Abstract:

The purpose of this research is to model and regulate a micro-grid with a combination of PV and wind using a Quasi Z-source inverter (QZsi)[1]. The (QZsi) offers several benefits over typical inverters, including improved buck/boost characteristics, angle output phase adjustment, decreased harmonic substance, zero filters required, and high-performance capability. The study used the DC-DC converter using a single-ended primary inductance converter (SEPIC)[9] module switching power equipment to track the maximum power point (MPP) of the PV module[8]. A new version of the power ratio variable step is used in the proposed maximum power point tracking (MPPT) approach (MPRVS) focused on the perturb and observe (P&O)[6] approach, which successfully drives the pivotal point closer to the MPP. The suggested controller combines the battery-powered, PV-wind hybrid system with loads running in a variety of situations. The independent microgrid system is designed for rural applications. The study used a SEPIC module (single-ended primary inductance converter) as a DC-DC converter[10] to track the PV module's maximum power point (MPP). Switching power equipment. The suggested method using maximum power point tracking (MPPT) is a disturb and watch (P&O)[2] method based on step variable power ratio tweaked (MPRVS) that successfully drives the pivotal point closer to the MPP.
