Modelling and Simulation Analysis of the Fuel Cell Hybrid Propulsion System

Abstract

Under the pressure of global energy shortage and severe environmental pollution, using new energy in ships will become the mainstream direction of future development. Compared to traditional single fossil fuels, the hybrid system composed of clean energy improves overall cleanliness. Hybrid power design has also attracted widespread attention in academia and industry. Therefore, this article introduces a hybrid propulsion system for ships. It combines Proton-exchange membrane cell (PEMFC) and cell. A simulation model for the propulsion system of hybrid electric ships was established in the MATLAB/SIMULINK simulation environment. It analyzes the ship's operating speed and power under different operating conditions and allocates the operating power to the hybrid power system through an energy control strategy. Finally, it compares and analyzes the optimization potential and methods of hybrid power systems. The results indicate that the modeling method and energy management strategy used in this article can effectively simulate the load changes and energy allocation of ships under different operating conditions, improving the stability and efficiency of fuel cells.
