Abstract

Photovoltaic (PV) cells have non-linear properties influenced by environmental factors, including irradiation and temperature. As a result, a method known as maximum power point tracking (MPPT) was implemented to boost the PV cells' efficiency and make the most of the energy they could provide. The traditional perturb and observe (P&O) approach for determining the maximum power point tracking (MPPT) has various drawbacks, including poor steady-state performance, increased oscillation around the MPP point, and delayed reaction. As a result, this work aims to present a hybrid fuzzy logic (FL) and P&O MPPT approach to improve the PV system's performance coupled to the lithium battery storage system. Matlab/Simulink is used to bring the suggested technique to life, after which its efficacy is evaluated in the context of rapid changes in the irradiance level. According to the findings of the simulations, the suggested strategy has the potential to enhance the steady-state performance of PV systems in terms of oscillation and time response. Finally, the proposed results are compared with that obtained by the conventional P&O technique, and the stress of PV power is limited to ∆P=1kW and the overshoot power is limited to 5%.

基于人工智能最大功率点控制器的光伏/电池混合系统

光伏（PV）电池的非线性特性受辐照和温度等环境因素的影响。因此，人们采用了一种称为最大功率点跟踪（MPPT）的方法来提高光伏电池的效率，并充分利用它们所能提供的能量。用于确定最大功率点跟踪（MPPT）的传统扰动和观测（P&O）方法存在各种缺点，包括稳态性能差、在最大功率点附近振荡加剧以及反应延迟。因此，本研究旨在提出一种混合模糊逻辑（FL）和 P&O MPPT 方法，以提高与锂电池储能系统耦合的光伏系统的性能。我们使用 Matlab/Simulink 将所建议的技术付诸实践，然后在辐照度快速变化的情况下对其功效进行评估。根据模拟结果，建议的策略有可能在振荡和时间响应方面提高光伏系统的稳态性能。最后，将所建议的结果与传统 P&O 技术的结果进行了比较，并将光伏功率应力限制在 ∆P=1kW 范围内，将过冲功率限制在 5%范围内。
