“After several years of rapid development, China’s wind power development has achieved remarkable results, but there are also many contradictions and problems. Among them, the power market constraint has become the biggest obstacle to the healthy development of wind power in China.” National Energy Administration New Energy and Shi Lishan, Deputy Director of the Renewable Energy Division said.

Shi Lishan made the above remark at the 2012 China Wind Energy Tea Party held in Beijing recently. He disclosed that the national wind power work conference will be held after the Spring Festival. The meeting will focus on how to promote the sustained and healthy development of China's wind power industry to conduct focused discussions and special deployment.

“Cold thinking, we have a lot of problems with wind power.”

Shi Lishan pointed out that 2011 is an “extremely extraordinary year” for wind power development in China. On the one hand, the achievements have attracted worldwide attention; on the other hand, the contradictions and problems are also very prominent. For example, the wind turbines, wind towers collapsed, and wind power was operated on a large scale. Off the net and so on.

"Cold thinking, we really have a lot of problems in wind power." Shi Lishan said, "First, disorderly competition and blind development, whether it is the layout of the project or equipment manufacturing, lack of scientific planning and overall arrangements, some companies even disregard the market environment Inadequate development of technology, regardless of technical conditions; Second, the industrial enterprise management is extensive, industry technical standards and management requirements are not strict enough, some companies to grab resources, the project as the main goal, not enough attention to technology and quality, especially for future operations, resulting in Wind farm accidents occur frequently; Third, difficulties in grid connection and wind disposal are very prominent."

Shi Lishan believes that these problems are closely related to the immature development of wind power and unregulated industry management.

According to reports, it may be that these contradictions and problems were recognized. In 2011, the National Energy Administration did a lot of active exploration in strengthening industry management, including planning and management of wind power approved projects, more support for decentralized wind power development, forced certification of wind turbine equipment, and wind power. Field forecasting, wind power heating market demonstration and so on. In addition, a lot of research has also been carried out, including the study of wind power market absorption and grid connection issues, wind power quota policy research, and so on.

However, Shi Lishan admits that although the above exploration of the National Energy Administration has achieved some results, there is no qualitative change in the environment faced by wind power development, and it is difficult to achieve major breakthroughs in the near future. Among them, the most prominent problem is that the power market has become more and more restrictive for the development of wind power, that is, wind power operation is difficult to become the biggest obstacle to the healthy development of the wind power industry.

“To solve the problems faced by wind power development, it is imperative to deepen the reform of the power system.” Shi Lishan emphasized that “at present, the power system operation is still mainly based on planned measures, and relevant government departments still need to formulate power generation plans for power plants, transmission and distribution. There is no separation between electricity and electricity, electricity prices cannot reflect market supply and demand, resource characteristics, and lack of independence in power dispatch, and it is difficult to achieve fairness and justice.In order to deepen the reform of the power system, we must form an open, fair and transparent market environment, which will promote new energy sources such as wind power. The development is very necessary. This system should be open between regions, electricity prices should be able to reflect the relationship between supply and demand, environmental costs and natural characteristics, scheduling principles should also be fair and transparent."

A set of data from the industry confirms Shi Lishan’s judgment that the annual wind power generation in China is expected to be around 70 billion kWh in 2011, despite an increase of 40% compared with 50.1 billion kwh in 2010, but with 2010 Compared with the growth rate of wind power generation of 81.41% compared with the previous year, the growth rate of wind power generation in 2011 has dropped sharply. Some analysts believe that the main reasons for this situation are: the difficulty of grid connection and wind curtailment caused by the current power system.

"Wind power is a special product and must first solve the market problem."

“Under the market economy, the market is the basis for industrial development and product production. Only by developing the market can the industry develop, and products can be sold.” Shi Lishan said, “Wind power is a new industry and it is also a special product. First of all, to solve the market problem, it is necessary to develop the wind power market as the focus of future work."

