    Abstract:

    Under the condition of partial shadow,the power-voltage (P-V) characteristic curve of photovoltaic array presents multiple peaks.In the multi-peak case,the conventional maximum power point tracking (MPPT) algorithm is prone to fall into local optimal solution,which affects the solar energy conversion efficiency.This paper presents an MPPT algorithm based on fuzzy control with load voltage scan.At first,the voltage scanning method is used to quickly reach the maximum power point,and then the fuzzy control algorithm is used to stabilize the maximum power point.The algorithm improves the convergence speed of MPPT under multi-peak condition,which can solve the problem of voltage spike produced on the switch tube during the particle switching.The feasibility and practicability of the algorithm are verified by Matlab simulation and hardware experiments.
