Abstract

This paper proposes the speed sensorless fuzzy MPPT control of grid-connected PMSG for wind power generation. The proposed fuzzy MPPT control is simple since it does not need any knowledge of wind turbine characteristics and speed sensor. Based on small wind power generation, the boost chopper is used to implement the proposed fuzzy MPPT control. There is a specific value of duty cycle which yields maximum power at particular wind speed. To find this duty cycle value, the fuzzy MPPT control only needs the information of power and duty cycle. The proposed fuzzy MPPT control will be verified through PSIM simulation at wind step and fluctuating wind speed condition. Moreover the proposed fuzzy MPPT control will be compared with the conventional fuzzy MPPT control, whereas the speed sensor is still used.
