光伏发电系统中最大功率点跟踪技术是提高光伏发电效率的主要技术,基于在线短路电流法和黄金分割法,提出一种全新的MPPT算法,即改进黄金分割法;与传统MPPT算法相比,该算法既保证了最大功率跟踪的快速性,又保证了其精确性;最后,通过Matlab仿真模型进行仿真,结果验证了该算法的优越性.

MPPT is the main technology which can improve the generating efficiency of photovoltaie system, a new MPPT algorithm based on the online short-circuit current method and center section search is presented . Compared with the traditional algorithm of MPPT, the merits of the algorithm are that it not only ensures the speediness, also has a well accuracy. Finally, the MATLAB software were used to build a simulation model of photovohaic system and simulation results show the effectiveness of proposed method.
