随着时间的推移，光伏发电系统的发电量在全球范围内不断增加。光伏系统的缺点之一是它们表现出与大气条件有关的非线性I-V曲线。因此，每个光伏系统都安装了最大功率点跟踪器（MPPT）技术。其中最流行的一种技术是摄动&观察（P&O），但这种技术存在一些缺点。本文提出了一种用于分布式光伏电站P&O优化的MPPT技术。从而消除P&O的缺陷。该技术是为DPV设计的，工作在两种模式下。在模式1中，所提出的技术的决策围绕两个模块/阵列之间的相互协调进行。在此模式中，一个数组将作为领导者(L)，而另一个数组将作为追随者(F)。在模式2中，所建议的技术对两个阵列使用单独的P&O。模型是一种优越的性能模式，其效率优于P&O。而在模式2中，两种技术的效率相同。最后，在Matlab/Simulink中对所提出的技术进行了建模。在各种天气条件下对该技术进行了测试，仿真结果证明了该技术的优越性能。
With everyday passing, power generation from photovoltaic (PV) systems are getting increased around the globe. One of the drawbacks of PV systems is that they exhibit non-linear I-V curves with respect to atmospheric conditions. Therefore, maximum power point tracker (MPPT) technique is installed in every PV system. One of the most popular technique is perturb & observe (P&O) but this technique has some shortcomings. In this paper, MPPT technique is proposed which will optimize the P&O with respect to distributed PV (DPV) plant. Such that the deficiencies of P&O are removed. The proposed technique is designed for DPV and is working in two modes. In mode-1, decision making of the proposed technique revolves around the mutual co-ordination between two modules/arrays. During this mode, one array will behave as leader (L) while other array as follower (F). In mode-2, proposed technique utilizes the individual P&O for both arrays. Model is the superior performance mode in which efficiency of the proposed technique is better than P&O. While, in mode-2 both techniques have same efficiency. Finally, the proposed technique is modeled in Matlab/Simulink. The proposed technique is tested under various weather conditions and superior performance of the proposed technique is proved through simulation results.
