The need of making wind farms more efficient demands the assessments of new concepts, bringing these to the demonstration level. This chapter targets more specifically floating wind farms of Vertical Axis Wind Turbines (VAWTs). These wind farms are specifically suitable for harvesting wind energy at deep-sea waters, the next frontier of offshore wind farms. The chapter describes the new concept of making clusters of three VAWTs to increase the overall average power output of wind farms. The cluster topology concept takes advantage of the acceleration of the flow observed through the gap between closely spaced turbines (“funneling” effect). The concept also involves the adoption of active blade pitch control strategies to both generate wakes deflections, optimizing the “funneling” effect (collective and cyclic control), and improve structural fatigue life using the higher-harmonic control technique for mitigating blade high dynamic response due to the aeroelastic effects.
