This article presents a model of a marine power plant with hybrid power sources consisting of Proton Exchange Membrane Fuel Cells (PEMFCs) and batteries. The primary objective is to develop a system-level fidelity model of the fuel cell-fed marine power systems with real-time capabilities. The model encompasses various mechanical and electrical domains such as the air-supply and the hydrogen auxiliary sub-systems of the PEMFC system, the power management system, the DC electrical converters with average - value assumptions and thruster and propeller dynamics. Moreover, the PEMFC system model in this work is verified and tuned with the experimental dynamic behavior of a PEMFC with a power capacity of 500 kW for specific applications in the marine sector. The presented model can be implemented for investigating the system performance for simulator applications, designing high-level controls, sizing and optimization. Indeed, the modular approach of the bond graph modeling strategy provides flexibility in the configuration and capacity of the power sources, as well as storage for further studies. Furthermore, this model of the fuel cell-fed power system is practical for feasibility studies of various maneuvering operations with a potential of integrating with the co-simulation applications. In the end, a simulation with torque set-points to the thrusters consisting of load steps and noises are proposed to evaluate the system performance, the controller robustness, and the high-level control performance in load sharing.

Impact of Offshore Wind Power on System Adequacy in a Regional Hydro-based Power System with Weak Interconnections
Tande, John Olav Giæver; Korpås, Magnus (Peer reviewed; Journal article, 2012)This paper presents an innovative contribution in considering the combined effect of wind farms and grid transmission capacity on loss of load probability (LOLP), rather than just the effect of wind capacity alone.
