Renewable energy sources, which are plentiful and eco-friendly, are the preferred global choice for providing green energy. However, the intermittent nature of renewable energy sources such as wind and solar PV, which depend on wind speed and solar irradiance respectively, leads to power fluctuations. To mitigate these fluctuations and protect sensitive loads from power distribution side faults, a dynamic voltage restorer (DVR) is commonly utilized. This research focuses on addressing voltage fluctuations in a grid-connected hybrid PV-wind power system. A battery energy storage system (BESS) and super magnetic energy storage (SMES) based DVR is employed as a compensating device during voltage sag conditions. The proposed compensation method uses presag compensation, which captures and stores the real-time voltage magnitude and angle under normal conditions at the point of common coupling (PCC). This stored data is used for compensation during disturbances. The study considers both symmetrical and asymmetrical voltage sags, with compensation performed using Hardware and MATLAB Simulation.
