This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization. . Sources such as photovoltaics, wind turbines, battery storage, fuel cells, and other technologies like high-voltage DC transmission interconnections all rely on an inverter to connect and interface with the grid. Unlike grid-following inverters, which rely on phase-locked loops (PLLs) for synchronization and require a stable grid connection, GFMIs internally. . Although the performance of grid-connected inverters can be adaptively adjusted according to the SCR to ensure stable operation under a wide range of SCR variations, this significantly reduces their responsiveness and makes it challenging to meet grid connection requirements. The higher penetration and longer distance from the renewable energy source to the main power grid result in lower. .
