| 摘 要： | 最大功率点跟踪技术(Maximum Power Point Tracking,简称MPPT)在太阳能光伏发电系统中占有重要地位.针对现有MPPT方法动态性能和稳态性能难以兼顾的不足,提出了一种同时具有良好动态性能和稳态性能的MPPT方法.该方法的核心思想是,将MPPT过程看作求解函数最大值的最优化问题,用迭代的方法迅速找到并稳定工作在最大功率点.以牛顿法为例,在300 Wp三相光伏并网逆变系统上进行了算法实现.并根据实际情况对算法进行了设计,以达到更好的动态性能.仿真和实验结果验证了该方法的有效性.

| Abstract: | The maximum power point tracking(MPPT) technique is important to solar photovoltaic systems.For the draw-backs of the existing MPPT methods,a novel MPPT method is proposed to cover both good dynamic performance and steady-state performance.The MPPT process is treated as an optimization problem,and the Newton method is implemented on a 300 Wp three-phase grid-connected PV system.The algorithm is properly designed according to the real system to improve the dynamic performance.It is shown that the proposed me... |
