What is the trend of wind resources in the field of wind power?

On the endless Gobi, more than 30 wind turbines stand between heaven and earth. Except for the power station under construction, there is no one near this wind farm under construction, and even vegetation is extremely rare. The relevant person in charge of Longyuan Bakun Wind Power Generation Co., Ltd., the operator of the wind farm, pointed to the motionless generator blades and said that in a few months, it will be able to run and generate electricity here. This wind farm with a total installed capacity of 49,500 kilowatts is only the first phase of Long Yuan's wind power project in Santanghu, Hami, Xinjiang. When it comes to the development of wind power in Hami, Hami's leaders cannot hide their pride. In the regional development planning, wind power generation has become an important part of its future development. They even shouted the development slogan of "unlimited scenery, very happy", in which "unlimited scenery" refers to solar power generation (/) and wind power generation. Only Hami attaches importance to the development of wind power. In the Twelfth Five-Year Plan for Renewable Energy released by the National Energy Administration of China a few days ago, Hami also ranks among them and becomes one of the important regions in the future. In the new national plan, Hami, Xinjiang, Hebei, eastern Inner Mongolia, western Inner Mongolia, Jiuquan, Gansu, Jilin, Heilongjiang, Jiangsu and Shandong coastal areas will become 10 million kilowatts of wind power bases to be built. Xinjiang has a unique advantage in developing wind power. According to statistics, the total amount of wind energy resources in Xinjiang is about 872 million kilowatts, of which the exploitable area is nearly 6.5438+0.5 million square kilometers, and the total amount of onshore wind energy resources in Xinjiang accounts for about 40% of the national total. This time, Hami has become a major wind power base for key construction, which is undoubtedly a new opportunity for the development of wind power in Xinjiang. While Hami gradually began to develop wind power, the development of wind power in China also ushered in a new task. A few days ago, the Twelfth Five-Year Plan for Renewable Energy issued by the National Energy Administration pointed out: "By 20 15, the cumulative installed capacity of grid-connected wind power will reach 10 billion kilowatts, and the annual power generation will exceed 19 billion kwh, of which the installed capacity of offshore wind power will reach 5 million kilowatts, basically forming a complete and internationally competitive Haoxin reducer equipment. In addition, the plan also sets a longer-term goal. The plan puts forward that "by 2020, the cumulative installed capacity of wind power connected to the grid will reach 200 million kilowatts, and the annual power generation will exceed 390 billion kilowatt hours, of which the installed capacity of offshore wind power will reach 30 million kilowatts, and wind power will become an important power source of the power system". Compared with the current depressed domestic wind power market in China, in the eyes of many people, the wind power target in the new plan seems to be the most uncertain target. It is understood that as early as 20 1 1 year, the domestic wind power enterprises in China have lost their popularity, and most of them have experienced a decline in performance. This situation has continued until this year, and some of them eventually closed down due to lack of strength. "Due to the sluggish industry, many peers in the industry have resigned in disguise, and now the industry is really depressed." A staff member engaged in the fan manufacturing industry told the reporter of Science News. "The biggest problem at present is that after the fan runs in the future, the electricity generated cannot be sent out." The person in charge of the wind power base in Santanghu Industrial Park looks grim. "If the grid connection problem is solved, let alone 1 100 million kilowatts, higher wind power targets may also be achieved." Shi Minjun, deputy director of the Virtual Economy and Data Science Research Center of China Academy of Sciences, said this. Whether in the eyes of operators or experts, the biggest problem of wind power generation at present is grid connection, which is also the biggest uncertain factor to complete the planned goal. In this regard, even the person in charge of the State Grid agreed. Shu Yinbiao, deputy general manager of State Grid, publicly told the media: "In the years of rapid development of wind power, the power grid is in the key link of wind power development and has always been the focus of various contradictions." The new plan proposes to strengthen wind power development in inland resource-rich areas, strengthen the evaluation, development and construction of wind energy resources in inland areas outside the "Three North" and encourage decentralized grid-connected wind power development and construction. At present, the main battlefields of wind power generation in China are still located in China's "Three Norths" and coastal areas, but these areas are often not the center of power consumption, so power transmission needs to be carried out through the power grid. Because of the instability of wind power itself, the power grid is unwilling to accept wind power. This has caused the embarrassing situation that the wind power station can't generate electricity at present. Grid connection not only brings difficulties to operators, but also challenges to wind turbine manufacturers. The person in charge of Goldwind Technology Company told the science journalist that the difficulty of grid connection caused by the disharmony between wind power development and power grid construction has become the main bottleneck at present. Based on the long-standing problem of grid connection, as early as several years ago, relevant departments and institutions put forward slogans such as developing smart grid. In Shi Minjun's view, in addition to solving the technical problems of grid connection, it is more important to consider policy support and institutional change. "To make the power grid willing to absorb wind power, besides technology, we need to think of some ways, such as giving government subsidies. The focus is on solving the problems of the old market and solving the problems of institutional mechanisms. " He said that it is very important to make cooperation between departments through institutional adjustment. In the enterprise's view, with the promulgation of the Twelfth Five-Year Plan for Renewable Energy, the State Grid clearly stated that 1 100 million kilowatts of wind power will be connected to the grid during the Twelfth Five-Year Plan period, and 200 million kilowatts of wind power will be connected to the grid by 2020. It is believed that the difficulty of wind power access will be gradually solved. "As a manufacturer, we should increase research and development, develop grid-friendly units and products that adapt to the power grid, promote grid-connected wind power, and constantly optimize product quality and strengthen service capabilities to ensure the full life cycle benefits of wind farm projects invested by customers in 20 to 25 years." The person in charge of Goldwind Technology expressed his expectation for this. "Although this industry is currently depressed, it is still very promising. "The aforementioned fan manufacturing practitioners who did not want to be named told the reporter of Science News. In his view, on the one hand, the current problem of wind power industry is the obstacle of power grid; On the other hand, it is still in the technology of fan manufacturing. In recent years, good news about the development of high-power wind turbines and various new types of wind turbines has been coming: the manufacturing capacity of wind power equipment has been rapidly improved, and the manufacturing capacity of wind turbines and main components with various technical types and specifications above 1.5 MW has basically met the development needs of onshore and offshore wind power, but these achievements do not mean that the manufacturing technology of wind turbines in China is completely mature. "There is still a certain gap between domestic manufacturers and world-class major competitors, such as the systematicness, quality and efficiency of our R&D and management. Technological innovation needs to be based on long-term technology research and development accumulation and will not happen out of thin air. " The relevant person in charge of Goldwind Technology said this. The person in charge said that the technical development of wind power in the future will mainly focus on several directions: First, the pursuit of electricity costs. The so-called kilowatt-hour cost of wind power is the total cost per kilowatt-hour of electricity produced by wind power developers or operators. The lower the kilowatt-hour cost, the more energy producers and consumers will benefit. Second, the pursuit of smarter. That is, smart grid and energy storage technology are combined to intelligently manage wind farms according to grid demand and wind energy. Third, we should be friendly, such as community friendly, environment friendly and grid friendly. In addition, we should continue to expand the application scope of wind power, so that wind power can be better linked with other industries, such as hydrogen production, ammonia production and seawater desalination. In recent years, the government of China has put forward a series of development standards and specifications for the quality problems of the fan industry, among which the technology and quality of fans are also impressively listed.