Shi Lishan said that the main weakness of wind power is the random and intermittent nature of resources, and the development of wind power must solve this problem. From now on, there are several ways to resolve the instability of wind power: First, expand the scale of the power grid and dilute the instability of wind power; second, rationally configure the power supply structure and implement reasonable compensation; and third, develop and adapt to the characteristics of wind power. Electric load; fourth is to build large-scale power storage facilities.

"If we can operate across regional networks, China's wind power can certainly be greatly developed." According to Shi Lishan, by the end of 2011, China's total installed power capacity has reached 1.05 billion kilowatts, and its large scale of wind power consumption can be imagined. . However, wind power has indeed encountered market restrictions in some places.

Talking about the impact of energy storage technology development on the wind power market, Shi Lishan believes that in the near term, large-scale energy storage technologies are mainly pumped storage, and in the long run, there are more energy storage facilities—such as electric vehicles. and many more. The power load that is applicable to the characteristics of wind power is currently the most effective electricity supply. Because heat is also an important form of end-use energy, we now consume a lot of energy every year for heating. Heat can be stored. The key now is to look at the economics of this kind of electric heating. The compensation operation of thermal power and wind power is technically no problem. The key is a reasonable mechanism. A mechanism should be established to solve the problem of “fire” and “wind” compensation and create a better environment for the development of new energy.

“Therefore, in the event of a major change in the power management system, we should actively explore the wind power market and realize the compensation operation with other units.” Shi Lishan said that the construction of wind power should be linked to thermal power. In a certain power system, especially in a wind power centralized power system, any investor who wants to build wind power must have the necessary thermal power, and in the actual operation, the thermal power generator should assume the compensation operation. When the wind power is large, the thermal power To reduce the load accordingly. Hope this is the same interest body.

"Of course, there will be better results from the participation of hydropower." Shi Lishan added that "the key to the problem is to form a good compensation mechanism for compensation in wind power, hydropower and thermal power."

"The development of wind power in China has reached a time of comprehensive assessment."

After years of rapid development, China has become a veritable wind power in the world. At the same time, some problems in the development of the wind power industry continue to be exposed. In this regard, Shi Lishan pointed out: The development of wind power in China has reached a time of comprehensive assessment.

In a nutshell, how do we transform from a wind power country to a wind power power? How can wind power industry achieve sustainable and healthy development? In short, what is the design of our wind farm? What is the quality and performance of wind turbines? What is the state of operation and management of wind farms? What kind of indicators to evaluate? Shi Lishan said that all this needs to strengthen industry assessment.

He believes that the promotion of wind power development should also rely mainly on the power of the wind power industry, to establish a correct concept of wind power development.

First of all, we must establish a long-term perspective and lay a solid foundation for development. Wind power is an emerging industry. It is based on major technological breakthroughs and major development needs. It has important ties for the overall economic and social development and long-term development. It is also an industry with intensive knowledge and technology, low consumption of material resources, high growth potential, and comprehensive benefits. This means that its development must focus on the long-term, not just for the sake of the present. The current situation is mainly to lay the foundation, to truly establish brand awareness, and to win with quality and service.

Second, we must establish a sense of risk and choose a good technical line for the development of wind power. The key to the long-term healthy development of the wind power industry is the reliability and advancement of wind power equipment technology. In recent years, our wind turbine manufacturing industry has advanced by leaps and bounds. Many large wind turbine manufacturers are developing and producing wind turbines of 2 megawatts, 3 megawatts, 5 megawatts, or even more, and adopt different technical routes and direct drive. Double-fed; three-blade, two-blade; horizontal axis, vertical axis. It should be said that our wind turbines have not yet been tested for enough time, and there is still a great potential for systemic risks. Therefore, our wind turbine manufacturing companies and wind power investment companies must all have a sense of risk and must play steadily.

Third, we must speed up the management of the wind power industry, especially to improve the level of information and digital management. Informatization and digitization are the core of modern management. For wind power, digitalization of wind energy resources, digitization of wind power equipment, and digitalization of wind farm management must speed up the realization of informatization of wind power from site selection, design, construction and operation management. Digital management.
