摘要
针对光伏电池最大功率点具有线性的特点,本文通过线性拟合把操作点锁定在最大功率点附近,再结合扰动观察法准确地追踪MPP点,从而提出改进的MPPT算法。相较于传统的扰动观察法而言,改进的MPPT算法能够更加快速、准确且少波动地追踪MPP点。最后,通过在Matlab上搭建仿真实验平台验证了所提出算法的有效性和优越性。
The problem of the maximum power point tracking in photovoltaic cell which has the property of linear is investigated in this paper. Through using linear fitting method to lock the vicinity of MPP and applying disturbance and observation method to make sure the position of MPP,the improved MPPT algorithm is proposed. Compared with the traditional disturbance and observation method,the improved MPPT algorithm has the characteristics of faster,more accurate and less fluctuation. Finally a simulation platform is built based on the MATLAB,the Simulation results show that the effectiveness and the merits of the proposed algorithm.
