Global MPPT Control of Solar Photovoltaic System for Energy Saving Based on the Fuzzy Strategy

Abstract:

In this paper, a strategy of global Maximum Power Point Tracking (MPPT) for energy saving based on fuzzy logic control is presented and its characteristic is to combine intelligent booster with the fuzzy MPPT control technology. Through detecting the change of the power output of the solar photovoltaic system, maximum power point is tracked by regulating the duty ratio of switch tube automatically. The simulation results show: when the sunlight intensity is changed from weak to strong, the changes of power can be rapidly tracked and it always closes to the maximum power point and has good stability.
