“…The propulsion loads on vessels follow the propeller's law, with the propeller torque being approximately proportional to the square of the rotational speed of the propeller [60]. For this type of load, the technical specifications in [61] recommend the use of DC motors working with armature control; this includes the separately excited DC motor currently implemented in Project 7. Also, DC motor equivalent circuits are used in the literature to model core aspects of AC motors [56].…”

“…Considering the difficulties to find the electrical motor parameters in the literature, a sizing approach was adopted for parameter identification to improve the efficiency of the machine. The work by [61] presents a method for parameter identification for different electric motor types based on desired operation conditions. Given information about the desired operation, all the other electrical parameters of the motor can be determined by an algorithm.…”

Climate concerns, regulations, and fuel costs are driving higher efficiency designs in the shipping industry. Research works suggest that hybrid power systems can be a viable option to reduce fuel consumption and emissions. However, more studies are required to analyze its net gains in different applications. In this work, numerical simulations of power systems are performed in a causal approach, including a non-hybrid or base case and a hybrid case, for a diesel-electric Platform Supply Vessel (PSV). Dynamical and static models are considered for the power sources, namely, diesel generator sets (gensets) and a lithium-ion battery pack connected through an AC electrical network. For the Energy Management System (EMS) of the base case, an optimization of gensets is performed, and for the hybrid case, a rulebased control combined with an optimization of the generators is considered. The analysis shows, for the case study, that the greatest potential for battery usage is achieved in near port operations. Cleaner operations were allowed in these regions due to the increase in energy efficiency and the disconnection of generators. A fuel consumption reduction of 6.35% and CO 2 emission reductions of 5.81% were achieved for the complete mission. Also, an increase of 1.73% in the overall energy efficiency was accomplished.

Sensitivity analysis is useful for parameter estimation and decision-making processes. It guides researchers in which input is more effective for controlling an output and which output provides more information to estimate a system parameter. This study is concerned with the sensitivities of the measurable states of electric motors to the model parameters and load torque. Its contribution is investigating the sensitivities’ dependencies on design requirements. It has been revealed that some design requirements such as rated voltage, power, and speed have no effect on most sensitivities to the motor parameters. A similar study on transformers is also included with similar results. The results evoke some optimization choices about adjusting the sensitivities since the search space dimension is reduced. They also yield some educational benefits. Since such a theoretical study requires precise measurements or disturbance-free information, experimental work could not be very useful. Therefore, either mathematical model analysis or simulations have been used to calculate the sensitivities. For the same reason, design requirements are considered from the algorithms determining the model parameters of electric machinery according to desired operating conditions for simulation purposes. Dependencies have been found analytically for dc motors but numerically for ac motors, and transformers.
