Three Phase Grid Connected Photovoltaic systems Using Effective Linear Stabilization System with fuzzy logic controller
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
This paper presents a robust linear stabilization scheme for a three-phase grid-connected solar system to control the output current of solar cell connected to the grid and dc-link voltage to extract maximum output power from solar units. The scheme is mainly based on the design of a robust controller using a feedback linearization approach, where the robustness of the proposed scheme is ensured by undertaking nonlinearities within the solar system model. In this paper, the nonlinearities are modelled as designed nonlinearities are based on the matching of satisfactory conditions. The performance of the proposed linearization scheme is evaluated on a three-phase grid-connected solar system in terms of delivering maximum power under undesirable conditions.
