The use of wind energy, as a substitute for fossil energy, increase to generate electricity. The utilization of wind energy in rural areas that is not connected to the grid is very beneficial to the community. System stand-alone wind turbines small scale with a permanent magnet synchronous generator (PMSG) is very suitable for rural areas. To optimize the output power which is generated by wind turbine, controller is required to extract the maximum power. Fuzzy controller has been developed to produce a power output without using a mechanical sensor. Fuzzy controller controls the duty cycle of boost converter to obtain optimum generator speed and maximum power output of wind turbine system. To maintain the DC link voltage, bidirectional converter controllers have been used through the setting charging and discharging of the battery. Based on simulation results, the fuzzy controller has good performance to extract the optimum power. Fuzzy controller can maintain power coefficient on the optimal value despite a change in the wind. © 2006-2017 Asian Research Publishing Network (ARPN). All rights reserved.
