摘要
针对光伏阵列发电效率低的问题,对光伏阵列最大功率点跟踪控制(Maximum Power Point Tracking,MPPT)算法进行了研究。首先介绍基于Boost电路实现MPPT原理;分析了恒定电压法、扰动观察法、增量电导法等3种经典MPPT算法,并通过搭建光伏系统MPPT仿真模型,对3种经典MPPT算法进行了仿真分析;通过对仿真结果进行对比分析得出各自的优缺点、适用范围,为基于经典算法提出新的改进措施奠定了一定基础。
The maximum power point tracking control(MPPT)algorithm of photovoltaic arrays is studied for the problem of low efficiency of photovoltaic arrays.Firstly,the principle of implementing MPPT based on Boost circuit is introduced.Then,three classical MPPT algorithms,such as constant voltage method,disturbance observation method and incremental conductance method are analyzed.The three classic MPPT algorithms are simulated and analyzed by building the photovoltaic system MPPT simulation model.Finally,through the comparative analysis of the simulation results,the advantages and disadvantages and the scope of application are obtained,which lays a foundation for the new improvement measures based on the classical algorithm.
