Design Study of a Hybrid Power System for a Ferry Using Open Simulation Platform

Abstract

In a hybrid power system, an energy storage device unlocks the possibility of optimizing the design and operation. Only a properly tuned control strategy with correctly sized machinery under specific operation profiles will maximize the benefit. Therefore, a proper design should be chosen with consideration for the system behavior including the control strategy. This can be achieved using a dynamic system simulation. In this paper, a design study of a hybrid power system for a ferry is presented as a proof of concept for using Open Simulation Platform (OSP) for a design study at an early design stage. A complete system for a vessel and the power system is set up using the models contributed by different parties. A large number of sets of design parameters are created by the design of experiments. Results of simulations are presented, and the range of proper designs are selected based on the chosen criteria. A design tool was developed to integrate these processes for efficient use of the methodology. This study has successfully demonstrated the feasibility of the collaborative system design using co-simulation software from OSP.
