Current control for the micro-grid connected inverter based on fuzzy control

In this paper, the three-level inverter of micro-gird is used to improve output current wave-form, power factor and power energy transmission. Due to the Randomness and fluctuation of Circuit parameters and the signal, a closed-loop control strategy of fuzzy hysteresis current controller and the direct current side voltage fuzzy Proportional-Integral controller is introduced. The obtained results showed the reliability and feasibility of the above mentioned control strategy in MATLAB Simulation.
