Abstract
Electrification is a key technology to reduce maritime emissions. The International Maritime Organization (IMO) wants to reduce annual greenhouse gas (GHG) emissions from maritime transport by 50% by 2050 compared to 2008. Electrification is one of the solutions to reach this target. In this master thesis a Hybrid Battery Storage System (HESS) is considered to supply a fully electric ship. In this system we used two batteries, High Energy (HE) and High Power (HP). HE battery will be able to store large amounts of energy and will be able to take care of primary cycles and maintain cruising speed. HP battery can quickly release higher amount of power which will take care of maneuvering by giving higher acceleration time or in braking events. To better utilize both battery systems, we developed a control strategy to interface the battery systems and power electronic converters. Simulation is done in MATLAB/Simulink to study the management strategy of this hybrid battery pack. Bidirectional converters are used in full-active HESS topology. Results are validated in simulation environment using realistic load curve profiles.Description
