Vertical Axis Wind Turbine is one of the most widely developed Renewable Energy. Many experiments and research are conducted to obtain maximum power efficiency. To get the maximum energy conversion efficiency required TSR (Tip Speed Ratio) is constant. To have the efficiency controller to change the Angle of Attack is required to maintain maximum efficiency at any wind speed. The method is applying controlled blades (aileron), the blades represent the value of Angle of Attack. In accordance with the changing of wind speed. In the VAWT Darrieus TSR reference value of 6, this value becomes the reference to obtain maximum efficiency against changes of wind speed. PID method is used to control the blades to form an Angle of Attack corresponding to the dynamic changes in wind speed. So that the VAWT speed is used as feedback into control. The shape of the blade affects the efficiency of the resulting spin, therefore the most efficient blade of the blades is the thin airfoil family in order to obtain the maximum flow of wind to rotate the generator. From the simulation done by using VAWT, it can be shown that the power efficiency obtained up to 28% in any wind speed.
