This paper shows that the optimization of the electrical energy production from a tidal turbine is dependent on the constraints of the site. The Raz Blanchard area is presented as an example. The proposed turbine is based on the 0.55MW Doubly Feed Induction Generator (DFIG) connected to a turbine with a radius of 10m. The proposed model is implemented in Matlab/Simulink software for system simulations. The simulations are done using the tidal current magnitude calculated with a hydrodynamic model. The obtained results are presented and analyzed.
