How far is China from a real wind power country?

According to the latest data, the cumulative installed capacity of China Wind Power in 2010 reached 41.827 million kW, surpassing the United States as the world’s largest installed country. At the same time, wind power generated only 50 billion kilowatt-hours, which is still lower than that of the United States. The grid-connected capacity is only about 30% of the lifting capacity, which is far below the international level, and has seriously affected the improvement of wind power efficiency and efficiency.

China's wind power industry has experienced rapid development in the past five years. In five years, it has achieved the development process of the developed countries in Europe and America in the past 30 years. While the industry continues to progress in the rapid development of the market scale, the challenges and problems it faces are also obvious. . First of all, the quality level of China's wind power equipment, including equipment availability, power generation capacity, etc., has yet to be improved. Second, the difference between grid-connected capacity and lifting capacity is still far behind the international advanced level. How to transform from a large installed country to a large country using wind power has become China's biggest problem currently facing it. On the other hand, the integration of wind power into the grid is the top priority in solving this problem.

First of all, the development speed of wind power exceeds everyone's expectations, and the construction of power grids is conducted in accordance with the routine. This makes it impossible for the power grid construction based on the national wind power development plan to meet the demand for rapid development of wind power. There is a serious disconnect between wind power and power grids in terms of planning and construction. This is exactly the cause of the current bottleneck in wind power integration.

Secondly, as a kind of intermittent power source, wind power has inherent insufficiency in stability, and this feature is also the main reason why the grid lacks interest in wind power. Although the Renewable Energy Law requires that the grid purchase full renewable energy power generation, the Eleventh Five-Year Plan for Renewable Energy Development issued in 2008 also clearly requires that grid companies receive 1% and 3% of the total in 2015 and 2020 respectively. Renewable energy power generation, but these regulations have not yet been implemented, even if the grid does not have access to renewable energy has not been punished. In this zero-burden situation, the willingness of grid companies to accept wind power is also reduced to zero. The penalty mechanism failed. The “Renewable Energy Law” and the National Development and Reform Commission’s implementation rules for cost sharing all provide certain compensation for the acquisition of wind power by grid companies, and the part of the grid that builds capacity to accept wind power may enter cost accounting, but these revenues Compared with the total revenue of a highly monopolistic company, the power grid is almost negligible and is simply not enough to motivate the grid to actively accept wind power.

At a deeper level, the development of wind power business in the United States and Europe for the past 30 years is based on a more mature free electricity market. It fully utilizes market mechanisms and administrative measures to solve various problems in the development of wind power. However, the development of China's electricity market is still not mature, and basic functions such as optimizing resource allocation, technology development, benefit distribution, and micro-equilibrium are still lacking. Although the electricity price subsidy policy based on electricity is implemented for renewable energy power generation, the current electricity price mechanism fails to reflect the power quality and real-time market prices of various types of power generation projects, and the cost sharing system fails to compensate for the increased cost of electricity operation. Between the renewable energy generation and conventional power systems, there will be issues of cost sharing and market competition in the grid construction and power dispatch. It can be said that the current obsolescence of the power system has constrained the healthy growth of the renewable energy market.
