Conventional maximum power point tracking (MPPT) methods used for stand-alone wind power generation systems (SWPGS) have low reliability, and thus a passive solution for MPPT was presented. Using a special structural design, it is possible to create a new generator system where the input power vs. rotor speed curve naturally fits to the wind turbine maximum power point (MPP) curve. This characteristic allows the proposed system to automatically realize MPPT without the use of any algorithm or electrical control device, thereby resulting in high reliability. The principle of the passive MPPT method was analyzed, and the mathematical model of the proposed system was established. The results show that the proposed system adopting the passive MPPT method can realize the passive MPPT, and its dynamic performance of MPPT is better than that of the conventional system using hill-climbing searching method.
