The low speed toothed doubly salient permanent-magnet (TDSPM) machine is an interesting candidate motor for electric ship applications because, of its high torque output, maintenance-free operation and flexible working modes, which gives the opportunity to increase system’s reliability, and decrease the system size, weight and noise which are key features for naval applications. However, particularly in the 3-phase configuration, the stator and rotor saliency of these machines leads to a high level of torque ripple. To overcome these drawbacks, the use of polyphase machines (with a number of phases greater than three) can be a relevant solution. In this paper, an optimal design of two kind of novel 4-phase motors is performed in order to fulfil the specifications of a high power naval ship propulsion. The designs aim to maximize the torque to mass ratio. The motors’ performances are directly linked to their structural parameters, so, the impact of the coil number in terms of mean torque, torque ripple, energy ratio values, and efficiency is also presented and analysed. The design of these two electromagnetic structures, as well as the determination of their electromagnetic performances, are carried out using a particle swarm optimization algorithm (PSO) with taking into account thermal constraint. The performance of the proposed machine in terms of mean torque, torque ripple, energy ratio, and efficiency values is presented and analysed. The results obtained reveal that the TDSPM machines with four poles/phase are good candidates to meet the requirements of high power direct-drive ship propulsion system.

This paper focuses on the formulation of state–space representations of radiation forces for marine structures using Hankel Singular Value Decomposition (HSVD), a method used to obtain a state–space realization from a Hankel matrix, with the classical definition of the kernel function and its new definition given in this paper. The first part shows the influence of a term commonly neglected and the resulting improvement by taking this term into account. The second part will focus on the feedthrough matrix to understand why some models have none and why some others, such as HSVD, have one. An exact definition of the kernel function will be given underlying its discontinuity and its causality. This study also shows the interest of extrapolating hydrodynamic coefficients before approaching radiation forces by a state–space model.

Based on a multidisciplinary and configurable modeling approach, this work deals with the optimal choice and the design of a hybrid propulsion with the associated power management strategy to replace a conventional propulsion in a low tonnage river ferry operating on short cycles, with the aim of reducing its environmental impact and the costs over its entire lifetime. The considered ferry is used for the transport of people and vehicles crossing the Seine river, with an installed propulsive power of 330 KW. The operating cycle of the ferry and the energy consumption of its classical propulsion have been determined experimentally and then used as references in simulations for validation and comparison purposes. Two hybrid structures involving the use of batteries and supercapacitors were proposed and compared. It is shown that the hybridization leads to a substantial reduction in CO2 emissions. The supercapacitor- and battery-based hybrid structures lead respectively to 18% and 29.7% CO2 reduction compared to classical propulsion, representing, respectively, about 382 and 626 tons of CO2 reduction over 20 years of operation. Despite the fact that the use of batteries leads to a more significant reduction in CO2 emissions, the solution using supercapacitors is chosen following a technical-economic study over 20 years of operation.

Wind turbine (WT) technology becomes more and more important due to the serious environmental and energy issues. The toothed poles outer rotor doubly salient permanent magnet (DSPM) generator with simple and durable design, high torque and high-power density has a great prospect in wind turbines application. The large diameter makes the construction of such a machine more convenient due to the installation of the turbine blades directly to the outer rotor generator surface. Nevertheless, the size of the generator must be increased to provide larger output power. This increases the generator’s mass. Thus, larger massive DSPM generators are undesirable in wind turbine design. In this paper, an optimization design procedure of the outer rotor doubly salient permanent magnet generator ORDSPMG is proposed for 10 kW WT application. The reduction of the generator weight is demonstrated and proofed. The considered machine version is characterized by having the same effective axial length and output torque imposed by the specifications relative to the 10 kW direct drive WT. An optimization procedure using a fast and effective method, namely the symbiotic organism search (SOS) algorithm coupled to a parametric two dimensional finite elements analysis (2D-FEA), is employed to optimize the machine parameters. The main parameters affecting the generator design are also analyzed. The results obtained reveal that the proposed generator topology presents low weight and thus high torque density among other satisfactory characteristics.

