Design Considerations of a Hybrid Piezoelectric-Electromagnetic Tuning System for Vortex Induced Vibration Bladeless Turbines: Morocco Case Study

New technologies are being investigated to increase the efficiency of Vortex Induced Vibrations (VIV) wind generators. The hybridized VIV bladeless turbine is a new system that combines electromagnetic induction and piezoelectric materials to efficiently harvest wind energy. This hybridized system combines the effectiveness of both power generation methods which yields a higher conversion efficiency. However, such systems are only efficient when the wind speed is tuned to their resonant frequency. This paper presents the design of a tuning system for a hybrid piezoelectric-electromagnetic energy harvester. It also investigates the feasibility of this new scheme and analyses its implementation into VIV classical bladeless turbines. Additionally, this paper assesses the efficiency factor and cost-effectiveness of the suggested system. Furthermore, a draft cost study of a case study implementation in Morocco is presented.
