Tidal turbine has a relatively high potential in extracting the
tidal current energy in terms of the cost, environmental impact
and overall reliability [72]. Moreover, optimisation and maximising of the power output has been well assessed and formulated at
the current stage of development, such as the numbers of
turbines should be installed, a practical way in estimating the
power extraction and so on [66,68,73], even though extracting the energy under difficult situation, such as lower current speed [67].
This would increase and strengthen the confidence level of the
interested parties who are going to extract ocean renewable
energy using tidal turbine.
