Abstract

In this paper, a quasi-Z-source inverter (QZsi) is used to model and regulate a hybrid photovoltaic (PV) wind microgrid. This inverter has significant advantages over conventional inverters, including superior buck/boost characteristics, high power performance features, a lack of filter requirement, lower harmonic contents, and the ability to control phase angle output. To maintain high voltage, gain during maximum power point tracking (MPPT) operations, as DC-DC switching power equipment, a SEPIC converter is employed. The suggested controller combines distributed generation (DG) with loads effectively and operates with battery systems, wind turbines, and hybrid PV under a variety of operational situations. Only rural areas can use the recommended freestanding microgrid technology. Using MATLAB Simulink, the proposed microgrid system has been tested under a variety of load-cutting, solar, wind, and environmental conditions. The results of the studies which were run on Simulink, demonstrate that a microgrid with QZsi architecture can function successfully in this situation.
