【Abstract】 With the deepening development of new power systems, the demand for grid-forming technical equipment, such as inertia response, transient support, and rapid frequency and voltage regulation, has become increasingly urgent to address the system stability issues caused by the decreasing proportion of synchronous generator units. Flywheel energy storage, as a rotational mechanical inertia device, possesses inherent advantages for grid-forming operation. At present, flywheel energy storage can operate as an independent energy storage unit connected to the grid through power conversion devices or in combination with synchronous condensers and other equipment. The concept of grid-forming flywheel energy storage is proposed, encompassing typical technological directions such as inertial flywheel synchronous condensers, power-electronics-based grid-connected high-speed flywheel energy storage, and synchronous-machine-based grid-connected high-speed flywheel energy storage. This paper analyzes the grid-forming operation mechanisms, key technologies, and application scenarios, providing valuable references for the research and application of flywheel energy storage.更多还原
