摘要
针对光伏发电系统的最大功率点跟踪原理进行了详细的分析和阐述,介绍了传统扰动观测法的优缺点,在此基础上提出了基于模糊控制理论的最大功率点跟踪算法.通过Matlab/simu-link进行系统仿真,给出了光照突变时扰动观测法和模糊控制法的最大功率点跟踪曲线.实验结果表明,该模糊控制算法具有更优的系统响应特性和稳态特性.
Based on analying the principle of maximum power point tracking in photovolatic energy generation system, this paper introduces the merit and shortcomings of the disturbance observation. Then it brings up the fuzzy control theory based on the maximum power tracking algorithm. Through simulation by Matlab＆simulink, it gives the maximum power point tracking curve when the illumination is changing. The experimental results show that the fuzzy control method has the better system and steady-state response characteristics.
