“…Some authors have considered the ship movement as load and focused on the modelling of the hybrid propulsion system. This approach avoids the use of ship dynamics and minimizes the motor dynamics [6], [12]. Other authors interpret the coupling between ship and propulsion as an input of the first over the second.…”

“…Thereby a dynamical model that accurately represents the physical interactions in a ship can be suitable to get corrective feedback in the subsystems design. As a result, it can improve their capacities, such as ship's energy efficiency, resistance, stability, and maneuvering [6]- [8]. And it can be used in the previous verification of the ship's requirements to achieve any possible reduction in building costs and a more reliable model's feedback for getting the final design.…”

The objective of this research is to provide a tool that allows to quantify the power requirements, energy consumption and the efficiency of the propulsion system of a catamaran with two degrees of freedom according to its speed. Furthermore, it seeks to improve the design process from a phenomenological perspective that gives rise to a better reliability of the result. To achieve this, an electromechanical model is being developed by using the methodology for obtaining phenomenological-based semi-physical models. This model couples the dynamics of a geometry-known ship with its propulsion system, which is constituted by a propeller and a brushless direct current (BLDC) electric motor; at the same time, it uses data from computational simulations related to the hydrodynamics of the submerged components. Finally, the results of using the model with parameters of a specific catamaran and motor are presented. This model allows to properly couple the dynamics of a boat with two degrees of freedom.

In order to reduce fuel consumption and reduce the deviation between the final battery state-of-charge (SOC) value and the target value at the same time, a novel double-layer multi-objective optimization method is proposed, which adopts an improved ant colony optimization (ACO) algorithm and the equivalent fuel consumption minimization strategy (ECMS) considering mode switching. The proposed strategy adopts a two-layer structure. In the inner layer, the ECMS considering mode switching was adopted to optimize the working mode and working point, so as to achieve the goal of reducing fuel consumption. In the outer layer, aiming at the shortcomings of traditional ACO, the heuristic factor and adaptive volatilization factor were introduced. An improved ACO method was proposed to optimize the equivalent factor, so as to achieve the goal of reducing the deviation between the final value of SOC and the target value. In order to verify the effectiveness of the proposed algorithm, it is compared with the traditional ECMS strategy and the rule-based (RB) ECMS strategy. The simulation results show that the proposed energy management strategy combining an improved ACO algorithm with ECMS considering mode switching can reduce the energy consumption of the whole ship and control the battery power.

“…Required electricity of these ships can be generated by different resources like diesel and gas power generators, batteries, and clean energies like fuel cell, or by hybrid of these resources [2][3][4][5]. At the moment, the hybrid of diesel generators and batteries is known as a popular method for supplying the all-electric ships loads and reducing the emission [6,7].…”

Energy Management of Hybrid Diesel/Battery Ships in Multidisciplinary Emission Policy Areas

All-electric ships, and especially the hybrid ones with diesel generators and batteries, have attracted the attention of maritime industry in the last years due to their less emission and higher efficiency. The variant emission policies in different sailing areas and the impact of physical and environmental phenomena on ships energy consumption are two interesting and serious concepts in the maritime issues. In this paper, an efficient energy management strategy is proposed for a hybrid vessel that can effectively consider the emission policies and apply the impacts of ship resistant, wind direction and sea state on the ships propulsion. In addition, the possibility and impact of charging and discharging the carried electrical vehicles’ batteries by the ship is investigated. All mentioned matters are mathematically formulated and a general model of the system is extracted. The resulted model and real data are utilized for the proposed energy management strategy. A genetic algorithm is used in MATLAB software to obtain the optimal solution for a specific trip of the ship. Simulation results confirm the effectiveness of the proposed energy management method in economical and reliable operation of the ship considering the different emission control policies and weather condition impacts.
