Abstract This paper proposes a novel optimal current given OCG maximum power point tracking MPPT control strategy based on the theory of power feedback and hill climb searching HCS for a permanent magnet direct drive wind energy conversion system WECS. The presented strategy not only has the advantages of not needing the wind speed and wind turbine characteristics of the traditional HCS method, but it also improves the stability and accuracy of MPPT by estimating the exact loss torque. The OCG MPPT control strategy is first carried out by simulation, then an experimental platform based on the dSPACE1103 controller is built and a 5.5 kW permanent magnet synchronous generator PMSG is tested. Furthermore, the proposed method is compared experimentally with the traditional optimum tip speed ratio TSR MPPT control. The experiments verify the effectiveness of the proposed OCG MPPT strategy and demonstrate its better performance than the traditional TSR MPPT control. View Full-Text
