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

For this study, we looked at one renewable energy microgrid (MG). When renewable energy sources like wind and hydro are abundant, wind-hydro MGs may produce power. The primary control device of MG is an inverter for voltage source (VSI), which works on indirect current control. By removing harmonics from nonlinear loads, controlling voltage in the occurrence of events like load imbalance, and compensating reactive power at the connection point based on system demands, this VSI improves energy quality. It may be used to determine the power balance in the event that units of production, storage, and consumption are altered. A method called weighted zero attraction with least square error control is used for VSI switching pulses. A MATLAB/Simulink model was created to describe the MG's performance in both static and dynamic environments, subjected to linear and nonlinear stresses.
