A Novel Framework Architecture for Distributed Digital Twins in Power Systems

This paper presents a comprehensive approach of a novel framework architecture for distributed digital twins (DTs) in power systems. This scientific work is a part of the research project AUTOGRID1, which goal is the development and investigation of new methods and algorithms to increase the automation-level for the distribution grid operation based on distributed DTs.. A higher automation level is required in order to maintain the stability and safe operation of the grid under high penetration of renewable energies and power electronic devices. In this sense, the DTs are an important part of this project, because they allow enhancing the system observability, capture systems dynamic and adapt the DT models according to changes and events in the real systems. Hence, this paper describes a framework architecture for coupling multiple DT models, their requirements and the implemented functionalities in each DT.
