MPPT Control of Hydrokinetic Energy Conversion System

Hydropower is one of the best sources of power as flowing water is available in a sufficient amount in nature. The Hydrokinetic Energy Conversion System (HECS) uses kinetic energy of the running water to rotate the turbine blades and generate power. This energy conversion system has been designed, and the output power of this system is effectively controlled with the Perturbed and Observe technique of Maximum Power Point Tracking (MPPT) control. A Permanent Magnet Synchronous Machine (PMSM) is coupled with the turbine to generate electricity. The generator's output power is then fed to a three-phase uncontrolled rectifier to convert it to DC from AC. A boost converter is utilized to control this DC power by controlling duty ratio. The system model has been designed and simulated. The validation of MPPT control strategy has been done with the help of simulated result of HECS.
