Most research on this technology is currently focused on micro grid application scenarios, and there is no system level research on large grid application. Given this, a modeling method of grid-forming BESS is proposed based on the principle of grid-forming technology. Then the mechanism of grid-forming BESS participating in power sharing is deduced based on the essential properties of voltage source, and the capacity for its proportion in the power grid is discussed. Finally, taking a domestic project as an example, a grid-forming BESS model is built
