Today, our “What is…?” series is about the term “digital twin”. This is an expression that comes up again and again and we are working on this principle with customers and partners. So we thought we’d explain it in more detail.

It is said that twins have a very special relationship to each other. Thoughts and feelings are partly exchanged, even over long distances. If one twin is doing very well or is in danger, then the sister / brother can sense this. Thereupon, the sibling can quickly assess the situation and help if necessary. – So they say.

Whether this is true or not, we do not want to judge. But where we agree: A digital twin has these characteristics and can therefore offer high added value!

What is a digital twin and how does it benefit us?

So what is a digital twin? A digital twin is a 1-to-1 copy of a system, for example a distribution network. Every device, every state, every measurement is integrated into a digital image of the network and constantly updated during operation. This means: If I operate the system, I have complete knowledge of the real copy of this system, no matter when and no matter where.

Why is this necessary at all? The question can be answered quickly: If I know my network at any time, I can quickly recognize dangerous situations (voltage drops, overloads, …) and intervene accordingly. I know the condition of the network at all times – if my network is doing well, I recognize that – if my network is doing badly, then I can (and should) help. And that even over long distances….

How exactly a digital twin is built, how it is programmed and how it is operated… There is no standard definition for this. It is only important that the core properties, such as the 1-to-1 copy of the network (at any time!), are fulfilled.
