Integrating Renewable Sources for Grid Connected Distributed Generation System Using Fuzzy Controller Fed PMSM Drive

Abstract

this model proposes a method for in use a grid connected hybrid system. This system collected of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. As the variation happen in temperature and irradiation during power delivery to load, Photo voltaic (PV) system becomes uncontrollable. In organization with PEMFC, the hybrid system output power become convenient. Two operation modes are the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. All MPPT methods follow the same goal that is maximizing the PV system output power by tracking the maximum power on every operating condition. Maximum power point tracking technique (Incremental conductance) for photovoltaic systems was introduced to maximize the produced energy. The organization of two control modes, organization of the PV array and the PEMFC in the hybrid system, and determination of orientation parameters are presented. The proposal operating approach systems with a flexible operation mode change always operate the PV array at maximum output power and the PEMFC in its high efficiency performance band. Also thus improving the presentation of system operation, enhancing system stability, and reducing the number of operating mode changes. The proposed concept can be implemented to fuzzy controlled grid connected hybrid PV/PEMFC/Battery using PMSM drive applications using Matlab/Simulink software.
