The study on a ship energy management system applied rechargeable battery

Abstract

Recently, the study of energy saving technology of ships begins in earnest, as energy saving policiesare performed all around the world. SEMS (Ship Energy Management System) is one of the techniquesto increase energy efficiency by applying to a independent system like a ship and offshore. SEMS is composedof Cooling Pump Control System (CPCS), Renewable Energy Emergency Power Control System(REEPCS), Load Control System (LCS), and Heating, Ventilation, and Air Conditioning System (HVACS). SEMS is enable to increase energy efficiency and achieve integrated management through the interlocking ofeach system. Especially, it is possible to improve the flexibility of the selection of the generator capacity inconjunction with a rechargeable battery and renewable energy. In this paper, SEMS applied rechargeable batteryis proposed and simulated. By applying the rechargeable battery, it was confirmed that SEMS applied rechargeablebattery can be operated at optimum efficiency of the generator.
