Chinanews, Urumqi, January 14th (Yan Wenlu Yuyan Chunqiang Jiqiang) On January 1, 2023, the wind power generation capacity of Xinjiang power grid was 36.82 million kwh, and the photovoltaic power generation capacity was 37.34 million kwh, achieving "zero curtailment of wind and zero curtailment of light". ", Wind and solar energy are fully connected to the grid and consumed in full.

　　Xinjiang has abundant new energy resources. As a large-scale oil and gas production, processing and storage base determined by the state, a large-scale coal and coal chemical industry base, a large-scale wind power base, and a national energy resource land channel, how to realize the "double carbon" goal based on It is the most urgent problem in Xinjiang to make full use of the advantages of resource endowment and promote the development of new energy industry.

In 2022, Xinjiang's electric power sector will explore paths for the high-quality development of Xinjiang's new energy industry through continuous improvement and reinforcement of the grid structure, good integration of new energy into the grid, and innovation in new energy consumption models.

Let new energy have a "road" to go

　　As of January 3, 2023, the 750 kV power transmission and transformation project in Shanshan (Tuha) has been in continuous and safe operation for eight and a half months.

This is an ultra-high-voltage power grid construction project put into operation in Xinjiang in 2022. It has opened up new energy transmission channels in Shanshan and Shisanjianfang areas, and has increased Shanshan's new energy acceptance capacity several times, from 300,000 kilowatts to 2 million kilowatts.

　　Open the distribution map of my country's energy resources, the reverse distribution of energy resources and demand is vivid on the paper.

The western energy base is generally 1,000-3,000 kilometers away from the eastern and central load centers.

As the most northwest of China, Xinjiang has a large number of "oil basins", "gas fields" and "coal seas" among the mountains and oasis Gobi, and it is also a "rich mine" of new energy such as solar energy and wind energy.

Once upon a time, there were endless discussions about energy delivery here.

Building roads has become a common consensus among the people.

The answer given by the State Grid Corporation of China is the construction of the "Xinjiang power transmission" channel, so that Xinjiang energy has a way to go.

　　Since the State Grid Corporation of China launched the "Xinjiang power transmission" work in 2010, it has successively built the 750 kV first and second channels of the main grid interconnection between Xinjiang and Northwest China, the Changji-Guquan ±1100 kV UHVDC transmission project, the Hami South- Zhengzhou ±800 kV UHV DC transmission project "two AC and two DC" outgoing channels.

At the same time, it continued to improve the core backbone network structure, accelerated the construction of power grids at all levels, and built 25 750 kV substations in Xinjiang, with a transformation capacity of more than 73 million kVA, and 750 kV transmission lines reached more than 8,700 kilometers, 750 kV The kilovolt power grid covers 14 prefectures in Xinjiang, and the ability to optimize the allocation of resources in Xinjiang has been significantly improved.

So far, Xinjiang has formed a main grid structure of "four ring networks for internal supply and four channels for external transmission". The external transmission capacity of Xinjiang power has reached 25 million kilowatts, and the external transmission area covers 20 provinces and cities including Chongqing, Jiangsu, Sichuan, and Hunan.

As of 2022, Xinjiang Power's external power transmission has accumulated 125.66 billion kWh, and new energy external power transmission accounts for more than 30%, playing an active role in ensuring the safe and reliable supply of energy across the country and preventing and controlling air pollution.

Let new energy no longer "wait for work"

　　On December 27, 2022, in Shisanjianfang, Hami, Xinjiang, the State Grid Hami Power Supply Company organized personnel to conduct the final inspection of the new energy station that will be connected to the grid.

Here, a mega-kilowatt-level wind power base is being built, and the Gobi desert, which can't be seen at a glance, presents infinite "vitality" because of the vertical and horizontal wind turbines.

　　After experiencing the upsurge of "road" construction, Xinjiang New Energy has shown a "blowout" type of development.

