Abstract

Dynamic Stability Analysis of a Connected Wind and Photovoltaic Micro Grid System is proposed in this research work using the Voltage Source Converter (VSC) and the Fuzzy Control VSI (Voltage Source Inverter) integrated into an electrical grid. The wind farm consist of a Permanent Magnet Synchronous Generator (PMSG) powered by a wind turbine. The power outputs of PMSG and the photovoltaic system are fed to a common DC link from a Voltage -Source Converter (VSC) and DC-DC boost converter together with a supercapacitor, to soften the generated energy delivered to the micro-grid. This work proposes a control scheme with a fuzzy logic structure to achieve the stability of the proposed system while obtaining maximum power extractions for the wind and the photovoltaic system. Along with these, renewable sources such as the battery and fuel cell are also integrated into DC link where the actions are observed. The analysis and total design is done in the MATLAB software with graphic representations of dynamic performance.
