The wind rises and the sand flows everywhere, and the sand pressure houses and people move away. The Kubuqi Desert, which was once described, has now turned into a deep blue sea shining with gold, which shows the outstanding achievements of China in controlling desertification. Moreover, the scale of large-scale scenic base in Shage wasteland area has reached 450 million kW, equivalent to the installed capacity of 20 Three Gorges hydropower stations. So why do these scenic bases prefer "no man's land", and how does it control sand?
It is about to talk about the stereo comprehensive photovoltaic sand control measures of power generation, planting under plate and breeding between plate. For example, the Kubuqi energy base in Mengxi planted sand willow, flower sticks and other sand grass between the 400w solar panels. The solar panels can shade the light and wind for these grasses, and the water from cleaning the solar panels can also be used for irrigation. These grasses can not only play the role of windbreak and sand fixation and reduce water loss, but also feed livestock and poultry.
Or even to develop tourism or cash crops. For example, Dalat Banner scenery power base, with 196,000 pieces of photovoltaic panels formed a horse pentium pattern, has become a network red attractions, attracting a lot of tourists to come to see the card, and also in the photovoltaic array between the planting of smut, astragalus and other economic forest.
According to relevant data, the construction of a 1 million kw photovoltaic sand control project in the desert can save 440,000 tons of standard coal, and the windproof and sand fixation area can reach 4,000 hectares, which is equivalent to planting 640,000 trees. Isn't this the king of sand control without problems? Then we need to know, photovoltaic power generation is instant generation, there is still instability, how to ensure that these photovoltaic power can operate in high quality?
In fact, these problems countries had considered early, take the Gansu project as an example, it is the first "scenery fire storage integration" power high-voltage project in our country, in the early stage of the construction, according to total installed capacity, stored energy of 10%, on the basis of traditional electrochemical energy storage, and various forms of compressed air stored energy and pumped storage, etc. This means that it can transmit the electricity generated by wind power, photovoltaic power and thermal power together with the stored power to Shandong through UHV.
In addition, China, as a pioneer in carbon neutrality, will vigorously promote the construction of wind power photovoltaic base in Shago Wasteland in 2022 to ensure that the proportion of non-fossil energy consumption will reach 20% from the current 16.6% by 2025. We also look forward to achieving carbon neutrality as soon as possible.
