The perturbation and observation method (P&O method) is commonly used for maximum power point tracking in wind energy conversion systems. However, the selection of a suitable step size for this method is the key challenge when employing this technique. To address this, the paper presents a new method, called the FLC‐P&O method, in which a combination of fuzzy logic control (FLC) and the conventional P&O method is used. Both simulation and experimental results are presented in order to demonstrate the performance of the proposed MPPT method. Experimental testing is performed on both a laboratory wind simulator and a practical wind turbine. The results confirm that the FLC‐P&O method can provide better maximum power point tracking performance compared to the conventional P&O method. Moreover, the implementation and testing of the proposed technique on a practical wind turbine can extract more energy compared to conventional P&O. All findings are verified experimentally. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

使用FLC-P＆O方法的独立风能转换系统的最大功率点跟踪

微扰和观测方法（P＆O方法）通常用于风能转换系统中的最大功率点跟踪。但是，在采用该技术时，为该方法选择合适的步长是关键挑战。为了解决这个问题，本文提出了一种称为FLC-P＆O方法的新方法，其中结合了模糊逻辑控制（FLC）和常规P＆O方法。给出了仿真和实验结果，以证明所提出的MPPT方法的性能。在实验室风力模拟器和实际风力涡轮机上都进行了实验测试。结果证实，与传统的P＆O方法相比，FLC-P＆O方法可提供更好的最大功率点跟踪性能。此外，与常规的P＆O相比，在实际的风力涡轮机上实施和测试所提出的技术可以提取更多的能量。所有发现均通过实验验证。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
