Sineng Electric, in close collaboration with the project owner and the Hunan Electric Test Research Institute (Hunan Xiangdian), has successfully completed a full-process grid-forming, grid-following and off-grid test at the Changsha Ningxiang Guanshan 100MW/200MWh energy storage power station, underlining that the company’s related technology has entered a new stage of large-scale global application.
As the first energy storage power station in Hunan Province equipped with grid-forming capability, the project is powered by Sineng’s new-generation 1250kW Central PCS and 5MW Central PCS MV turnkey station, featuring the company’s second-generation enhanced hybrid grid-forming technology.
Despite challenges including high on-site temperatures, tight schedules and complex multi-party coordination, the entire test campaign was completed within one week, its scope covering nine major categories—inertia response, primary frequency regulation, damping control, black-start, phase jump tolerance, active power control, grid voltage adaptability, continuous fault ride-through andthree-times overload capability.
From its self-developed grid-forming verification platform, hardware-in-the-loop simulation certification by CEPRI, and CQC full-unit certification, to station-level on site validation by a third-party (DNV), Sineng has become the first in the industry to achieve a full-stack “true grid-forming” verification loop.
