Distributed Energy Management Strategy for Ship Integrated Energy System considering Energy Efficiency Operation Index

Abstract

With the extreme increase in the global warming, it is necessary to investigate the energy management problem (EMP) along with the consideration of low carbon emission for the ship-integrated energy system during the period of navigation. Firstly, a ship-integrated energy system model is constructed with renewable generators and conventional fuel-based generators, concerning the economic benefits and social benefits, simultaneously. Furthermore, a fully distributed energy management algorithm is proposed to solve the EMP with a lower energy efficiency operation index (EEOI) and lower operation cost based on the multi-agent system theory. Finally, the effectiveness of the proposed distributed energy management strategy is proved by simulation results.
