Integrated control of power generation, electric motor and hybrid energy storage for all-electric ships

2016 American Control Conference (ACC), 2016
Ship propulsion shafts experience large power and torque fluctuations due to hydrodynamic interactions and wave excitation. The hybrid energy storage system (HESS) is an effective solution to address the impact of these fluctuations for all-electric ships.

Economic and Environmental Generation and Voyage Scheduling of All-Electric Ships

IEEE Transactions on Power Systems, 2016
An all-electric ship (AES) uses integrated power generators and an energy storage system (ESS) to match its propulsion and service loads, thus forming an isolated microgrid. Existing work has hitherto set the minimisation of the AES operational cost as the single optimisation objective, with the reduction of the greenhouse gas (GHG) emission merely ...

High-power electric drives for all-electric ships

2010
The use of electric drives for large ship propulsion is a spreading trend in today’s marine industry thanks to the benefits it brings not only in dynamic performance and noise reduction but also from an environmental and energy-saving viewpoint. In fact, using electric motors enables to operate on-board prime movers (diesel engines above all) close to ...

Thermal management of a notional all-electric ship electromagnetic launcher

Energy Conversion and Management, 2018
Abstract We present the development, coupling, and application of a quasi-3D multiphysics model of a notional all-electric ship electromagnetic launcher (EML) and a dynamic parallel-flow heat exchanger (PFHX) model to devise effective thermal management strategies for naval EMLs.

A novel control principle for all-electric ship power systems

2013 IEEE Electric Ship Technologies Symposium (ESTS), 2013
Power system of the all-electric ship (AES) constitutes an autonomous microgrid employing a variety of distributed energy resources, energy storage devices, and power electronic converters. Innovative strategies are required to ensure flexible and reconfigurable power delivery, robust fault management, and improved power quality. In this paper, a novel

Model Predictive DC Voltage Control for all-electric ships

Control Engineering Practice, 2019
Abstract With the advent of on-board Direct Current (DC) power and propulsion systems, the transmission and delivery of energy on board of ships can be carried out more efficiently as it is being done using conventional direct-diesel or Alternative Current (AC) power and propulsion systems.

Integrating the FEL on an all-electric ship

2012
This thesis examines the feasibility of placing the free electron laser (FEL) on the all-electric ship. The power required by the FEL and the tolerance of the FEL to vibrations is determined using computer simulations. Methods of reducing the vibrations using vibration isolation and active alignment are described.

Opportunities for all-electric ships in smart energy systems

2019
Greenhouse gas emissions have been a major concern in recent years where maritime sector has a significant contribution as well as in energy usage. Since maritime technology has begun to replace mechanical propulsion by electric propulsion, it gives the opportunity to replace conventional fuels with alternative ones such as electric batteries and ...

Modeling and simulation of an all electric ship in random seas

2010
This Masters thesis, conducted in support of the All Electric Ship (AES) early design effort, presents two computational programs for analysis and simulation: a full-scale, end-to-end AES simulator and an analytical performance and stability assessment tool for the ship's propulsion drive; the integrated power system (IPS).
