<p>As civilizations become progressively more dependent of electricity for various aspects of every day life, ensuring an uninterrupted and stable supply of power is cruicial. Hybrid Renewable Energy System (HRES) compromises an expanded and decentralized approch for energy generation, decreasing exposure to disruptions caused by extreme weather events. Accordingly, this paper proposes multiple Renewable Energy Sources (RESs) to optimize energy management and grid supply thereby contributing a stable and reliable system. The developed system combines Photovoltaic (PV) panels, Doubly Fed Induction Generator (DFIG) based wind system, battery and an electrical connection to grid thereby maximizing renewable energy integration. The proposed research aims at establishing a high step-up Modified Boost Converter (MBC), with Improved Black Widow Optimzed Proportional Integral (IBWO-PI) controller for managing the output power of PV efficiently under varying environmental conditions. The proposed MBC addresses the limitations of conventional Boost converters by stepping up low voltage appropriate for grid integration. Consequently, the proposed control mechanism ensures improved stability, efficiency and reliable performance of overall system by offering faster convergence with precise control. The DFIG based wind system linked to grid allows for efficienct conversion of energy and compatibility to grid. Additonally, the battery with bidirectional converter provides energy storge and power backup to balance demand, with flow of energy to both battery and grid. This research is verified using Matlab and the validation outcomes demonstrate that proposed system ranks with improved converter efficieny of 96.77% and reduced Total Harmonic Distortion (THD) of 1.83% resulting in effective synchronization of grid, in constrast to state-of-art approaches. The proposed work ensures optimal utilization of solar, wind and storage resources contributing to maximized renewable energy integration.</p>
