“…Two percent of the world's coastal waters have wave power densities that are great enough for extracting wave energy that equates to 480 GW of power output for 4200TW h/yr of electricity generation [8]. The global theoretical energy from waves corresponds to 8x106 TW h/yr, which is about 100 times the total hydroelectric generation of the whole planet [9]. To produce this energy using fossil fuels, it would result in an emission of 2 million tonnes of CO2 [10].…”

The ocean offers vast opportunities for unprecedented energy harvesting where most studies had concentrated on large scale energy harvesting from the ocean waves. However, there were minimal studies on low-scale energy harvesting. This study focuses on ambient, low-scale energy harvesting which theoretically can be used to power low energy consumption electrical appliances. The inherent characteristic of piezoelectric materials which can convert mechanical energy to electrical energy has created an alternative to generate energy from renewable sources including ocean waves. Initially, this study started with preliminary work which consisted of the development and testing of a lab scale piezoelectric energy harvester (PEH-1) which was tested along the beach area of Kuala Nerus, east coast of Malaysia. Results from PEH-1 had shown that the high tide produced more power level compared to low tide experiments. The findings from the first phase of this study served as a foundation study towards the development of an upscaled version of the PEH-1 in relation of mechanical and electronics, which was termed as PEH-2. Testing for PEH-2 was conducted in the coastal area of Pulau Bidong Laut, Kuala Nerus. Results from the second part of the study had shown that approximately almost 80% of the power harvested correlated linearly with wind speed, however after reaching 0.7W the peak dips down which was probably due to the instability of PEH-2 to be used in harsh open seas environment. This study had shown the feasibility of utilizing piezoelectric material to harvest low-scale power, however, several in-house modifications needed to be made for it to be fully functionable.

“…It is anticipated that a significant portion of the future energy mix will comprise renewable sources of energy, which can play an important role given their enormous potential, particularly wave and tidal stream generation [1]. Similarities between offshore wind and tidal stream turbines include the usage of electric machinery, system structure, and control strategies [2]. It has been found that, globally, sources of marine energy are extensive when compared to other renewable energy sources such as wind, solar, geothermal, etc.…”

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.
