为了保证光伏发电系统具有最高的发电效率,必须使光伏发电系统工作于全局最大功率点,对光伏发电系统的最大功率点跟踪技术进行了研究.由于光伏电池输出特性的非线性,采用基于改进的模糊控制算法最大功率点跟踪技术,模糊控制器可以根据偏离平衡位置的程度产生自适应跟踪步长,通过优化控制算法改善系统的不对称性,提高最大功率点跟踪精度.通过MATLAB建立仿真模型并进行实验研究,结果表明光伏发电系统最大功率点的跟踪精度及跟踪速度均明显优于传统算法,可使光伏发电系统更高效地运行.
Research on photovoltaic maximum power point tracking technology based on the improvement of fuzzy control algorithm
In order to achieve the highest power generation efficiency,the photovoltaic power generation system must always be operated at the global maximum power point.The maxi-mum power point tracking technology of photovoltaic system is studied in this paper.Due to the nonlinearity of the output characteristics of photovoltaic cells,the maximum power point tracking technology based on the improved fuzzy control algorithm is adopted.The fuzzy controller can generate an adaptive tracking step according to the degree of the deviation from the equilibrium position.The asymmetry of the system is improved by optimizing the con-trol algorithm,and the maximum power point tracking accuracy is improved.The simula-tion model is established by MATLAB and the experimental research is carried out.The simulation results and experimental results show that the tracking accuracy and tracking speed of the maximum power point of the photovoltaic power generation system are signifi-cantly better than the traditional algorithm,which can make the photovoltaic power genera-tion system run more efficiently.
