However, because it is difficult to grow crops and cash crops, many deserts in China are in an unusable state. The extreme temperature in the desert can reach 70-80 degrees, and the sunshine resources are very rich, which has the natural advantage of building a photovoltaic energy base. Then, if these desert areas are used to lay a large area of solar power stations, and the natural properties of desert areas are used to form a state of efficient power generation, can they be better recycled? This idea is actually feasible, but it has no great advantage in cost and is technically difficult.
As we all know, the deserts in China are located in remote areas. For example, in a few areas such as Xinjiang and Inner Mongolia, although they cover a large area, the transportation is inconvenient, and they are hundreds of kilometers away from the nearest city. Take Taklimakan Desert as an example, if a large-scale photovoltaic power generation base is established in this desert, its power generation will be very huge. Therefore, how to transport these electric power to cities that need it urgently has become a problem that must be solved.
About 700 kilometers in the Taklimakan Desert is Lanzhou City, Gansu Province, China. According to the fact that China UHV technology can transmit 3500km, the power transmission at this distance is obviously not a problem. (The transmission distance from Zhundong to southern Anhui, the longest UHV transmission line in China, is more than 3,300 kilometers), so if large-scale solar power plants are arranged in desert areas, only one UHV transmission line is needed to solve the transmission problem. Of course, the construction cost of such a high-standard transmission line in a barren area is still quite high.
It is also very difficult to build a large photovoltaic power station in the desert, because it is necessary to build a large photovoltaic power station in the barren desert area, so the transportation of various equipment and supporting facilities required for the power station has become a problem. Located in Taklimakan Desert of Tarim Basin, the nearest city is Kashgar, Xinjiang. However, due to the small electricity consumption of residents in this city, it is not cost-effective to build a photovoltaic power station of this scale. Therefore, to build a large power station in the desert, it is necessary to send it to the eastern region.
The new energy vehicle project vigorously promoted by China is very important for electric power.
The demand for force is enormous. Therefore, in Xinjiang, it takes a very large fleet and relatively high labor cost to transport the produced photovoltaic panels and power station equipment to the middle of the desert for photovoltaic power station construction. Therefore, the construction of such a large project may still require state investment to solve many problems in the construction process.
Building such a large photovoltaic power generation project in the desert area of Xinjiang requires assembling a very large transportation team, a large number of photovoltaic power generation equipment and supporting facilities, and a very large manpower to fully build it. It is difficult to do it without sufficient funds and courage. Therefore, if G wants to build such a power station in the desert area, it must rely on the national strength to gather more resources and strength, and it is impossible without hard work.
To solve the interference of weather factors, it is necessary to build such a large-scale project in desert areas. The first thing to face is the test of the weather. Although desert areas have the natural advantages of photovoltaic power generation, they are sometimes easily affected by sandstorms. It is not impossible if dust is blown to the surface of the photovoltaic panel or even the whole photovoltaic panel is overturned. To solve this problem, a large windbreak forest must be built around the photovoltaic power station, which can effectively reduce the damage of sandstorm to photovoltaic power station. However, the construction of a large windbreak is obviously a very large expenditure, and it is difficult to form such a large windbreak in desert areas.
Conclusion: In the case of strong power demand in East China, solar power generation projects are obviously more time-sensitive than wind power generation projects to reduce the use of thermal power and make up for the water and electricity gap. Compared with intermittent wind power generation, solar power generation has the characteristics of stable power generation, cleanliness and high efficiency, and easy energy storage. Therefore, it is necessary to build large-scale photovoltaic power plants in desert areas where many projects cannot be carried out.
Although it is not difficult to realize technically, cost is also an important factor to consider. Under the national grand strategy, China's power demand will only increase. I hope that in the near future, China can build more clean and efficient photovoltaic power generation projects in more areas to benefit the society!
