Geographically Distributed Voltage Control Using Digital Twin

The recent advancements of 4.0 technologies, especially Information and Communications Technology (ICT) and Internet of Things (IoT), have facilitated power systems to be remotely supervised and controlled. In the Smart Grid Architecture Model (SGAM), communication and information layers are the first two layers to be built on top of the component layer by integrating different protocols and data models. Along with renewable energy sources, which are intermittent in nature but add up to the flexibility of the grid, voltage stability has become one of the main research topics in recent years. In this paper, the authors demonstrate the solution to synchronize and exchange data between the grid and its different components via a digital twin (DT) model for a Geographically Distributed Voltage Control (GDVC) strategy. The proposed method will then be validated and carried out based on a real low-voltage grid in the East of France named SOREA.
