Increasing wind turbine efficiency

Renewable energy technology considers as alternative solutions to reduce the carbon emission and global warming potential in the world. In the renewable energy, wind and solar cell power are the best techniques to produce the power. But the efficiency of the systems is low compared to the conventional method. The purpose of this research is to develop a smart model of a wind blade which enabling the blade to change its area according to wind velocity in order to achieve best angle of attack of each, this concept is against increasing wind size to increase wind efficiency, however, other barriers of maintenance and the dramatically increases of cost are apparent when we mention increasing wind turbine size. The smart blade could be the alternative solution of the size increasing. Two different smart blade models have been analyzed at different wind velocity and best angle of attack discovered where efficiency is perfect.
