At noon in the Gobi Desert, the photovoltaic panels are connected into a deep blue, the wind turbines are running happily, and there is too much electricity to use up; In the evening, the wind stopped, the output dropped sharply, and the peak of urban electricity consumption had just begun to rise. Stably aligning these two ends are energy storage power stations. As of the end of September, the installed capacity of new energy storage in Xinjiang power grid reached 25.115 million kilowatts, with an additional 4.964 million kilowatts added during the year, ranking first in the country in terms of installed capacity.

As a national energy and resource strategic guarantee base, Xinjiang is accelerating the construction of the Shage Wilderness Base, with its scenery becoming more and more extensive, and its temperament of eating by the weather becoming more and more obvious. The synchronized layout of diversified energy storage is equivalent to equipping the power grid with giant power banks, smoothing out the randomness and volatility of wind and solar power output, and enabling the generation, storage, and stable transmission of green electricity. Nowadays, an industrial system has been formed for the coordinated development of multiple technological routes such as lithium iron phosphate, vanadium flow, sodium ions, flywheels, supercapacitors, and compressed air. The technology types are complete and the application scenarios are rich, providing stable, reliable, and diverse regulatory support for large-scale new energy grid integration and consumption.

How busy these power banks are, the numbers are the clearest. In 2025, the cumulative charging capacity of new energy storage in Xinjiang's power grid will reach 9.1 billion kilowatt hours, a year-on-year increase of 103%, and the equivalent utilization hours will be 1733 hours, an increase of 44 hours from the previous year. From January to September this year, the charging capacity was 10.71 billion kilowatt hours, the discharging capacity was 9.0 billion kilowatt hours, and the energy storage utilization hours were 1163 hours, of which the independent energy storage utilization hours reached 1361 hours. Valley filling peak release, move the wind and light that may be abandoned to the most needed moment. The market side synchronously paves the way, and the diversified revenue model of capacity compensation, electricity trading, and auxiliary services enables energy storage to be built and converted.

The power grid has a backbone

On a larger scale, new problems follow. The traditional power grid relies on the inertia of the rotors of thermal power and hydropower units, like a large flywheel to suppress frequency fluctuations; The higher the proportion of new energy, the fewer flywheels, and the easier it is for the power grid to collapse. Grid based energy storage allows the inverter to simulate a synchronous generator, actively establish voltage and frequency, output inertia, damping, and short-circuit current, and transition from following the grid to supporting it.

This is the key to ensuring the safe and stable operation of the high proportion new energy grid in Xinjiang. At present, the installed capacity of grid type energy storage in Xinjiang has reached 6.61 million kilowatts, ranking among the top in the country. Xinjiang has comprehensively improved the short-circuit support capability of the power grid by operating 99 distributed phase-shifting cameras, 9 grid type energy storage units, and 10 grid type static reactive power generators. State Grid Xinjiang Electric Power has also established an empirical system for grid construction equipment, taking the lead in issuing technical specifications and leading the preparation of multiple national and enterprise standards, accumulating engineering experience into industry rules.

From installing too much to using it well

The value of energy storage ultimately depends on the destination of each kilowatt hour of green electricity. The new energy storage industry in China is accelerating its agglomeration towards the northwest wind and solar resource rich areas, with Xinjiang becoming the core growth region of the country; The Gobi Green Power is transmitted to the eastern and central regions through the ultra-high voltage channel, and the more stable the energy storage, the farther it can be transmitted.keywords:New energy information network、keywords:Energy storage industry

State Grid Xinjiang Electric Power continues to play a role in energy storage regulation, accelerating the grid connection of 2 million kilowatts of new energy storage projects in 9 regions, increasing the proportion of grid construction and long-term energy storage, and promoting efficient power generation and utilization of new energy. From comparing who can install more, to comparing who can adjust accurately and use it well, Xinjiang is transforming its resource advantages into systematic capabilities. In the lamp that lights up in the evening, perhaps there is a ray of sunshine or a gust of wind left by noon.Editor/Yang Meiling
