Abstract
This paper deals with the ship power management system using energy storage system. Energy storage device is used for the improving energy efficiency and improving power quality and energy shifting etc. Representative examples of the energy storage device is a ultra-capacitors, flywheel battery and secondary battery. In order to select the most appropriate energy storage device to the ship, Comparing the energy storage device and analyzed. Among the comparison results of energy storage system, middle-large secondary battery was deemed most appropriate in conjunction with a ship power management system linked energy storage system is proposed.

The Purposed of this paper is the capacity selection of secondary battery and generator suitable ship for energy efficiency improvements of ship with applied the secondary battery.

Analyzed the operational data of each ship type in the actual operation date for capacity calculation of the secondary battery and generator suitable for ship. Analysis ship type is car carrier, container ship, LNGC and ship operation data such as a ship power consumption, operation mode time, heavy consumption usage time were analyzed. The simulation was performed using the LabVIEW program based graphic user interface and modeling the ship electric load was modeled through the analysis of ship power load. To improve the reliability of ship load modeling was added 10% of margin power load. Re-selecting the capacity of the generator based on the power date that analysis, it was established the capacity of the secondary required to this.

The simulation result shows quantitatively by comparing the ship power management system linked battery and exiting power management system using diesel generator specific fuel oil consumption. As a results, the ship power management system appling secondary battery can improved by 2% of ship electric energy efficiency was confirmed.
