Study, Modeling and Simulation of a Hybrid Ship Propulsion System

Abstract

In recent years, there has been a great deal of interest in hybrid propulsion systems that provide power improvement solutions for watercraft. In order to be able to exploit the hybrid propulsion systems, one must first understand the principles of operation, its constituents as well as the parameters that influence its production and the means to control them. It is also essential to classify different types of batteries and panels according to their applications and environments. Our study will focus on the use of fuel cell, photovoltaic panels, a generator and a battery in the propulsion of a ship, which will choose an electrical topology that meets the constraints imposed. To realize a good exploitation of the hybrid system it is necessary to study all the equipment and to highlight the parameters on which they depend. Hence, it is necessary to think about the use of various sources to power ship propulsion system and that will allow better performance and strengthen navigation security. In this paper, we firstly studied, series and parallel hybrid propulsion configurations. Then we established the modeling of this system. Finally, we gave a numerical simulation of the proposed hybrid propulsion system operation.
