Huawei-Enabled World’s First 100MWh Grid-Forming Energy Storage Station Proves Resilience in Pioneering Test

Huawei’s involvement has led to the completion of the world’s first artificial short-circuit disturbance test on a 100MWh grid-forming energy storage station, conducted by Qinghai Electric Power Research Institute in collaboration with Huawei and Luneng New Energy.

As the world’s first 100MWh intelligent string-type grid-forming energy storage station, the 50MW/100MWh grid-forming energy storage station in Golmud, Qinghai, operated by Luneng, was officially put into operation on May 31. This artificial short-circuit disturbance test is one of a series of tests aimed at verifying the performance of grid-forming energy storage units and stations in response to grid events.

The 50MW/100MWh grid-forming energy storage station was co-developed by Qinghai Branch of China Green Development and Huawei Technology Co., Ltd. It adopts an intelligent photovoltaic and energy storage generator solution, featuring 3 times the reactive current, a 5ms inertia startup time, and oscillation suppression in a wide range of 0.1Hz to 100Hz. By reconstructing “voltage, frequency, and power angle” stability, it enables new energy to have the same “stable” characteristics as traditional generators, increasing the new energy integration ratio by 40%.

The two 35kV artificial short-circuit disturbance tests were conducted under two different operating conditions: charging state of the grid-forming control mode of the energy storage system and discharging state of the grid-forming control mode + charging state of the grid-following control mode. These tests comprehensively verified the frequency and voltage regulation capabilities of the grid-forming energy storage station under different voltage levels of the power grid in the context of “high voltage and high current” grid characteristics.
