How should China's power companies get rid of wind power and "discard the wind"?

On October 17th, wind power generation can provide both power protection and environmental protection. However, in recent years, the phenomenon of abandoned wind power in China has become more and more intense, and has become the most important issue affecting the development of the industry. In response to this, the officials of the National Energy Administration said in a statement that it will take two to three years to solve the wind problem.

The so-called abandonment of wind refers to the phenomenon that wind turbines are under normal conditions, and the wind turbines in some wind farms are suspended due to insufficient local power grid acceptance capacity, unmatched construction period of wind farms, and unstable wind power.

Wang Jun, Director of the New Energy Division of the National Energy Administration, stated at the 2013 Beijing International Wind Energy Conference on the 16th that it is expected that by the end of this year, the installed capacity of wind power in the country will exceed 75 million kilowatts, and the power generation will reach 140 billion kilowatt-hours. However, due to the lack of coordinated planning for all types of power supply and the low level of wind power grid-connected operation technology, the curtailment of wind curtailment is still occurring, and some places are still relatively serious.

According to the “China Wind Power Development Report 2013” ​​recently published by the China Resources Comprehensive Utilization Association’s Renewable Energy Professional Committee, the nation’s wind curtailment output that restricted wind power output in 2012 was approximately 20 billion kwh, which has doubled from 2011, accounting for 2012. The actual amount of wind power is 20% of the total. Among them, the Three North Region is particularly serious, and the winter heating period in Mengdong and Jilin even exceeds 50%.

Shi Dingyi, president of the China Renewable Energy Society, said that the issue of wind dispersal not only seriously affected the economic benefits of power generation companies, but also led to a large amount of energy wastage in consultation with wind power investment, leading to low investment and environmental benefits in the wind power industry.

The report pointed out that the difficulty in absorbing wind power is caused by the intermittent and volatile nature of wind power. However, at a deeper level, it is due to the fact that the volatility of new energy has not yet been made and the power system and policy mechanism have been made. On the adjustment caused.

In this regard, Wang Jun said that China is further improving the relevant policies to promote the reform of the power system, to achieve the full acquisition of wind power priority access to the Internet, the more severe areas of limited power, may implement a quota system for renewable energy power. Try to use two to three years to basically solve the problem of power curtailment.

Wang Jun said that in the future it is necessary to improve wind power development management system and optimize the development layout according to local conditions. With the rapid development of the technology of low-speed wind turbines in recent years, wind power development in China's central, eastern, and southern regions where electricity demand is large has formed a very considerable scale, which has created new growth points.

In addition, Shi Lishan, deputy director of the New Energy Division of the National Energy Administration, said that in the future, the scope of preparation resources should be further expanded, namely, the expansion of cross-regional transmission of electricity to allow wind power fluctuations to be absorbed in a larger grid system.

Shi Lishan also said that in order to truly promote the development of wind power on a larger scale, we must also rationalize our energy management system. At present, all types of energy in China are very closed. Electricity cannot be stored, but heat can be stored. How to coordinate the relationship between power supply and heating is important for solving the current volatility of wind power. significance. Shi Lishan said.

At the same time, in the context of shrinking domestic demand, Shi Pengfei, deputy director of the Wind Energy Professional Committee of the Chinese Renewable Energy Society, suggested that domestic wind power equipment manufacturers should actively develop overseas markets by virtue of their own advantages. China's wind power equipment manufacturers have the advantages of low cost and diversified products. It is expected that the volume of wind turbines that have been exported to foreign countries has reached 1 million kilowatts.

Shi Dingxi also stated that at present, China's main wind power market is in the country, and hopes that wind power can also go to the world like photovoltaics. Therefore, it is necessary to strengthen international cooperation and exchanges and actively explore the international market, especially the emerging markets.
