Due to the high penetration rate of power electronic equipment and renewable energy penetration. Traditional power system is experiencing a trend of reduced inertia and weakened system strength, leading to increasingly severe stability issues. Grid-forming (GFM) battery energy storage system (BESS) has attracted widespread attention due to its similar control response characteristics to conventional generators. And GFM BESS is regarded as a crucial piece of equipment supporting the construction of new-type power systems. This work points out the current bottlenecks and challenges faced by this technology, as well as feasible solutions. The research results show that grid-forming control technology can effectively enhance the inertia and damping characteristics of the power grid, providing voltage and frequency support to the system. It holds promising application prospects in new-type power systems with a high proportion of renewable energy and power electronic equipment.
