Tóm tắt

Renewable energy sources have been becoming an optimal substitute for conventional fossil energy sources. The studies on solar systems are extensively increasing because of the broad availability of this energy resource and it can be seen as a robust energy resource in the near future. The maximum output power of the solar panel is significantly influenced by the irradiant and the temperature on the surface of the solar panel. As a result, it is necessary to implement the effective controllers for the maximum power point tracking (MPPT) of the solar panel in various environmental conditions. This paper describes the steps of implementing the control algorithms based on the P&O method and the fuzzy logic for MPPT of the solar panel. The LabVIEW software was chosen to create the human machine interface (HMI) for easily monitoring the operation process of the whole system. The codes of the control algorithms were written by using C programming language and then were compiled in Dynamic Link Library (DLL) extension using Pelles C software to be called in the LabVIEW environment.
