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 the vegetation is extremely scarce. The relevant person in charge of Longyuan Barkun Wind Power Generation Co., Ltd., the operator of the wind farm, pointed to the motionless generator blades and said that it will be able to run and generate electricity here in a few months. The 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 and happiness", in which "unlimited scenery" refers to solar power generation (/) and wind power generation. Only Hami attaches importance to the development of wind power generation. In the Twelfth Five-Year Plan for Renewable Energy released by the National Energy Administration of China recently, 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 unique advantages in developing wind power generation. According to statistics, the total amount of wind energy resources in Xinjiang is about 872 million kilowatts, of which the exploitable area is nearly 65.438+0.5 million square kilometers, and the total amount of onshore wind energy resources in Xinjiang accounts for about 40% of the whole country. This time, Hami has become a key large-scale wind power base, which is undoubtedly a new opportunity for wind power development in Xinjiang. While Hami gradually started 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 exceed19 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. In addition, the plan also sets a longer-term goal. It is planned that "by 2020, the cumulative installed capacity of grid-connected wind power 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 in the power system". Compared with the current depressed domestic wind power market, 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, domestic wind power enterprises have lost their popularity, and most of them have experienced a decline in performance. This situation continued until this year, and some of them eventually closed down because of their strength. "Because of the industry downturn, 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 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-connected 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 these 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 the development of wind power 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 battlefield of wind power generation in China is still located in China's "Three Norths" and coastal areas, but these areas are often not power centers, 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 current wind power station generates electricity but cannot send it out. 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 reporter of Science News that the difficulty of grid connection caused by the uncoordinated development of wind power and power grid construction has become the main bottleneck at present. Based on the long-standing problem of grid connection, as early as a few 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, we need to think of some ways besides technology, such as subsidizing the government. The key point is to solve the problems of the old market and solve 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 introduction 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 grid connection will be gradually solved. "As a manufacturer, it is necessary to 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 life cycle benefits of wind farm projects invested by customers for 20 to 25 years." The person in charge of Goldwind Technology is full of expectations. "Although the industry is in recession at present, it is still very promising," the fan manufacturer told Science News on condition of anonymity. 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 successful development of high-power wind turbines and various new 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 land and offshore wind power, but these achievements do not mean that the manufacturing technology of wind turbines in China is fully mature. "There is still a certain gap between domestic manufacturers and world-class main 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 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 power 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, pursue more intelligence. That is, smart grid and energy storage technology are combined to intelligently manage wind farms according to grid demand and wind energy. Third, be friendly, such as community-friendly, environment-friendly and grid-friendly. In addition, we should continue to expand the application of wind power generation, so that wind power generation can be better linked with other industries, such as hydrogen production, ammonia production and seawater desalination. In recent years, the Chinese government 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 impressive.
