“…The block diagram presents a grid-connected tidal energy generation system, as shown in Figure 2. The AC output of the PMSG was rectified, and the DC-link voltage was then adjusted to obtain constant voltage by means of a PI controller, and the constant DC-link voltage was inverted to obtain the AC voltage recommended [24,25]. The LCL filter model is shown in Figure 2, where L 1 is the inverter-side inductor, L 2 is the grid-side inductor, ρ is a capacitor with a series R f damping resistor, R 1 and R 2 are inductor resistances, and voltages vi and vg are the input and output (inverter voltage and output system voltage).…”

Nowadays, integrating renewable energy sources, such as tidal power, into the existing power grids of turbines is crucial for sustainable energy generation. However, tidal turbine energy transforms the potential energy of moving water into electrical energy. When both nonlinear load and dynamic load harmonics are present, the tide speed variance causes serious power quality issues such as low power factor, unstable voltage, harmonic distortions, frequency fluctuations, and voltage sags. The integration of an LCL-filter-based connection scheme can address these challenges by improving power quality and the overall performance of the tidal current turbine grid system. This study shifts LCL filter research from its conventional wind energy emphasis to the emerging field of tidal stream generation systems. The LCL filter analysed in this paper is modelled to exhibit adequate mechanical, electrical, and hydrodynamic characteristics. This model accounts for tidal current variations, turbine speed control, and power extraction dynamics. The LCL filter is evaluated for its effectiveness in reducing harmonic distortions, voltage fluctuations, and reactive power fluctuations. This system is composed of a 1.5 MW/C, a 1.2 MW three-level inverter with a nominal voltage of 600 V, and an inductance (LCL) filter. The results show that the inverter produces a harmonic distortion of less than 0.5%, which demonstrates the effectiveness of the filter in improving total harmonic distortion, reactive power consumption, and voltage control.

“…In the work in [64], numerical models were developed to provide all the necessary technical information regarding resource exploitation and their effects including inconsistencies in the simulation model of the results of tidal power plants, program operations and others. In this work, different models were presented for the gradual and systematic introduction of spatial dimensions in resource forecasting applications.…”
