A Weighting Slope MPPT Method Based on Sun Tracking Applied in PV System

Abstract:

To maximize the photovoltaic (PV) cell output power, the sun tracking control is applied to keep the sunlight perpendicularly irradiated on the surface of the solar array battery firstly, and then the control strategy of weighting-slope method is proposed to track the maximum power point (MPPT) in the PV system. To verity the effectiveness of the adopted methods, both numerical simulation and experiment are carried out. The results show that the weighting-slope method significantly improved the output power of PV array comparing with perturbation and observation method.
