Abstract

The constant fluctuations in the maximum power obtained from Photovoltaic (PV) systems are due to variations of temperature and irradiance. Maximum Power Point Tracking (MPPT) techniques are used to guarantee the best possible efficiency and performance for the PV systems. In this paper, an Incremental Conductance (IC) MPPT technique based on adaptive controllers is proposed. This paper presents two different types of adaptive PI controllers, including optimized Fractional Order Adaptive PI (FOAPI), and Single Perceptron Adaptive PI (SP-API). The IC technique along with the adaptive controllers ensure accurate extraction of maximum power under sudden changes and different weather conditions. Moreover, machine learning is utilized to initialize the duty cycle of PV system converter, where different regression models are compared and the model with the least Root Mean square error (RMSE) is exploited. Three case studies are carried out to compare and validate the performance of the suggested adaptive MPPT controllers.

并网光伏系统数据驱动最优自适应MPPT技术

从光伏（PV）系统获得的最大功率的持续波动是由于温度和辐照度的变化。最大功率点跟踪（MPPT）技术用于保证光伏系统的最佳效率和性能。本文提出了一种基于自适应控制器的增量电导（IC） MPPT技术。本文提出了两种不同类型的自适应PI控制器，包括优化分数阶自适应PI （FOAPI）和单感知器自适应PI （SP-API）。集成电路技术和自适应控制器确保在突发变化和不同天气条件下准确提取最大功率。此外，利用机器学习对光伏系统变流器的占空比进行初始化，比较不同的回归模型，并利用RMSE最小的模型。进行了三个案例研究，以比较和验证所建议的自适应MPPT控制器的性能。