As of the end of December 2022, the installed capacity of new energy such as wind power and photovoltaic power generation in the Xinjiang power grid has reached 40.655 million kilowatts, accounting for 36.09% of the total installed capacity of the Xinjiang power grid. The installed capacity ranks among the top in the country and the first in Northwest China.

　　Such a huge amount was unimaginable in the past.

In order to actively promote the development of new energy in Xinjiang, State Grid Xinjiang Electric Power Co., Ltd., on the one hand, is making full use of the climate differences and time differences of load peaks in various regions of Xinjiang to increase the utilization hours of new energy units in each region, so as to realize the In Xinjiang, day and night, seasons complement each other, wind and electricity complement each other, so as to maximize the utilization and optimal allocation of new energy.

At present, the new energy utilization rate of Xinjiang power grid has increased to 94.6%.

On the other hand, adhere to the priority scheduling of new energy power generation, make every effort to ensure that new energy projects can be "combined as much as possible", smooth the green channel for grid connection projects, promote the simultaneous planning, construction, and commissioning of supporting grid projects and new energy projects, and provide the whole process One-stop service to ensure that new energy projects are "connected to the grid immediately after completion" and fully support the development of new energy industries.

　　In addition, more than 10 kinds of algorithms such as artificial intelligence (AI) have been introduced to predict the power of new energy, so that new energy power generation has a "weather forecast", and the output and power of new energy in the future can be grasped at any time, further promoting the consumption of new energy. accept.

Implement the "Plan to Improve the New Energy Price Mechanism in Our Region" issued by Xinjiang, and provide subsidy policies from the province to inject a "stimulant" into Xinjiang's realization of the "double carbon" goal.

Let the domestic consumption and external delivery of new energy "go hand in hand"

　　From September 26th to 27th, 2022, Xinjiang participated in the first batch of inter-provincial green power transactions, trading 11.5 million kWh of green power, opening up a "new channel" for the consumption of Xinjiang's abundant renewable green energy, and also for more Large-scale Xinjiang green electric energy has entered millions of household electrical appliances companies across the country and pressed the "start button".

　　During the summer peak in 2022, State Grid Xinjiang Electric Power will continue to expand the scale of Xinjiang power transmission, converting abundant wind, light, and coal resources into electric energy for transmission to distant places.

In the whole year of 2022, among the 125.66 billion kWh of Xinjiang power transmission, new energy transmission will account for more than 30%.

　　It is necessary to let the new energy get on the "net", but also let the new energy get off the "net".

Over the years, Xinjiang Electric Power has always been based on the "two markets" inside and outside Xinjiang, and has continued to expand the space for new energy consumption by increasing the marketization of electricity and deepening the substitution of electric energy, and "go hand in hand" with the domestic consumption and external delivery of new energy.

　　In Xinjiang, actively promote the flexibility transformation of thermal power units in Xinjiang, deepen the coordinated control of wind, water and fire, and explore models such as coal-fired self-provided power plants and new energy green alternative transactions, cross-regional surplus new energy spot transactions, and peak-shaving auxiliary service markets.

Combining regional and industry development, steadily and orderly promote electric energy substitution in industry, construction, transportation and other fields, and apply combined technical means such as "electric energy substitution + demand response" and "new energy + electric energy substitution" to serve energy conservation and carbon reduction on the consumption side, and promote regional low-carbon develop.

Outside Xinjiang, on the basis of fully ensuring the proportion of new energy in the "Xinjiang power transmission" channel, combined with Xinjiang's "strong during the day and weak at night" periodical transmission characteristics, make full use of the remaining capacity of the transmission channel to organize "Xinjiang power transmission" "Help power supply in other provinces, help electricity companies broaden their carbon emission reduction paths, help them transform and upgrade, and achieve low-carbon and zero-carbon sustainable development.

　　Today, batches of new energy projects are under construction in Xinjiang, and the silver wires of the power grid are connected to the four directions, continuously sending clean energy to various places.
