Study on the intelligent fuzzy control method for MPPT in Photovoltaic Voltage Grid System

MPPT (maximum power point tracking) is the main approach to improve efficiency of the PVGS (photovoltaic voltage grid system). Based on formula fuzzy control and adaptive an intelligent adaptive fuzzy control method is proposed in this paper. Its application can make the system restrain the overshoot and quickly track the MPP. Final experiments can prove its effects into improving efficiency, power factor and electric quality.
