Abstract

In this study, a fuzzy logic based maximum power point tracking control algorithm was developed to obtain maximum power continuously from a simulation model of a PV system. Using this simulation model, codes suitable for the TMS320F28335 Digital Signal Processor (DSP) were generated by the embedded code generation method. In this way, the developed algorithm was generated, compiled, sent, and made ready for use in applications with an optimum code structure. The algorithm developed has the task of providing the power demanded by the load unit in a stable and continuous manner; It fulfills this task by providing maximum efficiency from PV panels by Tracking the Maximum Power Point and increasing the power obtained. In addition, the current and voltage of the DC bus as well as the PV panel unit are continuously monitored and used as input data for the algorithm's fuzzy logic controller.

Fotovoltaik Bir Sistemde, Maksimum Güç Noktası Takibi için Bulanık Mantık Tabanlı Bir Denetleme Algoritmasının Geliştirilmesi

Abstract

Bu çalışmada, oluşturulan benzetim modeli kullanılarak, bir PV sisteminden maksimum güç elde etmek için bulanık mantık tabanlı bir maksimum güç noktası takibi denetleme algoritması geliştirilmiştir. Bu benzetim modeli kullanılarak, gömülü kod üretimiy öntemi ile TMS320F28335 Dijital Sinyal İşlemcisi için uygun kodlar oluşturulmuştur. Böylelikle geliştirilen algoritma kodları derlenmiş, işlemciye gönderilmiş ve optimum kod yapısı ile uygulamalarda kullanıma hazır hale getirilmiştir. Geliştirilen algoritma, yük biriminin talep ettiği gücü kararlı ve sürekli bir şekilde sağlama görevini; Maksimum Güç Noktası Takibi yaparak PV panellerinden azami verim sağlanması ile yerine getirmektedir. Ayrıca, DC bara ve PV panel ünitesinin akım ve gerilim verileri sürekli olarak izlenmekte ve algoritmanın bulanık mantık denetleyicisinin girişleri olarak değerlendirilmektedir.
