碩士 === 中原大學 === 電機工程研究所 === 102 === ABSTRACT The purpose of this thesis is to design a wind power hybrid system, in which it can connect different green power. The wind power generation output is boosted a by a high step-up converter to hybrid modular system. The hybrid system is composed of a master converter and sever slaver converters, where the master converter stabilizes the output DC voltage and the slaver modules perform the maximum power point tracking (MPPT). In order to achieve the wind turbine maximum power point and stabilize the output voltage, we propose a fractional-order PID controller to control output voltage and current. The voltage and current controllers are simulated by Matlab software to show the control responses. In experiments, the FOPID controller is constructed by an analog circuit. The low-cost MCU HT56R22 is applied to realize the controller chip. Finally, the wind power maximum power point tracking is verified by the experiments.