In this paper original analytical models to determine the electromagnetic performances of segmented permanent magnet synchronous machines (with removed active parts in the stator or the rotor) are presented. These models are adapted to PMSM with large air gap width, large diameter, a high number of poles and large angular gaps. This method based on analytical approach is validated by comparizon with a 2D Finite Element calculation (Altair FluxTM 2D) for the specifications of a large diameter, low speed tidal high power current turbine generator. The presented method allows fast and accurate evaluation of the performances of this kind of particular machine and can be used in a systematic design process.

Refined assessments of the available tidal stream energy resource are required to optimize turbines design and guarantee successful implementations and operations of devices in the marine environment. Investigations primary focused on identifying areas with maximum current speeds. However, further information may be reached by exhibiting (i) resource temporal variability, (ii) superimposed effects of meteo-oceanographic conditions (including especially wind-generated surface-gravity waves), and (iii) potential environmental impacts of operating turbines at the regional (e.g., changes in sediment transport and surrounding seabed features, effects on marine water quality, etc.) and local (wake-wake interactions and energy output) scales. These aspects are here investigated by reviewing a series of research studies dedicated to the Fromveur Strait off western Brittany, a region with strong potential for tidal array development along the coast of France. Particular attention is dedicated to the exploitation of combined in-situ and remote-sensing observations and numerical simulations. Beyond a site specific characterization of the tidal stream energy resource, this review promotes a series of original approaches and analysis methods for turbines optimization, thus complementing technical specifications to secure the key steps of a tidal energy project and promote the growth of a reliable tidal stream energy exploitation.

The offshore wind resource has huge energy potential. However, wind turbine floating structures have to withstand harsh conditions. Strong wind and wave effects combine to generate vibrations, fatigue, and heavy loads on the structure and other elements of the wind turbine. These structural problems increase maintenance requirements and risk of failure, while reducing availability and energy production. Another challenge for wind energy is to reduce production costs in order to be competitive with other alternatives. From the control point of view, the objective of lowering costs can be achieved by operating the turbine close to its optimum point of operation under partial load, guaranteeing reliability by reducing structural loads and regulating the power generated in strong wind regimes. In this typical and challenging context, this paper proposes a critical state-of-the-art review, discussing challenges and trends on floating offshore wind turbines control.

This paper investigates modeling, control and power management aspects of tidal energy conversion system (TECS) with an energy storage system (ESS) unit connected to an islanded grid. The model presented in this work takes into account entire conversion system including machine, AC-DC converter, DC-AC converter, DC-DC converter and supercapacitor-based energy storage system. A dynamical modeling of the complete TECS is achieved using the graphical formalism Energetic Macroscopic Representation (EMR) and inversion-based rules are used for the control development. In addition to the modeling and control of TECS, a simple algorithm to manage the power flows between the system components is proposed. The proposed algorithm ensures the slope limitation of the active power supplied to the grid and maintains the state of charge of the supercapacitor at acceptable levels. The performances of the overall grid-connected TECS with ESS are evaluated based on tidal current data from the Ushant Island.

This paper deals with a design methodology of permanent magnets (PM) generators used for fixed-pitch tidal turbines in a marine renewable energy context. In the case of underwater turbines, fixed-pitch tidal turbines could be very attractive and interesting to reduce maintenance operation by avoiding using such a complex electromechanical system for blade- pitching. In this technological case, one of the main control challenges is to ensure power limitation at high tidal current velocities. This control mode can be achieved using the generator flux-weakening. In this context, this paper proposes an original and systemic design methodology to optimize the generator design taking into account the tidal turbine power limitation for high tidal currents velocities.

To smooth the power fluctuations induced by marine current speed and to satisfy standard grid constraints, the tidal current turbine system should be combined with an energy storage unit (ESU). However, adding ESU into the existing system results in a complex structure of the entire electromechanical conversion chain that needs appropriate tools for system modeling and control development. For that purpose, this paper focuses on the use of a graphical tool based on energetic macroscopic representation (EMR) in order to model the system and design control schemes of a grid-connected tidal current turbine system including a supercapacitor-based energy storage. The transcription of EMR to Matlab/Simulink environment through the available EMR library allows a simple development of overall system control using the inversion-based rules. Simulation results, obtained from the developed simulator, are shown and discussed.

