China Energy Storage Network News: In recent years, the utilization rate of clean energy sources such as photovoltaics and wind power has continued to rise, but the constraints on their frequency of use and ability to be integrated into the power grid have always been concentrated on the level of energy storage. How to solve the energy storage problem is an important issue in vigorously promoting "carbon peak carbon balance".
Guazhou County, as "the county with the largest wind power installed capacity in the country", is known as the "World Wind Bank". In recent years, Guazhou County has relied on its abundant new energy resources to vigorously develop new energy power generation enterprises. At the same time, it has made full use of the favorable terrain of Xinjiang, Qinghai, and Gansu power grid hubs to strengthen power grid construction, centrally open power transmission channels, and strengthen the power supply side. , construction and layout of grid-side and user-side energy storage projects to promote high-quality and large-scale development of new energy storage.
Huantai Guazhou Beidaqiao Baiyang 100MW Wind Power Project is a representative local energy storage power generation project. Not far from the project station, Huantai Energy Storage Power Station has been connected to the grid.
Looking from a distance, the energy storage components of the flow battery + stack are arranged side by side, and a huge electrochemical energy storage matrix comes into view. "Our energy storage power station project, through assembly and system integration with vanadium electrolyte storage tanks, is finally integrated into a 15MW/60MWh all-vanadium flow energy storage system. After the entire energy storage power station is completed, it will become the largest power supply in the country. Side all-vanadium redox flow energy storage power station." said Li Wenkui, general manager of Huantai Industrial (Guazhou) Co., Ltd.
"The vanadium battery energy storage power station is like a giant 'power bank', which can play the role of peak-shaving and valley-filling in new energy power. It stores electricity during low periods of electricity consumption and releases electricity during peak periods of electricity consumption to supplement electricity consumption. We can make up for the intermittency and volatility of power generation from renewable resources such as solar energy and wind energy," Li Wenkui said.
At present, the Guazhou Line has built one 60MW/240MWh lithium iron phosphate grid-side large-scale energy storage power station; 9 2-hour lithium iron phosphate power-side energy storage power stations, with a total installed capacity of 157MWh; in One 100 MW solar thermal energy storage power station is under construction, equipped with a 6-hour molten salt heat storage system; one 500 MW/1000 MWh shared energy storage power station is under construction, and 500 MW/1000 MWh shared energy storage power station has been registered One energy storage power station and one all-vanadium flow 125 MW/500 MWh energy storage power station.
"Guazhou County has always cultivated the new energy industry as the first industry, based on the advantages of new energy resources, accelerating the construction and layout of power supply side, grid side, and user side energy storage projects, and building a 'wind, solar, thermal and hydrogen storage multi-energy complementary, source Grid-load-storage integration develops a green energy system," said Wu Hongwei, deputy director of Guazhou County Energy Affairs Center.
The optical storage industry is moving towards "light". In recent years, Guazhou County has focused on the all-round layout of "generation, transmission, storage, consumption and manufacturing", making efforts across the entire chain, overall planning, and coordinated advancement. Relying on the advantages of the regional wind power industry, Guazhou County has made every effort to promote the construction of wind and photovoltaic projects, and coordinate the promotion of peak-shaving power supplies and output power grids. , equipment manufacturing, electric energy consumption and energy storage research and development and other supporting industries, embarking on a "splendid" road of high-quality development by "chasing the wind and the sun".
