Optimized Electric Propulsion System Modeling and Simulation with Low Voltage DC Hybrid Power Systems

Abstract

Electrification of ship propulsion system with hybrid power systems created interest in modeling of all marine vessels. Reduction in the emission of green house gases, fuel consumption and efficient energy management with improved system dynamic performance is possible with hybrid power systems. With penetration of power electronic converters into power systems, ship board direct current distribution systems offer further more advantages such as space, weight saving and flexible arrangement of equipment. On board marine vessel consists of synchronous generator, energy storage system, fuel cell, photo voltaic array and induction motor drive. Power electronic converters are modeled through detailed model. Mechanical components are modeled with mathematical analysis approach. Power sharing among the proposed hybrid power system is observed in MATLAB/Simulink software.
