PI Controller for Energy Management System in Hybrid Electric Ship

Abstract

DC hybrid power systems are of interest for future low emission, fuel-efficient vessels. The hybrid electric ship is mainly dependent on electricity and so there is always a need for storage. PV panel, Batteries, Ultracapacitors (UCs), Fuel Cells (FC) are being used for the proposed HES as an electric power source or as a storage unit. The aim of paper is developing an energy management technique in which the hybrid electric ship utilizes the sources according to the requirements. This increases the efficiency of hybrid electric ship and reduces the fuel consumption and unwanted emission. The maximum power point tracking (MPPT) in fuel cells and PV panel is done using (P&O) algorithm. Diesel generator performs the energy management process when all the other sources are not in use
