Abstract
This paper introduces a hierarchical framework for developing Digital Twins (DTs) of low-voltage electricity network components using a unified, modular approach. In this architecture, a core, component-agnostic DT with essential functionalities serves as the foundation, enabling the creation of component-specific DTs by layering relevant features on top. For example, an energy storage DT can integrate a state-of-health estimator block, while a building DT incorporates a solar PV DT, battery energy storage DT, and the building’s electricity network block. This modular approach unifies and simplifies development, enhances scalability, and ensures compatibility within complex DT systems.
