Hybrid current turbine and solar cell renewable energy device

Abstract

Renewable energy has always grabbed attention to innovation and as a means of reducing the use of fossil fuel in generating energy. One of the sources yet firm establishes to explore is ocean energy. Due to the low current speeds in Malaysia, hybrid renewable energy has been proposed to support the amount of power on generating energy from the ocean. Thus, the purpose of this study is to evaluate the effectiveness of a Low-Speed Vertical Axis Current Turbine (LSVACT) with solar cell photovoltaic (PV) in providing minimum power demands in Malaysia. The Low-Speed Vertical Axis Current Turbine (LSVACT) is a small-scale hydro turbine power that is suitable for low-speed current flow as its vertical axis design allows it to easily absorb power from any incoming water direction. However, the ideal current speed which is at 2.25 m/s can be suitable/effective for a few potential places in Malaysia. This study evaluated the potential current speed in one of the potential areas in Malaysia using Delft-3D simulation. For solar energy, evaluated by record day-to-day power output by the solar panel. The results of the simulation were then converted into power generation, together with the results of Solar Panels and batteries storage capacity. Two LSVACTs with four Solar Panels and 1250 Ah were suggested to generate a power during Inter Monsoon Period while two LSVACTs with six Solar Panels and 1500 Ah were suggested to generate the power during the Monsoon Period. The design system can generate and supply enough energy for a system cycle.
