Abstract: The rapid growth of Inverter-Based Resources (IBR) like solar and wind energy is creating challenges for power grids. As traditional synchronous generators become less common, power systems have less inertia, making it harder to keep the frequency stable during disruptions. The grid's ability to handle faults is also weaker, which affects reliable operation. These problems show the need for advanced solutions to keep the grid stable when more renewable energy is used. Grid-Forming (GFM) inverters are a promising solution because they can behave like traditional generators, providing virtual inertia, voltage control, and frequency support to help maintain grid stability. Given these challenges, there is an urgent requirement for innovative solutions to enhance grid stability as the penetration of renewable generations is growing continuously. This thesis focuses on developing a GFM inverter control strategy to improve grid performance with high IBR levels. It specifically considers a p-f droop-controlled GFM inverter for large power systems dominated by reactance. The proposed control approach is tested using the Vehicle-to-Grid (V2G) capability of an Electric Vehicle (EV), where the GFM inverter helps stabilize the power system under different abnormal conditions. The results show that the GFM inverter improves stability, supports frequency regulation, and makes it easier to integrate renewable energy. This work helps advance the use of GFM inverters as a key technology for building resilient and sustainable power systems.