This paper presents a new analytical model to determine the cogging torque of stator-segmented permanent magnet machines (with angular air gaps, i.e. flux barriers, located in the stator). Basically, if the saturation is not considered, the cogging torque can be seen as the sum of two independent contributions: the first contribution results from the cogging torque related to an equivalent slotless machine with a single gap, the second resulting from an equivalent non-segmented slotted machine. For the specifications of a marine current turbine generator, this analytical approach is evaluated and compared with a numerical 2D Finite Element Analysis (Flux™ 2D by Altair).

This paper deals with the design and analysis of a virtual synchronous generator (VSG) control strategy applied to a renewable-based system devoted to energy production in a stand-alone microgrid context. The studied hybrid energy production system consists of renewable-based energy production systems, a diesel power plant (DPP), and an energy storage system (ESS). The first part of the study will deal with the design of a single renewable energy source controlled using the VSG control strategy. In the second part, multiple renewable energy sources, similar to the one presented in the first part, will be connected in parallel to form a renewable farm. Finally, in a third part, the studied renewable farm will be integrated in a full hybrid system. In each part of the proposed study, the system power output will be evaluated and the voltage and frequency variations will be carefully analysed.

Estimating the energy potential of tidal stream site is a key feature for tidal energy system deployment. This paper aims to compare two methods of prediction of tidal current velocities. The first one is based on the use of a fully three-dimensional (3D) numerical approach. However, while being accurate, the numerical model is highly time-consuming. The second method is based on a linear approximation of the tidal current, which only requires preliminary knowledge of local current velocities time series during two typical tidal cycles. This second method allows a very quick evaluation of the tidal stream resource during a long time period. The proposed comparison is done in three different locations of a high potential tidal energy site in west of France. It is carried out in terms of current velocity and energy harnessing for several turbines technology options (with and without yaw). The achieved results show that the linear approximation gives satisfactory evaluation of the tidal stream potential and can be a very interesting tool for preliminary site evaluation and first technology options selection. However, the fully 3D numerical model can obviously be very useful in more advanced steps of a project.

Assessing the reliability of power electronic converter systems is an essential task. New generations of components and topologies will be deployed in industrial segments such as renewable energy and electric vehicles. Although the lack of experience feedback, the reliability of those converter systems may be estimated by assessing stress profile and using physics-of-failure models. This method is used in the assessment of a wind turbine converter reliability including the effects of the uncertainty in the lifetime model parameters. By using Monte Carlo method, this paper exhibits the strong impact onto the reliability function of the input parameters although their weak scattering.

In this paper, an optimal design of unconventional electrical motor called Multiphase Doubly Salient Permanent Magnet Motors is performed in order to fulfil the specifications of a high power naval propulsion motor. The design aims to maximize torque to mass ratio. Particle swarm optimization method is used for the design of this kind of doubly salient permanent magnet machines with 3, 4 and 5 phases. All the studied machines have the same volume and use the same active part material characteristics (magnets, iron and copper). The electromagnetic performances and geometrical main data of the studied machines are analyzed and compared with those of a reference 3-phase conventional permanent magnet synchronous machine designed for ship propulsion. For the same constraints, the proposed machines exhibit a 90% lower permanent magnet volume and are colder than the compared machine. So, the proposed machines appear suitable for this kind of application.

In this work, the possibility to recover energy during braking operations in a low tonnage ship is studied. A simple full electric propulsion chain is considered. The models of the different elements of the propulsion chain are described and then integrated for a dynamic simulation on a Matlab/Simulink code. This model includes a 4-quadrant model for the propeller which allows taking into account energy harnessing. A case study is considered based on the specifications of a river shuttle. Several control strategies of the electrical propulsion motor during braking are studied. Results highlight the advantages of applying a Maximum Power Point Tracking (MPPT) strategy (like in a wind or tidal turbine) which leads to a considerable increase of the recovered energy.

This paper addresses the estimation of the 3D air gap field for Ironless Rotor Double Stator axial flux Permanent Magnet machines: the described method is based on a coulombian representation of the Permanent Magnets and the mirror theory. This approach can take into account the significant 3D effects that can occur in machine with very large air gap (that might be used in wind or tidal energy harnessing). For validation purpose, a laboratory prototype has been manufactured, the machine being characterized by the possibility of changing the air gap values. For several air gap values, experimental and calculated no load voltages are in good agreement, thus showing the ability of the focused calculation method to evaluate the performances of these particular machines.
