To improve the ability of grid-connected hybrid power systems to compensate for voltage sags, we provide FLC-based DVR in this study. Renewable energy sources are typically considered to be the only viable green energy option due to their abundance in nature and lack of environmental impact. One of the main drawbacks of most renewable energy sources is the unpredictability of their output, which is especially true with wind and solar photovoltaics. In order to protect essential loads from power supply side changes and failures, dynamic voltage restorers (DVRs) are often utilised. This study's overarching goal is to safeguard the grid-connected hybrid PV-wind power gadget against the effects of voltage fluctuations. As a backup system, DVRs that rely on batteries and Super Magnetic Energy Storage (SMES) kick in when the power drops. To make up for disruptions, the pre-sag compensation technique locks the three phase magnitudes and angles in a normal condition at the inst
