ABSTRACT
In this chapter, in order to have a relatively complete insight of the digital twin (DT) in the smart grid, its development and definition are first presented, followed by some applications and their corresponding DT modelling techniques. In the context of this chapter, DT is understood as a real-time digital representation of physical components based on measurement data and analytical knowledge. It enables power suppliers to transform operations with implementable insights to achieve improved commercial decisions. In other words, the power grid operator can improve operations, reduce unplanned outages and manage fluctuations in market conditions, fuel costs and weather conditions.
