“…This type of modeling is being conducted in much more complex ship power system architectures for which conventional computation times can be excessive. As a result, an automated partitioning and multirate approaches have been developed to permit significantly faster computations [20][21][22].…”

Abstract-Modern technology combined with the desire to minimize the size and weight of a ship's power system are leading to renewed interest in more electric or all electric ships. An important characteristic of the emerging ship power system is an increasing level of load variability, with some future pulsed loads requiring peak power in excess of the available steadystate power. This inevitably leads to the need for some additional energy storage beyond that inherent in the fuel.With the current and evolving technology, it appears that storage will be in the form of batteries, rotating machines, and capacitors. All of these are in use on ships today and all have enjoyed significant technological improvements over the last decade. Moreover all are expected to be further enhanced by today's materials research. A key benefit of storage is that, when it can be justified for a given load, it can have additional beneficial uses such as ride-through capability to restart a gas turbine if there is an unanticipated power loss; alternatively, storage can be used to stabilize the power grid when switching large loads. Knowing when to stage gas turbine utilization versus energy storage is a key subject in this paper. The clear need for storage has raised the opportunity to design a comprehensive storage system, sometimes called an energy magazine, that can combine intermittent generation as well as any or all of the other storage technologies to provide a smaller, lighter and better performing system than would individual storage solutions for each potential application.

“…The required computational effort has always been a challenge in simulating those systems. The computational effort in power system simulation is due to the single matrix formulation, system order, complex switching models, integration step size, and so on [24]. Different techniques have been tested to deal with the computational complexity, such as the proper utilization of computer hardware and more efficient computation.…”

The hybridization of power systems offers the low-emission and energy-efficient marine vessels. However, it increases the complexity of the power system. Design, analysis, control, and optimization of such a sophisticated system require reliable and efficient modeling tools to cover a wide range of applications. In this work, a typical DC hybrid power system model is developed using a bond graph modeling approach. Necessary component models of varying degrees of fidelity are developed and integrated to build a system model with reasonable accuracy. The developed system model, along with the rule-based energy management system, is used to simulate the entire system and to investigate the load-sharing strategies as well as the system stability in various operating scenarios. Moreover, the simulation results are validated with experimental results conducted on a full-scale laboratory setup of DC hybrid power system and with a ship load profile. The results show that the system model is capable of capturing the fundamental dynamics of the real system. The hybrid power system model is further used to analyze the bus voltage deviation from its nominal value. The computational efficiency presented by the system is fairly good as it can simulate faster than real-time. The developed system model can be used to build up a comprehensive simulation platform for different system analysis and control designs.

INTRODUCTION T HE International Maritime Organization (IMO) has proposed stringent regulations to reduce emissions and improve energy-efficiency from the shipping industry. The energy-efficiency, low-, zero-emission, and innovative technologies are being investigated to comply with the regulations [1]. The energy storage device (ESD) based zero-emission vessel is still challenging for all types of marine vessels due to the low energy density of ESDs [2], [3]. The low energy density of ESD is compensated by the conventional Manuscript

“…While this simulation technique assesses many metrics from a single simulation run, it is also the most computationally intense. This has commonly limited practice of this simulation technique to short time spans, reduced-order models [65], or average-value models [66]; however, due to the wealth of information arising from this simulation type, it is an important simulation technique and commonly used after steady-state assessments have been made [67].…”

Aspects of terrestrial microgrids and ship power systems are examined. The work exposes a variety of technical synergies from these two power systems to effectively advance their technologies. Understanding their overlap allows congruent efforts to target both systems; understanding their differences hinders conflict and redundancy in early-stage design. The paper concludes by highlighting how an understanding of both systems can reduce the investment in research resources.
