Digital Twins for Electric Grids

This article describes the main applications of digital twins in operating a digital substation. It evaluates the associated features and benefits that are covered herein applicably to transmission and distribution grids alike, since they differ in their fundamental operating principles when it comes to modeling. Normal and emergency operation of a real substation is modeled to demonstrate the informativeness and control capabilities of a digital-twin enabled facility. The technology improves the informativeness of automatic control system while also being capable of automated analysis of controlled parameters for comprehensive representation of the substation's operating status.
