Distributed control implementation for zonal MVDC ship power systems

In this paper, we present a potential distributed adaptive control architecture applied to a zonal medium voltage DC (MVDC) ship power systems. The power sharing in the MVDC network among distributed generators will be presented first. Second, the active and reactive power sharing among zones in the low voltage AC (LVAC) network will be addressed. The effect of control in LVAC network on the MVDC network and vice-versa regarding power sharing and voltage stability will be investigated in this paper for the first time. Simulation results in MATLAB/Simulink and PLECS validate the promising distributed control architecture for ship power systems.
