基于功率修正算法的光伏发电系统最大功率点跟踪控制策略
Maximum Power Point Tracking Control Strategy for Photovoltaic Power Generation System Based on Power Correction Algorithm
摘要
Abstract
Combining the parameters of photovoltaic cell, illumination, temperature and real-time output current, the modified formula was used to calculate the actual maximum available power.Considering the actual output current of the photovoltaic cell and its maximum available power calculation value, the duty ratio of the DC/DC conversion circuit of the photovoltaic system is further determined, and the output power of the photovoltaic system is adjusted accordingly, so that the photovoltaic cell operates stably at the maximum power point.The method does not require a voltage sensor, and the method is simple and easy to implement.Compared with the disturbance observation method, the system response speed can be effectively improved, the steady state power fluctuation can be suppressed, and the system power loss can be reduced.关键词
