Comprehensive Design of DC Shipboard Power Systems for Pure Electric Propulsion Ship Based on Battery Energy Storage System

Abstract

With the strengthening of international environmental regulations, many studies on the integrated electric propulsion systems applicable to eco-friendly ship are being conducted. However, few studies have been performed to establish a guide line for the overall pure electric propulsion ship design. Therefore, this paper introduces the comprehensive design of DC shipboard power system for pure electric propulsion ship based on battery energy storage system (BESS). To design and configure the pure electric propulsion ship, 2 MW propulsion car ferry was assumed and adopted to be the target vessel in this paper. In order to design the overall system, a series of design processes, such as the decision of the ship operation profile, BESS capacity selection, configuration of the power conversion systems for propulsion, battery charging/discharging procedures, classification of system operation modes, and analysis of the efficiency, were considered. The proposed efficient design and analysis of the pure electric propulsion ship was qualitatively and quantitatively validated by MATLAB Simulink tool. The methodology presented in this paper can help design real ships before the system commissioning.

“…However, the authors do not explain contradictions concerning the selection of the appropriate storage technology for the possible applications. The authors in [51] describe a design methodology for the battery energy storage system (BESS) of an all-electric DC-SMG. The proposed methodology, however, only optimizes the DC bus configuration for an assumed vessel with simplistic characteristics.…”

“…Thus, the less accurate approach can be considered sufficient for a preliminary study aimed at providing information to the designers in regard to the system architecture (for ship, port, and shore connection), to be selected and analyzed in depth in a later design stage with more complex approaches. Indeed, when more data about the system becomes available, more detailed ship energy analyses approaches can be used, such as the one shown in [9].…”

“…It is clear from these examples that there is no single solution to the issue, but different approaches can be successfully exploited to improve upon the actual environmental performance. The design of ship power and propulsion systems is also a hot topic [8][9][10], due to the similarities between shipboard and land based microgrids [11]. As an example, in [8] the authors apply the model-based approach to the design of a DC shipboard power system, by means of a multiphysics real-time simulator.…”

“…As an example, in [8] the authors apply the model-based approach to the design of a DC shipboard power system, by means of a multiphysics real-time simulator. Similarly, a battery based shipboard power system design is presented in [9], discussing different operation scenarios and using a MATLAB based model to validate the results. The optimal management of new onboard power sources and energy storage is another prolific research branch [12][13][14][15].…”

Simulation-Based Analysis of Dynamics of Autonomous Electric Power Systems

“…Authors [15] are devoted to the study of processes in industrial versions of asynchronous short-circuited electric motors. The analysis of processes in shipboard electric motor design was performed [16,17]. These articles contain theoretical and experimental studies of both direct start-up using resistance moments on the motor shaft that are different in size and nature, and adjustable start-ups.…”
