A key application of BESS is enabling autonomous power system operation, independent of the main transmission network, while maintaining high-quality, reliable three-phase voltage to protect plant equipment. This study investigates various multilevel inverter topologies for BESS applications through simulation. It includes both quantitative analyses, evaluating output performance, and qualitative analysis, assessing reliability, modularity, and functionality. Multilevel converters are state-of-the-art for medium-voltage (MV) high-power systems, widely used in industries such as mining, marine, and oil and gas, and in integrating renewables into the grid. The focus is on three-level and five-level converter topologies with a common DC-link, supporting bidirectional energy flow. New hybrid topologies and modulation techniques are developed to optimize cost, reliability, and efficiency. All simulations are conducted under identical conditions using MATLAB/Simulink.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> Siripireddy Latha Dr. J.
