China's wind power industry "catch up with the wind"

On April 15, the State Grid Corporation of China released the White Paper of the State Grid Corporation of China on Wind Power Development. Shi Lishan, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, told the media at the press conference that the development potential of the Chinese wind power market is huge, especially with the launch of offshore wind power development, the wind power industry will enter the age of large units.

Wind power enters sustainable development

During the "Eleventh Five-Year Plan" period, China's wind power installed capacity doubled in five consecutive years, and the total installed capacity ranked first in the world. At the same time, the voice questioning the development of wind power also rang at this time. Some people said that the wind power industry was "overheated". According to the China Wind Power Installation Capacity Statistics released by the China Wind Energy Association (China Wind Energy Professional Committee), in 2010, 12,904 new wind turbines were installed in the Chinese mainland, with an installed capacity of 18,927.99 MW, a year-on-year increase of 73.3%. With an installed capacity of 44,733.29 MW, it surpasses the United States and ranks first in the world. At the same time, difficulties in the integration of wind power have arisen and the issue of wind erosion has become increasingly severe.

According to the “Twelfth Five-Year Plan” research report issued by CEC, the development of China’s wind power industry is in line with the trend of low-carbon industry development advocated by the international community, and is also in line with the direction of China’s energy-saving emission reduction and industrial restructuring. State-supported strategic new industries. There is indeed an overheating problem in China's wind power equipment manufacturing industry, and there are phenomena such as “scattered” and “chaos” in the layout of production plants. From the cost of power generation, with the rapid development of China's wind power equipment industry and the ever-increasing market competition, the cost of wind power development is being drastically reduced, and its economic and market competitiveness have been continuously improved. The cost of power generation from well-operated wind farms has been Close to coal electricity.

China's energy consumption is dominated by coal, and the resulting resources and environmental pressure are very high. In particular, the issue of coal transportation and carbon dioxide emissions is very prominent. The task of energy structure adjustment is arduous. At present, the development of nuclear power has been more restricted, and the impact of the accident at the Fukushima nuclear power plant in Japan is difficult to eliminate for a time. Speeding up the development and utilization of new energy is an important measure to adjust the energy structure. On the whole, wind power is the most mature technology in the field of new energy power generation. At present, more than 70 countries and regions in the world have begun to use wind energy to generate electricity. Some regions in Europe even use wind power as one of the major power generation methods. The fact that wind power has developed rapidly in recent years in China also proves this point.

Wind power market has great potential

The national “Twelfth Five-Year Plan” outlines that “accommodate the requirements of large-scale cross-regional power transmission and new energy generation and grid connection, and accelerate the construction of a modern power grid system”. At the same time, it also proposed to "strengthen the construction of grid-connected projects and effectively develop wind power." The State Grid Corporation of China has also clearly stated that accelerating the construction of UHV power grids and strong smart grids, and consuming wind power on a wider scale, all parties concerned are working hard to solve the new problems faced by wind power development, and this problem will be gradually solved effectively.

For the "scattered" and "chaotic" problems in the equipment manufacturing industry for the wind power industry, the past two years have also begun to change in the right direction. The China Investment Advisor released "Investment Analysis and Prospect Forecast Report for China's Wind Power Industry from 2010 to 2015" shows that in the fierce market competition, the degree of concentration of China's wind power equipment manufacturing industry has been further enhanced and the company's strength has been continuously enhanced. All these will lay the foundation for the “healthy and sustainable” development of China's wind power industry in the “Twelfth Five-Year Plan”. Shi Lishan said that at present, wind power development in China mainly focuses on land, and offshore wind power development has just started last year. According to the development plan, China will build 5 million kilowatts of offshore wind turbines during the 12th Five-Year Plan period. In other words, China’s wind power construction will enter a new phase of “both sea and land development and comprehensive development”. The National Weather Service's assessment of wind energy resources shows that China's wind energy resources of 70 meters above sea level reach 2.6 billion kilowatts. There are no specific assessment data for offshore wind energy resources, but there are also hundreds of millions of kilowatts of preliminary analysis. China's wind energy resources are very abundant. By the end of 2010, China's installed capacity of wind power is 44.73 million kilowatts, which is less than 2% of the total amount of wind energy that can be developed. . In this regard, the potential of China's wind power development market is extremely impressive.

The arrival of the era of large wind turbines

In recent years, China's wind power has not only grown rapidly in terms of installed capacity, but also the power of stand-alone machines is increasing. From a global perspective, with the rapid development of the wind power industry, wind power manufacturing technology levels continue to increase, and the stand-alone capacity of wind turbines is also increasing. The trend of high-power wind turbines is actually the result of scientific and technological progress. In the 1990s, "kilowatt" wind turbines dominated the market. After 2000, the manufacturing technology of "megawatt" turbines became more and more mature and the market share continued to expand. Especially in recent years, with the start of the development of offshore wind power, large megawatt-class units have begun to gain favor in the market.

According to the White Paper, high-power generating units can not only improve wind energy conversion efficiency, but also reduce the unit power cost of wind power generation, thereby reducing the operation and maintenance costs of wind farms, thereby improving the market competitiveness of wind power. Therefore, the "large-scale" wind turbines conform to the development direction of the wind power industry. The rise of China's wind power manufacturing industry must be attributed to the support of national policies and the rapid development of the wind power market. Secondly, it should be attributed to the company's own technological innovation, especially independent innovation in large unit R&D.

Although the issue of “dispersion” and “chaotic” has not yet been fundamentally solved, despite the occasional accidents in equipment quality in individual areas, overall, the concentration of wind power manufacturing industry in China continues to increase, wind power supporting industries continue to grow, and the wind power industry chain is growing Perfection, core competitiveness has been greatly enhanced, and wind power equipment manufacturing industry is moving in a healthy direction. This will be an important support force for the healthy and sustainable development of China's wind power industry in the “Twelfth Five-Year Plan” period.

Shi Lishan: Large wind power needs to be integrated into the big grid

"China's wind energy resources and load centers are in a reverse distribution. This basic national situation determines that China must develop wind power in a large-scale manner, and must take the road of building large bases and integrating into large power grids." April 15, New Energy and Energy of the National Energy Administration Shi Lishan, deputy director of the Department of Renewable Energy, said.

Shi Lishan expressed this point of view at the announcement of the State Grid Corporation's release of the "State Grid Corporation White Paper for Wind Power Development." He said that the integration of large wind power into large power grids is an inevitable choice for large-scale development of wind power in China. The large power grid can make full use of the complementarity of wind power in different regions and smoothly handle the fluctuations brought about by the wind power grid connection, which is conducive to the safe and stable operation of the power system.

It is understood that the state has planned to build eight million-million-kilowatt wind power bases. To meet the smooth access of large-scale wind power bases to the large power grids, the State Grid Corporation of China plans to build UHV power grids as backbone grids, coordinated development of power grids at all levels, with information, automation, and interactive features, safe and reliable, cost-effective, clean and environmentally friendly, Transparent, open, friendly and interactive strong smart grid.

Research shows that by strengthening the construction of cross-regional power grids and constructing the "Three Chinas" power grid, the nation's ability to absorb wind power can be more than doubled. By 2015, the scale of wind power consumption in China will exceed 90 million kilowatts. By 2020, the scale of wind power consumption in China will exceed 150 million kilowatts.
