on march 31, the second phase of the 100 mw/200 mwh energy storage station, a supporting project of the ningxia power’s east ningxiacomposite photovoltaic base project under chn energy, was successfully connected to the grid. this marks the completion and operation of the largest grid-forming energy storage station in china.

the second phase, a 100 mw/200 mwh energy storage station, was constructed with a grid-forming design. it can simulate the operating characteristics of synchronous generators by increasing the overcurrent capacity, provide system virtual capacity and short-circuit capacity, support synchronous voltage for the grid, suppress transient overvoltage, improve impedance characteristics, effectively enhance the grid's ability to accept new energy, and provide technical support for the next steps in reducing or replacing equipment such as phase shifters.

this project marks the first successful application of grid-forming technology at the “desert, gobi and barren land”new energy base, pioneering a new application scenario for grid-forming technology to enhance the short-circuit capacity of ultra-high voltage direct current transmission end new energy power systems and improve system rotational inertia. it will effectively support the construction of a robust transmission grid, contribute innovative solutions to advance energy transformation, and achieve the "dual carbon" goals. the completion of the project significantly promotes the ability of the east ningxia power grid and the chn energy east ningxia 2 gw composite photovoltaic base to consume new energy. going forward, various tests and performance experiments will be carried out to provide data support for the testing and standard setting of grid-forming energy storage.
