Control Strategy of Hybrid Energy Storage System in Ship Electric Propulsion
2018 IEEE International Conference on Mechatronics and Automation (ICMA), 2018In ship electric propulsion and other energy storage applications, in order to ensure continuous and smooth output of energy, we often use two kinds of energy storage device mixed. In this paper, we use batteries and super capacitor device as mixed energy storage system.

Early Efficiency Estimation of Hybrid and Electric Propulsion Systems on Board Ships
2017 IEEE Vehicle Power and Propulsion Conference (VPPC), 2017This paper presents a methodology for evaluating different on-board power systems in the concept design phase. From an energy efficiency perspective, the potential advantages of a modern on-board power system are dependent on two major considerations: the design ratio between propulsion and auxiliary loads and the operational profile.

Bi-objective optimal design of plug-in hybrid electric propulsion system for ships
Energy, 2019Abstract Growing concerns about reducing fuel consumption and global greenhouse gas (GHG) emissions have forced the shipping industry to accelerate the development of plug-in hybrid electric propulsion systems (HEPSs). However, the design optimization of plug-in HEPSs with the single objective of saving fuel may result in increased GHG emissions ...

Modeling and simulation of a hybrid electric propulsion system of a green ship
2014 IEEE/ASME 10th International Conference on Mechatronic and Embedded Systems and Applications (MESA), 2014In this work, the hybrid electric propulsion system of a marine vehicle was modeled in MATLAB Simulink and SimPowerSystems. Models of each of the propulsion components were developed and incorporated into a complete system propulsion model. A rule-based supervisory mode controller was constructed which specifies the combination of onboard power sources

A control power module for a hybrid inverter systems to drive electric propulsion ships
Journal of the Korean Society of Marine Engineering, 2018갈수록 심화되는 환경문제에 대한 대책 방안으로 대기 오염물질 배출 저감을 위한 전기추진 선박 기술의 발전이 대두되고 있으며, 이러한 기술을 활용한 선박으로는 하이브리드 전기추진선박(Hybrid electric propulsion ship)이 있다. 하이브리드 전기추진선박은 발전기를 이용하여 생산된 전력과 배터리에 저장된 전력을 병용하여 인버터에 공급하며, 인버터에서는 교류전압으로 변환되어 선박추진기를 구동하기 위한 교류전동기에 공급하게 된다. 이러한 하이브리드 전기추진 인버터시스템은 배터리, 인버터, 교류전동기가 인과적인 관계로 접속이 되어 있어 어느 하나의 시스템에 문제가 발생하면 전체 시스템의 운전이 불가능하게 된다 ...
