Notional all-electric ship systems integration thermal simulation and visualization
SIMULATION, 2012This work presents a simplified mathematical model for fast visualization and thermal simulation of complex and integrated energy systems that is capable of providing quick responses during system design. The tool allows for the determination of the resulting whole system temperature and relative humidity distribution. For that, the simplified physical

NSGA-II for joint generation and voyage scheduling of an all-electric ship
2016 IEEE Congress on Evolutionary Computation (CEC), 2016The non-dominated sorting genetic algorithm II (NSGA-II) is applied to the concurrent generation scheduling and load management of the isolated microgrid: the joint generation — voyage scheduling of an all-electric ship (AES). The AES uses integrated power generators and an energy storage system (ESS) to match its propulsion and service loads, thus ...

Economic and Environmental Generation and Voyage Scheduling of All-Electric Ships
IEEE Transactions on Power Systems, 2016An 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 ...

Thermal management of a notional all-electric ship electromagnetic launcher
Energy Conversion and Management, 2018Abstract 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), 2013Power 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, 2019Abstract 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.

Assessing the dynamic secure region for an all-electric ship model
2012 North American Power Symposium (NAPS), 2012Dynamic security is an important factor in survivability of all-electric ships. On the other hand, region-based security assessment methods are efficient for online applications. In this paper, a deterministic method is presented to assess Dynamic Secure Region (DSR) in all-electric ships.

All electric ships dependable design: Implications on project management
2014 AEIT Annual Conference - From Research to Industry: The Need for a More Effective Technology Transfer (AEIT), 2014Dependability has only recently become a unified theory, developing its own taxonomy, lexicon and methods. This newly formed discipline now regroups concepts defined and developed within international rules corpus in different areas of engineering, such as: aerospace, automotive, computing, etc.

Integrating the FEL on an all-electric ship
2012This 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.
