摘要
提出了一种通过追踪直流侧母线电压控制参考信号的实时调整环节的扰动观察算法,并与常规的扰动观察法进行了对比。仿真结果证明,该方法能快速、精确地跟踪最大功率点,稳态精度较高,提高了光伏电池的利用率。
The perturbation and observation（PO） method is commonly used in the photovoltaic array maximum power point tracking（MPPT） system due to its succinctness and high tracking efficiency.However,the PO algorithm can be confused during those time intervals characterized by rapidly changing atmospheric conditions.An improved PO algorithm by tracking reference signal controlled by DC voltage was proposed.The contrastive simulation results of the improved and conventional algorithm were presented to demonstrate its effectiveness.
