Abstract

The paper research the MPPT method of photovoltaic PV array based on the combination of RBF neural network and PI fuzzy control. This MPPT method can accurately follow the maximum power point of the photovoltaic PV array and reduce the fluctuation of output power, voltage and output current at the maximum power point of the photovoltaic PV array, thereby reducing losses due to system oscillations.
