Today’s remarkable challenge of maritime transportation industry is the detrimental contamination generation from fossil fuels. To tackle such a challenge and reduce the contribution into air pollution, different power solutions have been considered; among others, hybrid energy-based solutions are powering many ferry boats. is paper introduces an energy management strategy (EMS) for a hybrid energy system (HES) of a ferry boat with the goal to optimize the performance and reduce the operation cost. HES considered for the ferry boat consists of different devices such as proton exchange membrane fuel cell (PEMFC), LI-ION battery bank, and cold ironing (CI). PEMFC systems are appropriate to employ as they are not polluting. e battery bank compensates for the abrupt variations of the load as the fuel cell has a slow dynamic against sudden changes of the load. Also, CI systems can improve the reduction of the expenses of energy management, during hours where the ferry boat is located at the harbor. To study the performance, cost and the pollution contribution (CO 2 , NO X , SO X ) of the proposed hybrid energy management strategy (HEMS), we compare it against three various types of HEM from the state-of-the-art and also available rule- based methods in the literature. e analysis results show a high applicability of the proposed HES. All results in this paper have been obtained in the MATLAB software environment. 1.Introduction Renewable energy resources (RESs) have received growing attention in supplying the required energy of different systems during the last years. e marine industry has also been affected by this trend. Application of renewable and clean energies for supplying the required energy of the marine vessels like small ships and boats is growing and this has led to introducing the concept of Electric Ferry Boats (EFBs) in the marine industry. Different combinations of fossil fuel-based resources and RESs such as diesel gener- ators (DGs), fuel cells (FCs), solar panels, storage batteries (SBs),andcoldironing(CI)[1–3]canbeusedintheEFBsfor supplying the demand and providing the propulsion force of these boats. In this situation, optimal energy management of the EFB is an important subject from the viewpoint of both ship owners and reliability concerns that should be con- sidered to reduce the operation cost while considering the operation constraints of the equipment. Optimal energy management of the marine vessels has been studied before in the literature. e authors of [4] provided an energy management schedule in the electric ship according to the Model Predictive Control (MPC) to optimize the concordance between power generators and batteries’ energy-saving under high-power ramp rate loads. e authors of [5] proposed manner-based energy man- agement by means of Fuzzy Logic (FL) and Proportional- Integration (P-I) control in an all-electric ship with only electric storage devices.
