scenario of digital twin technology in digital grid It also summarizes the key technologies of digital twin grid, proposes the possibility of applying digital twin technology in digital grid scenarios, and provides a reference direction for the construction of digital twin smart substations.
