In this particular study, ocean current and wind
energy options are employed to produce electricity. Here, current turbines and
wind turbines, which have the same work
principle, are utilized accordingly. In addition, a pumped hydro storage
subsystem is integrated into and utilized to provide better sustainability.
During night times electricity demand is less or minimum, a particular amount
of produced electricity is provided to pump water to the reservoir at the 50 m.
Finally, when electricity demand is high, the stored
water from the reservoir is utilized to
produce electricity by a hydropower turbine. Wind and current velocities of Bosphorus,
Istanbul is considered in the calculations. Some parametric studies are
conducted to evaluate the system with different variables, including the wind
and ocean velocities, turbine blade
radius and density of seawater. By designing this kind of system, electricity generation
can be provided. 8.8 MW and 12.6 MW electricity power are obtained by 20
wind and 20 current turbines. At night, a
flowrate of 17.69 kg/s water is pumped to the
reservoir. In the day time, a total of 6.9 MW electricity is obtained by the hydropower
turbine.
