Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

9. Atomic Structure
• Valance Electrons: are the
electrons in the Outer most
Shells.
• Max No of Valance
Electron is 8 and the 8
electron is the stable state.
To attain Stability the
Electron may lose or gain.
• Free Electrons: are valance
electrons having very weak
attachment with the
nucleus(Lose for stability)
Electrons are able to lose or gain
energy and to move (Excite) from one
orbit to another. Electrons have
Potential energy due to the nucleus
and kinetic energy due to the motion.
Electron requires energy to escape
from the atomic nucleus. Number of
outer most electrons is called the
valance of the atom. For a stable
atom, the valance number should be
eight. Atom has a tendency to attain
stability. For this, they lose, gain or
share electrons

10. Energy Bands: • Valance Band: is the energy
band of outer most orbits.
• Conduction Band: is the energy
band of conduction band (the
minimum energy required to
an electron is free).
• Conductors
• Semi Conductors
• Insulators
Consider a particular orbit of an atom;
each electron in the orbit has different
energy. In a Semiconductor (Crystal), a
number of such atoms are there. So a
particular Shell or Sub shell have a an
energy band (Collection of Energy
levels),instead of a single energy level.
Such bands are called energy bands.
