“…As anticipated, hybrid architectures can be considered among the most promising solutions to reduce pollution and greenhouse gas emissions [29]. Despite the reduction in fuel consumption usually related to the use of these technologies, their introduction on small vessels represents a technical challenge, due to the need to maximize the space for people and goods, consequently minimizing the space available for the energy storage and the propulsion system.…”

“…This configuration is characterized by the decoupling of the propeller from the ICE, allowing it to operate at peak efficiency; the efficiency increases obviously with the number of ICEs, as a consequence of a better partition of the required load. This solution can be problematic in small ships due to restrictions on volumes and weights [29].…”

Interest in designing more efficient and versatile ships comes from increasingly stringent regulations on emissions. In this context, a possible solution to overcome these limits may be the replacement of marine propulsion systems based on diesel engines with hybrid architectures. This paper provides a dynamic analysis of a hybrid marine propulsion system (HPS) consisting of an internal combustion engine and an electric engine coupled with a battery pack. A dynamic simulation of a daily working cycle was carried out based on a real load demand. The instantaneous behavior of each component was evaluated. A brief summary of the HPS performance, varying the battery pack capacity, was provided together with an estimation of its impact on the system efficiency. Referring to this last point, the adoption of a hybrid system has permitted a decrease in the specific consumption, on a given route, of about 2% with respect to the case where the propulsion is entrusted only to the diesel engine.

“…VER the last few years, especially after the Paris convection, which sets a target of keeping global temperature rise in this century well below 2 o C, more stringent restrictions have been applied or are due to be applied on emissions from boats and ships [1]. Many studies show that employing hybrid-electric propulsion in marine vessels can be a feasible solution for reducing emissions and fuel consumption [2,3]. High level of maneuverability, reduction of fuel consummation, improving efficiency, reduction in noise and vibration, and compliance with new environmental regulations are some of the main motivation behind the development of hybrid-electric propulsion systems for marine vessels [4].…”

This paper evaluates the maximum torque capability of a hybrid excited synchronous machine in comparison with a conventional PM synchronous motor. The main focus of the paper is on the study of the effect of DC excitation magnetic flux on the saturation of the stator teeth, which limits the torque production capability of the hybrid machine. Magnetostatic and transient analyses are carried out for both motors. As expected the hybrid motor air gap flux controllability comes at the expense of reducing its torque density. The torque density reduction penalty is quantified and some hidden limitations and challenges of designing such a hybrid motor are revealed based on an in-depth analysis of the flux distribution within the machine.

“…In addition to the propulsion loads of a ship, there exist other loads such as the hotel loads and reefer loads. An example of a complete load profile of a ship [14] that takes into account all the different types of loads [14] is the Post Panamax container carrier when at sea for 75% of the time in a year is shown in Figure 3 and Table 2. Note that ME refers to Main Engine while CSR is defined as the Continuous Service Rating, which is taken to be 90% of the maximum continuous power rating.…”

“…LV equipment such as those used for lighting and other hotel loads are non-essential loads and are usually connected via the LV switchboard. A typical schematic for a shipboard radial power system of a ship employing electric propulsion as explained in [14] is shown in Figure 1a. Modern shipboard power systems are moving towards the Zonal Electrical Distribution System (ZEDS).…”

Effect of Load Changes on Hybrid Shipboard Power Systems and Energy Storage as a Potential Solution: A Review

More electric technologies (METs) play an important role in meeting ever-growing demands for energy efficiency and emission reduction in the maritime transportation sector. As a result, ships with electrical power transmission are becoming popular compared to traditional mechanical power transmission based ships. Hybrid electric propulsion is an intermediate step in this trend where both mechanical and electrical propulsion technologies are combined to get the benefits of both technologies. In this arrangement, not only the propulsion loads but also non-propulsion loads are connected to a common electrical power bus that could lead to serious power quality issues due to disturbances such as large load changes. This paper presents a comprehensive review on energy storage-based solutions that have been proposed to reduce their effects. The important aspects of existing as well as emerging energy storage control techniques and challenges in reducing transient effects in hybrid shipboard power systems with the use of energy storage are discussed in the paper.
