 ABSTRACT As the growing integration of renewable energy sources, inverter-based resources (IBRs) becoming new challenges for power system stability. This brings new contests to maintain system stability. The inverter that lacks inertia and making the grid more sensitive to disturbances, especially under weak grid conditions. The thesis offers a detailed performance comparison between droop control and VSG control for grid-forming inverters. The wide-spread simulation-based testing was conducted under various scenarios, including steady state operations, load variations, and fault conditions such as low voltage ride through (LVRT). GFM inverters with droop control effectively regulate power sharing. This provides improved system stability by proportionally adjusting frequency and voltage responses. VSG control further improves dynamic behavior by mimicking the inertia and damping characteristics of synchronous generators, resulting in smoother transitions and stronger fault response. Each control strategy was evaluated for its ability to handle power deviations, share load among multiple inverters and maintain system stability under both normal and fault conditions. Therefore, the careful selection and tuning of inverter control methods are critical to ensure balanced grid support, reliable power sharing, and fault ride- through performance. Advanced GFM control strategies such as droop and VSG will play a central role in enabling stable and resilient grid operation.
