摘要

由于不匹配条件，例如部分遮阳条件，光伏(PV)发电系统具有可变的效率。为了补偿这种情况，使用最大功率点跟踪(MPPT)系统来搜索导致光伏系统最大功率提取的工作点。因此，本文提出并分析了一种替代著名的基于二分法的扰动与观测(P&O)算法。这样可以大大提高改进后的P&O的效率和跟踪速度，如本文给出的数值评价所示。

Improved P&O algorithm for distributed MPPT PV configurations

The photovoltaic (PV) power generation systems have a variable efficiency due to mismatching conditions, such as a partial shading condition. To compensate this situation, the Maximum Power Point Tracking (MPPT) systems are used to search the operating point that results in a maximum power extraction from the PV system. Thus, the present paper proposes and analyses an alternative to the well-known MPPT algorithm Perturb & Observe (P&O), which is based on the bisection numerical method. In this way, the efficiency and tracking speed of the modified P&O can be greatly improved as illustrated in the numerical evaluation presented in this paper.
