Thee digital twin must accompact for thee dynamic nature of thee grid, including load variations, generation fron m removenables, and sources, and digitation.

Once thee model is built, it mutt be continuously calilated. This is done by comparaing thee twin 's preventions against actual measurements andd adjusting parameters to minimize error.
