The application of wind turbines in a wind farm requires a voltage control system to cope with changes in wind velocity. The purpose of this research is to stabilize the output voltage of the wind farm using supervisory-Fuzzy Logic Control (Supervisory-FLC). This control consists of supervisory level and Fuzzy Logic Control (FLC). The supervisory level functions to provide duty cycle adjustment for an original duty cycle which is obtained from the characterization results, while FLC has a task to stabilize the output voltage. FLC is designed using two inputs-namely errors and delta errors-and one output, i.e. duty cycle. In order to know the performance of the proposed control, simulation study was conducted using two wind turbines as wind farm, and a multi-input buck converter as final control element. From simulation results it is proven that Supervisory-FLC has superior performance compared to FLC with the maximum error of 0.138 Volts and the integral time absolute error generated is 235.158.
