With the increasing proportion of new energy in power grid system, the domestic capacity of peak regulation, frequency regulation and voltage regulation is increasing, which greatly affects the flexibility of the power grid. In this regard, the focus is on analyzing and researching the related fields of grid-forming energy storage. Firstly, the technical characteristics of grid-following and grid-forming control are compared and analyzed, and the development status of grid-forming energy storage in Xinjiang is summarized. At the same time, a demonstration project of a grid-forming energy storage power station in Xinjiang is selected to test the low voltage ride-through, inertia response and damping characteristics, and a grid-connected test method for grid-forming energy storage power stations covering multi-level and full-scale scenarios is proposed. The test results can provide reference for grid-connected performance evaluation of grid-forming energy storage. Finally, the development of grid-forming energy storage in Xinjiang is predicted and analyzed, and the development advantages of grid-forming energy storage in new energy-rich areas are summarized.
