The Cycloidal Vertical Axis Wind Turbine is based on a self-adjustable pitch concept that automatically pitches the blade to improve the azimuthal load distribution and energy conversion. In nominal operating point, theoretical and CFD analysis have demonstrated that a cycloidal turbine can be more efficient than classical VAWTs, being able to produce more energy at low and intermediate Tip-Speed-Ratios. This innovative cycloidal wind turbine can also eliminate some problems of self-starting in VAWTs. In the following paper we propose the introduction of a new generation of wind energy converter system. We will show, trough the use of numerical tools, that the proposed system is more efficient than classical VAWTs.
