Implementation and Analysis of Hybrid Solar PV and Wind Energy based Microgrid

The hybrid energy system combines two or more sources of energy to produce and consume the energy efficiently, which results in a flexible source. Hybrid source in this work is made up of a combination of solar and wind energy. The result is superior because these two resources are complementary. Maximum power is extracted from two renewable energy sources such as wind and solar energy. Fuzzy logic method & Modified Power Variable Ratio Step based Perturb and Observe algorithms are utilized in this MPPT approach to extract the highest wind and solar power output with less or no oscillation than other MPPT methods. SEPIC converter is introduced to raise or reduce the output voltage level while the Z- Source inverter is used for conversion of DC to AC. MATLAB is used to model solar, wind, battery, converter, inverter and create rules for fuzzy algorithms. Finally, the extracted maximum power from two sources is given to the microgrid.
