INTRODUCTION: The output of photovoltaic (PV) arrays has nonlinear characteristics and is affected byambient conditions, so maximum power point tracking (MPPT) is crucial for efficient photovoltaic power generation.
OBJECTIVES: This study aims to propose an MPPT control strategy based on improved perturbation and observation (P&O) method to overcome the shortcomings of traditional MPPT methods.
METHODS: The method proposed integrates slope control and fuzzy control algorithms for hybrid control to achieve adaptive adjustment of control step size. In addition, the simulation test for start-up and sudden changes in operating conditions of PV were conducted to verify the practicability and progressiveness of the improved method proposed.
RESULTS: The results confirm that the improved method proposed can reduce the output fluctuations of PV array and achieve shorter MPPT time and higher MPPT efficiency.
CONCLUSION: The improved MPPT method has better MPPT performance, which provide effective reference for further improving the efficiency of PV power generation.
