摘要
为了实现光伏系统开机过程和光照强度发生较大变化时对最大功率点(MPP)的快速追踪,提出了一种新型变步长与基于光照变化因子的补偿步长相结合的电导增量控制算法,并建立了该算法的数学模型及仿真模型。仿真结果表明提出的控制算法能够快速、准确地进行最大功率点的跟踪且能够消除振荡现象,表现出了良好的动态性能。
In order to achieve the fast tracking of the MPP （maximum power tern is in the boot process or the solar irradiation has undergone major changes point） when the photovohaic sys- A novel conductance increment control algorithm is proposed, which combine the new variable step size method with the compensation step method that is based on illumination changes. The mathematical model and simulation model of the proposed algorithm has been established. The simulation results show that the proposed control algorithm can fast and accurately track the MPP with the oscillation phenomenon eliminated, representing good dynamic performance.
