World's First 100-MW Intelligent Grid-Forming Energy Storage Station in Qinghai Put into Operation

TapTechNews on June 20th, the world's first 100-megawatt-hour intelligent string-type grid-forming energy storage power station - The Golmud Lvneng 50-megawatt/100-megawatt-hour grid-forming energy storage power station in Qinghai has been officially put into operation recently.

The project is located in the photovoltaic industrial park of Golmud City, Haixi Mongolian-Tibetan Autonomous Prefecture, Qinghai Province, and was jointly developed by China Green Development Qinghai Branch and Huawei Technologies Co., Ltd. The construction scale of the project is 50 megawatts/100 megawatt-hours, which is composed of 50 2-megawatt-hour intelligent string-type battery cabins and 600 200-kilowatt grid-forming voltage source converters.

It is introduced that, different from the conventional grid-following energy storage power station which depends on the real-time voltage and frequency data of the power grid to adjust the output of the power station, the grid-forming energy storage power station adopts an intelligent photovoltaic storage generator solution, which can independently adjust voltage and frequency; after being connected to the grid, it can increase the proportion of new energy access in Qinghai Power Grid by 40%, equivalent to saving 21,450 tons of standard coal and reducing 53,480 tons of carbon dioxide.
