摘要
文章结合光伏阵列的数学模型及其输出特性,提出一种固定电流法结合扰动法的控制方法。对该方法进行了理论分析,并在Matlab/Simulink环境下建立了光伏发电系统的仿真模型。仿真结果表明,光伏系统在正常情况下以及光照强度发生突变的时,都能够快速得追踪到最大功率点,该方法具有良好的控制性能。
In the photovoltaic power generation system, maximum power point tracking technologyis a very important. The mathematical model and output characteristics of PV array are analyzed,and then a control method that combines constant current method with perturbation method isproposed. A theoretical analysis of proposed method is carried out and a simulation model isbuilt in Matlab/Simulink environment. The simulation results show that the system can quicklytracking the maximum power point at normal light intensity or sudden change light.
