Abstract: Due to the rapid increase in electrical energy requirements in marine power systems (MPSs), and to reduce the consumptions of fossil fuel, there is an emergent need to utilize renewable energy sources (RESs) in MPS, which has been an attractive field of research. The aim of this research is to present a novel approach of energy management and ancillary services for a shipboard micro-grid (SBM) integrated RE sources. Therefore, a MPS with PV-WT-FC, Hybrid Energy Storage System (ESS) and Diesel generator (DG) has been developed to relate an exact mobile islanded shipboard microgrid. The Energy management system is based on multi agent systems. The system is proposed with three different agents which are generation agent, load agent and battery agent keeping the information about generation, load demand and battery condition of the microgrid system. Dynamic programming is used to design the algorithms of the presented energy management system (EMS). Load Frequency control has been considered to study ancillary services. The shipboard power system is designed using the transfer function models with above said generating and storage system. Grasshopper Optimization (GOA) based PIDF control technique has been proposed to investigate the performance of LFC scheme of proposed novel SBM. GOA and PSO optimized controllers have been designed and performance evaluation carried out with respect to the conventional Fuzzy and ANFIS controller. The system responses have been analyzed in this work which reveals that the controllers designed are much more significant than the conventional ones. The responses obtained from the proposed controller compared with the literature to justify the novelty and superiority of the proposed controller. Also, the results obtained from the EMS shows a significant reduction of fossil fuel consumptions for the designed microgrid
