Xinjiang Economic Highlights 丨 Strong Channel Green Energy Xinjiang Electricity Support 15 provinces and cities

Pomegranate/Xinjiang Daily reporter Chen Qiangqi

Since the beginning of this year, high temperatures and rains in many places across the country, continuous power gaps in East China, Central China, and southwest, and the national power supply and demand situation has been tense. Facing the power supply demand for other provinces and regions and cities in China, Xinjiang, as the country's "three bases and one passage", overcomes its own electric load and has repeatedly innovated many high challenges. Delivery scale.

In the first 8 months, Xinjiang's out -of -the -ware electricity volume was 85.978 billion kilowatt -hours, and the number of cross -district out -of -district out -of -district electricity delivery in 26 provinces and regions operated by State Power Grid Co., Ltd. ranked 3rd in a record high. This transforms the rich resources such as coal, wind, and light into power resources, and strongly supports the power supply of 15 provinces and cities including Jiangsu, Shanghai, Hubei, and Chongqing.

Improve channels for delivery capabilities

On September 13th, at ± 1100 kV Changji exchange stations, the party branch secretary and deputy webmaster of the station, Gao Xinlong, and colleagues checked the production plan to ensure that the production tasks were completed as scheduled. This is the delivery of the fourth Xinjiang Power Delivery Channel -Changji -Guquan ± 1100 kV high -voltage DC transmission project (hereinafter referred to as Jiquan DC). Essence

Since the beginning of this year, this conversion station has conducted two conveying power increases in order to meet the electricity needs of other provinces and regions and municipalities in China.

"In June, the conversion station increased the conveying power from 9 million kilowatts at the beginning of the year to 10 million kilowatts. On August 5, due to the increase in high temperature power consumption in other provinces and regions and cities in China, we increased to 11 million kilowatts." Gaoxinlong said Jiquan DC has not had a high load for so long before. This time the conveying power improvement is not only a test of engineering quality, but also a big test for power scheduling and operation and maintenance personnel. Judging from the final results, the project's he quality and quantity have completed the outlook and electricity mission, proved China's leading level in the world's power industry. Jiquan DC daily transportation power can reach 241.9 billion kWh, which has become the largest DC project in the world in the world.

Statistics show that the total scale of Xinjiang Power's delivery has been increased from 18.4 million kilowatts in 2019 to 20.4 million kilowatts this year, which is a record high of the history of Power. Among them: Jiquan DC conveying power is 11 million kilowatts, Hami South -Zhengzhou ± 800 kV high -voltage DC transmission project (hereinafter referred to as Ha Zheng DC) conveying power of 6 million kilowatts, Xinjiang and Northwest main network network 750 kV The conveyor power is 3.4 million kilowatts. This is exactly the "two intercourse and two straights" delivery channel structure built by Xinjiang.

Expand the efficiency of delivery of Xinjiang electricity

The Xinjiang Delivery Channel is connected to the Power Market in the Xinjiang and Jiangxi Internal and Jiangxi. How to improve the efficiency of transportation scientific and efficiently, it tests the scientific scheduling and market development capabilities of the power grid.

"We use the advantages of resource allocation of the unified power market in the country, improve the cross -provincial telegram negotiation mechanism, and further improve the efficiency of Xinjiang's transmission." The mechanism, that is, the long -term protocol of the long -term and long -term protocols of the channel supporting power supply, the annual agreement of the power aid of the Power Aid, and the market -oriented power delivery contract with the electrical negotiation mechanism, explore the benchmark price of the establishment+dynamic adjustment mechanism of upper and lower floating electrical prices Essence

State Grid Xinjiang Electric Power Co., Ltd. also flexibly adopts a new model of "Month (Month (Multi -month)+Monthly+Weekly" Power Aid Transaction Organization, shorten the transaction organization cycle, encrypted transaction organization batches, and orderly release power supply delivery capabilities, expands the ability to expand The scale of Xinjiang Power delivery.

In 2016, Xinjiang launched the "Power Aid+Marketing" cross -regional transmission. Since its launch, a total of 120.3 billion kilowatt -hours of Aid Aid Agreement has been signed, of which the scale of the agreement in 2022 reached 23 billion kWh, which was 6.5 times in 2016. Electricity aid in Xinjiang has become an important part of industrial aid and Xinjiang Delivery.

In the background of the national unified power market, through continuous innovation organizational trading models, the scope of power transactions has been successfully expanded, which can not only transform Xinjiang's resources into economic advantages, but also meet the power consumption needs of other provinces, autonomous regions and municipalities.

Since June, Xinjiang Power Grid has supported 55 times of China East, Central and Chongqing Power Power Grid through cross -district and provincial power transactions, supporting 33.9 billion kilowatt -hours. The maximum single -day out -out electricity delivery volume reached 447 million kilowatt -hours, a historical record, accounting for more than 40%of the largest single -day out -out power delivery ratio in the northwest region, ensuring that the amount of electricity in Xinjiang "should be delivered".

Optimize and increase delivery green energy

On September 14th, in the Barry Kazakh Autonomous County, Hami City, the 134 typhoon firms at the Santang Lake Second Windfield of Xinjiang Branch of China -Guangzhou Nuclear New Energy Investment (Shenzhen) Co., Ltd. are running safely.

The wind farm is a supporting new energy electric field for Harchi DC. The total installed capacity is 200,000 kilowatts, and the average annual power generation is exceeded 500 million kilowatt -hours.

"In August, the amount of grid electricity on our electric field increased by 11%year -on -year." Guo Yonghui, the director of the wind farm, said that since August, in order to ensure the supply of DC power in Harbin, to meet the demand for electricity consumption in Central China, the electric field overcomes the impact of the epidemic. All employees at the production site adhere to their posts and make every effort to ensure the safe and reliable operation of the equipment.

Kazakhstan DC is the country's first high -voltage project to carry out a large -scale high -voltage project from the northwest of fire, wind, and light., Can directly drive 100 billion yuan in investment in Xinjiang.State Grid Xinjiang Electric Power Co., Ltd. plans to promote the flexible transformation of the Kazakhstan DC coal electrical unit to further increase the proportion of new energy consumption of channel delivery.Harchi DC was delivered in Hami City. The city has built a million kilowatt -level photovoltaic power generation base and a tens of millions of kilowatts of wind power bases. It is actively promoting the construction of the "integrated integratedness of the source network".

"With the in -depth promotion of the" three bases and one channel "construction in Xinjiang, we have also continuously improved the new energy of Xinhe Power Delivery and the priority dispatch mechanism of new energy by accelerating the approval of new energy reception, promoting supporting facilities, and strengthening the new energy priority dispatch mechanism.Bi. "Wang Xingang said.

As of the end of August, Xinjiang's new energy installation scale reached 38.07 million kilowatts, and the cumulative delivery of new energy accounts for more than 30%of the total out -of -electricity delivery.
