Abstract: To achieve superior harmonic reduction using hybrid energy generation high power devices interfaces, an advanced fuzzy current and voltage controlled technique is proposed in this paper. It proves that the proposed fuzzy controlled way could decrease the numbers of active and passive filters in the micro grid hybrid energy system. Furthermore, a closed control loop for wind system connected rectifier is not essential as the wind voltage and speed variation can be automatically recognized by the advanced control loop. Therefore, the advanced control architecture decreases the system complexity without affecting the system performance. Control and design of both the dc/dc converter and three-phase inverter are presented. Moreover, the proposed scheme offers outstanding performance for overcoming the voltage and current distortions. The simulation model of the proposed system is developed in MATLAB Simulink environment and tested for the proposed control technique performance. Further, experimental results revealed the power and viability of the proposed method.
