Multi-level model predictive control for all-electric ships with hybrid power generation

Power availability to preserve propulsion is a vital issue in the shipping industry which relies on persistent power generation and maintaining stability of system. Since introduction on-board all-electric Direct Current Propulsion Systems (DC-PPS) with hybrid generation, are more efficient compared direct-diesel Alternating (AC) configurations, there have been extensive investigations stabilization control enable robust reliable performance DC-PPS during different ship operations. In this paper, multi-level approach proposed for control. For goal, first, mathematical model each system component then, overall modeled state space format. Then, Model Predictive Control (MPC) DC voltage unlike conventional droop approaches, takes current generated by sources into account explicitly. The evaluated via several simulation experiments high fidelity DC-PPS. results paper lead enabling effective approaches constant loaded microgrids.
