China News Service, Xining, March 9th, title: Golmud, Qinghai: The development of desert "green energy" is boundless
Author Sun Rui Li Shasha
In recent years, in the outskirts of Golmud City, Qinghai Province, in the hinterland of the Qaidam Basin, “big windmills” have rotated day and night, and rows of light blue solar panels have been shining, making this originally barren land change. It has to be vivid.
With its unique advantages, Golmud in the deep desert zone can be described as unlimited.
In the Luneng Haixi State Multi-energy Complementary Integration and Optimization Demonstration Base, the 50 MW tower molten salt solar thermal power generation project is particularly eye-catching.
The project not only fills the technical gap in domestic intelligent dispatching of wind and solar thermal storage and regulation, but also the world’s first multi-energy complementary technological innovation project integrating wind and solar thermal storage and regulation. After the project is completed, the yellow sand, blue sky and photovoltaic panels A special landscape between the sky is formed in the space, which also makes Golmud City and even Qinghai Province go wider and wider on the road of "new energy + multi-energy complementation".
A few days ago, in the control center of the base, the reporter saw the multi-energy complementary energy storage power station operation monitoring display screen, the battery is fully charged and standby, and it can output clean, green power at any time.
"Our energy storage power station is operating at full load, storing 100,000 kilowatt-hours a day, ensuring that clean and efficient low-carbon energy can be delivered to the country at any time." said Su Yue, deputy head of the photovoltaic power station of the Luneng Multi-energy Complementary Integration and Optimization Demonstration Base.
"The unique advantage of Golmud has brought huge room for development to our new energy companies. From barren sandy land to today's photovoltaic solar thermal industrial park, patches of photovoltaic panels and heliostats chase the light day by day. Some people call this place. It is'Sun City', I think it is worthy of the name." Zhu Ziguang said.
In recent years, 45 new energy companies have settled in Golmud City. They have continued to grow with the advantages of Golmud solar and wind energy, laying a solid foundation for the development of Golmud's new energy.
The city further optimized its energy structure, accelerated the construction of clean energy projects, achieved good results in the development of new energy, achieved good results in the development of new energy, the country's first batch of multi-energy complementary integration optimization demonstrations, and the third batch of "leaders" Major leading demonstration projects such as photovoltaic power generation application bases were completed and put into operation, which played a positive role in promoting the comprehensive utilization of clean energy and the reduction of clean energy electricity prices.
Located in the Qaidam Basin, Golmud is a key area for economic development in Qinghai Province and Haixi Prefecture. The new energy industry has outstanding development advantages and huge potential.
Golmud is rich in solar energy resources and is one of the regions with the most abundant sunlight resources in the country. The annual sunshine hours are between 3,200 and 3,600 hours, and the total annual radiation can reach 6,800-7,200 MJ/m2, which is the second highest value area in the country. , The average wind speed of the wind farm at a height of 70 meters can reach 6-7.1 m/s, and the average wind power density is 206.6-321.7 watts/m2.
Due to the vast land and sparse population in the Golmud area, the terrain is flat, the land is level, and the geological structure is stable, the good geographical advantages provide good land resources for the construction of new energy projects.
Golmud also has the advantage of power grids. 750 kV, ±400 kV, 330 kV, and 110 kV transmission grids have been formed in the territory. The grid structure has been gradually improved to provide a reliable guarantee for the transmission of new energy projects.
Meng Fanjun, director of the Golmud City Development and Reform Commission, said that in the future development, the city will take the creation of a demonstration city for comprehensive application of smart energy as a starting point, and strive to create a whole chain area for the construction, use and output of clean energy projects to achieve stable and stable clean energy power generation installations For healthy and steady growth, we will focus on improving and optimizing the energy structure, lay a solid foundation for energy security development, improve the level of coordinated development of energy, and build a modern comprehensive smart energy system featuring "green and low-carbon, economic and environmental protection, multi-energy complementary, and intelligent interconnection".
Meng Fanjun stated that Golmud plans to add 26.2 million kilowatts of non-aqueous renewable energy grid-connected installed capacity during the "14th Five-Year Plan" period, focusing on accelerating the second clean energy delivery channel, pumped storage, and key experiments of advanced energy storage technology in Qinghai Province. The construction of major projects such as laboratories, energy revolution demonstration bases, hydrogen energy application demonstration cities, nuclear heat and power generation, wind, wind and nuclear multi-energy complementation, etc., has built an important national "new energy industry base" and "national clean energy demonstration province" for Qinghai Province. "Energy Revolution Demonstration Province" has made positive contributions.
