摘要:
针对光伏发电系统传统跟踪算法精度低、适应性差、振荡剧烈等问题，提出一种改进的变步长爬山算法。该算法采用了二分变步长与固定步长结合的新型爬山算法，实现了对光伏MPPT系统的控制。仿真结果表明，与传统爬山搜索法相比，改进算法的跟踪速度提高了1.57%，稳定时间减少了1.2%，输出效率提高了5.4%左右，同时还极大地减少了在最大功率点附近的振荡幅度，提高了系统的稳定性。
Abstract:
In order to?solve?the problems of the low accuracy, poor adaptability and drastic oscillation in traditional photovoltaic（PV） power generation maximum power point tracking（MPPT）system, an improved variable step size algorithm was proposed. The paper puts forward an new tracking algorithm which combines 1/2 variable step method with the fixed step method, which to control PV-MPPT system. The simulation results indicate that compared with the traditional method，the tracking speed of proposed method is increased by 1.57%, the stable time reduced by 1.2%，the output efficiency is increased by 5.4%，meanwhile it significantly reduced the oscillation amplitude near the maximum power point, improved the stability.
