为了提高低功率光伏系统的能量利用效率，需要一种高效、经济的最大功率点跟踪算法。本文利用一个由1080-Wp光伏阵列连接到1 kw永磁直流电机-离心泵组组成的实验装置，对独立光伏泵系统中使用的增量电导MPPT算法进行了实验评估。特别着重于评估两种常用的实现技术：参考电压摄动和直接占空比摄动。研究了算法参数对系统行为的影响，计算了不同天气条件下的能量利用效率。将增量电导算法的性能与常用的扰动和观测MPPT算法进行了比较，并确定了每种技术的各种优点和缺点。
An efficient, cost-effective maximum power point tracking (MPPT) algorithm is required to improve the energy utilization efficiency of low power photovoltaic (PV) systems. This paper presents an experimental evaluation of the incremental conductance MPPT algorithm when employed by a standalone PV pumping system, using an experimental installation comprised of a 1080-Wp photovoltaic array connected to a 1-kW permanent magnet dc motor-centrifugal pump set. Particular focus is given to the evaluation of the two commonly utilized implementation techniques: reference voltage perturbation and direct duty ratio perturbation. The influence of algorithm parameters on system behavior is investigated and the energy utilization efficiency is calculated for different weather conditions. The performance of the incremental conductance algorithm is compared to that of the commonly used perturb and observe MPPT algorithm and the various advantages and drawbacks of each technique are identified.
