Abstract - The increasing integration of renewable strength resources (RES) consisting of sun and wind electricity into current power grids calls for efficient and reliable energy conversion techniques. one of the maximum promising answers for grid-linked renewable strength systems is the multilevel inverter (MLI), which enables high-electricity and high-voltage applications with improved efficiency and decreased general harmonic distortion (THD). Multilevel inverters provide advanced strength quality, decrease switching losses, and better voltage control, making them perfect for huge-scale grid integration of renewable strength structures. This research explores the design, operation, and performance of multilevel inverters for grid integration of renewable electricity assets. various multilevel inverter topologies, such as cascaded H-bridge (CHB), neutral-point clamped (NPC), and flying capacitor (FC) inverters, are analyzed based totally on their performance, harmonic performance, and control techniques. A simulation-based approach the usage of MATLAB/Simulink is implemented to evaluate the effectiveness of MLIs in grid-related renewable strength programs. The have a look at also discusses modulation techniques which includes sinusoidal pulse width modulation (SPWM) and area vector modulation (SVM) for enhancing inverter performance. The outcomes indicate that MLI-based grid integration complements strength excellent, minimizes harmonic distortion, and optimizes renewable power utilization. future research ought to focus on hybrid multilevel inverter configurations, AI-based manage techniques, and real-time grid synchronization techniques to enhance scalability and operational performance in cutting-edge power structures.
