“…In recent years, numerous studies of the hydrodynamic aspects (Mycek et al 2014;Frost et al 2015;Blackmore et al 2016) and the design of specific generators for the marine environment (Benelghali et al 2012;Seck et al 2018;Chen et al 2019) have been conducted. Meanwhile, other studies focus on the electronic part of power (Pham et al 2017;Einrí et al 2019;Omkar et al 2019;Qian et al 2019).…”

This paper presents a contribution related to the control of nonlinear variable-speed marine current turbine (MCT) without pitch operating below the rated marine current speed. Given that the operation of the MCT can be divided into several operating zones on the basis of the marine current speed, the system control objectives are different for each zone. To deal with this issue, we develop a new control approach based on a linear quadratic regulator with variable generator torque. Our proposed approach enables the optimization of the rotational speed of the turbine, which maximizes the power extracted by the MCT and minimizes the transient loads on the drivetrain. The novelty of our study is the use of a real profile of marine current speed from the northern coasts of Morocco. The simulation results obtained using MATLAB Simulink indicate the effectiveness and robustness of the proposed control approach on the electrical and mechanical parameters with the variations of marine current speed.

“…The tidal kite is a novel technology, which uses wing carrying and pushes a turbine in an "8" shaped trajectory, sweeping a large area with a relative speed of more than the local current speed [133][134][135]. A review of the tidal current technology is presented in [136].…”

This study, firstly, provides an up-to-date global review of the potential, technologies, prototypes, installed capacities, and projects related to ocean renewable energy including wave, tidal, and thermal, and salinity gradient sources. Secondly, as a case study, we present a preliminary assessment of the wave, ocean current, and thermal gradient sources along the Brazilian coastline. The global status of the technological maturity of the projects, their different stages of development, and the current global installed capacity for different sources indicate the most promising technologies considering the trend of global interest. In Brazil, despite the extensive coastline and the fact that almost 82% of the Brazilian electricity matrix is renewable, ocean renewable energy resources are still unexplored. The results, using oceanographic fields produced by numerical models, show the significant potential of ocean thermal and wave energy sources in the northern and southern regions of the Brazilian coast, which could contribute as complementary supply sources in the national electricity matrix.

“…In order to addresses the aforementioned issues, during the last decades extensive control theories have been investigated. A detailed review on the control strategies developed for PMSG based tidal energy conversion system is presented in [5]. For maximum power harnessing, a sliding mode control (SMC) strategy has been proposed in [6].…”

Intelligent Energy-Based Modified Super Twisting Algorithm and Factional Order PID Control for Performance Improvement of PMSG Dedicated to Tidal Power System

The majority of marine current conversion technologies are based on permanent magnet synchronous generators (PMSG) due to its numerous advantages such as high-power density, low cost, and favorable electricity production. However, nonlinear properties of the generator and parameter uncertainties, makes the controller design more than a simple challenge. This paper proposes a new adaptive passivity-based (PB) modified super twisting algorithm (PBSTA) for control performance improvement (low tracing errors, fast convergence response, robustness) of a PMSG based marine current energy conversion system under swell effect and parameter uncertainties. The proposed approach combines a new PB current control (PBCC) with a new adaptive modified super twisting algorithm through a fuzzy logic supervisor. A new adaptive fractional order PID (FO-PID) controller is introduced to design the desired dynamics of the system. The main contributions and motivation of this work include the extraction of maximum power from the tidal current, integrating it to the grid and making the closed loop system passive. This is possible by reshaping system energy and introducing a damping term that compensates the nonlinear terms by a damped way and not by cancellation. Two steps are needed to design the proposed controller: the first step includes the derivation of reference current based on the reference torque using adaptive FO-PID. In the second step, the overall control law is computed by the proposed PBSTA. The exponential stability and error convergence of the proposed controller are analytically proven. The developed controller is tested under parameter variations and it is compared to benchmark nonlinear control methods such as sliding mode. Extensive investigation under MATLAB/Simulink, demonstrates clearly that the proposed technique provides higher efficiency and robustness over the benchmark nonlinear control methods.
