光伏发电机最常用的最大功率点跟踪（MPPT）算法之一是电导增量（INC）算法。然而，该算法在高扰动频率下的操作特性，当系统对MPPT扰动的响应从未被允许解决时，尚未在文献中得到解决。本研究的特点是系统的行为，在这种操作模式下，实验为一个独立的光伏系统与直流电机泵负载。结果表明，INC算法运行在一个高的扰动率提供了更高的能量利用效率和更好的系统性能，尽管由此产生的非周期性波形的系统。
One of the most commonly utilised maximum power point tracking (MPPT) algorithms for photovoltaic (PV) generators is the incremental conductance (INC) algorithm. Yet, the operating characteristics of this algorithm at high perturbation frequencies, when the system response to MPPT perturbations is never allowed to settle, have not been addressed in the literature. This study characterises system behaviour in this operating mode experimentally for a standalone PV system with a dc motor-pump load. Results show that the INC algorithm operating at a high perturbation rate offers higher energy utilisation efficiency and better system performance despite the resulting non-periodic waveforms of the system.
