Abstract—The oceans of the earth offer vast amounts of renewable energy. Technologies to harness the power of the seas are at an early stage of development. Tidal energy is receiving worldwide attention, as it is a renewable energy that presents high energy density, high predictability, and low environmental impact. This paper presents a theoretical and analysis study of turbines to improve tidal energy systems. The parameter for the structure component that is, the turbine blade is the main component was taken by reading from previous research papers related to the tidal turbine system. In this study, the parameter for structure and hydrodynamic performance, theoretical analysis, and the data of Power Coefficient, Cp is obtained. The maximum Power Coefficient, Cp value for Langkawi, is 0.28 with Tip Speed Ratio, λ 6.26 and 6.43, 0.284 both for Malacca Strait, and Kuala Terengganu with Tip Speed Ratio λ 6.25, 6.31, and 6.41 Cp value with 6.56, 5.94 λ value. The hydrodynamic performance in this research depends on the Power Coefficient, Cp, and Tip Speed Ratio, λ. The most optimum Tip Speed Ratio, λ is the range between 5 and 6. The power output is 0.108 MW can supply electricity to 0.83 houses a year.

Keywords—vortex-induced vibrations, numerical simulation, reduced velocity
