Fuzzy logic based wind energy conversion system with Solid oxide fuel cell

In recent years the Double-Fed Induction Generator (DFIG) gaining more popular due to their variable speed and variable pitch control. A dynamic Solid oxide fuel cell (SOFC) is integrated with Double fed Induction Generator (DFIG), due to their fluctuating nature of wind energy. This paper presents a simulation of SOFC fuel cell integrated with a doubly fed induction generator to maintain grid voltage constant 440 V and 50 Hz. Existing literature used PI controller based vector control technique for the control of DFIG. In this work, fuzzy logic controller is proposed to decrease total harmonic distortion in grid current. The performance of the system for sudden load changes with PI control and proposed control technique has been obtained and compared, by using MATLAB SIMULINK.
