"Twelfth Five-Year" Wind Power Attending Incorporation "Indigestion"

"The latest data show that by the end of 2010, the total installed capacity of wind power in China has reached 41.627 million kilowatts, which is a 62% increase from the year-ago period in 2009, surpassing that of the United States for the first time (as of the end of 2010, the total installed capacity of wind power in the United States reached 40 million kilowatts), and thus formally It became the world's largest wind power installation." On January 12, Li Junfeng, deputy director of the Energy Research Institute of the National Development and Reform Commission, announced at the "Celebration of China's Wind Power Installation Leaping to the World's First Press Conference." According to reports, China has become a global leader in wind power installations.

During the “Eleventh Five-Year Plan” period, China’s wind power installations brought together the “scale effect” of the development of China’s wind power industry. However, at the beginning of the “Twelfth Five-Year Plan”, more and more people in the industry called for the increase in installed-digital growth. Pay attention to the quality of future development of wind power. This voice has gradually been responded to by policy makers. At the “Renewable Energy Development Review and Outlook 2011” forum held on January 12, Liang Zhipeng, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, said that in recent years, the country has strongly supported the development of wind power industry, wind power technology. And equipment manufacturing, and related economic issues have been solved in succession, the first task in the next five years is to pay close attention to the study of the power market integration of wind power and eliminate the problem of wind power and other renewable energy power generation to break the Internet bottlenecks.

“Quality” and “Quality” have re-emerged as the tone for development In the context of “Great Leap Forward” for wind power installations, the emphasis on development quality has undoubtedly injected a “spring breeze” for the sound development of China's wind power industry. In fact, at the National Energy Work Conference held on January 6, when Zhang Guobao, the then director of the National Energy Administration, talked about the “12th Five-Year Plan” of wind power development, he repeatedly mentioned “installation on the grid”. The words “power generation capacity” clearly exceeded the limitations of the single installed capacity figures in the “Eleventh Five-Year Plan” for renewable energy.

Liang Zhipeng said that the construction of power grids has lagged far behind the objective fact of wind power installed capacity, and increasingly demanded that the industry think about how much wind power can be consumed in the next five years under the constraint of the electricity market.

According to a study report issued by the State Grid, by 2015, the scale of grid-connected wind power grids that can absorb wind power will reach 100 million kilowatts by the end of 2015, and 150 million kilowatts by 2020. In the "12th Five-Year Plan" of the National Energy Administration, it is also proposed that by the end of 2015, the installed capacity of wind power should reach 90 million to 100 million kilowatts. Liang Zhipeng said that the target of 90 million kilowatts is the installed capacity of the grid. Some industry insiders believe that this is clearly a policy development party's consideration from the perspective of development quality. In order to avoid the phenomenon of “digestion” of wind power connected to the grid at the time, the rational positioning of the installed capacity is proposed, if it is simply to double according to the current average annual growth. With the development of speed, the installed capacity in 2015 will soar to 150 million kilowatts.

Electric power transmission has started to be laid out but some experts have pointed out that the 100-kilowatt electric network dissipating capacity is only a technically feasible goal, and specific implementation may be full of uncertainties due to the constraints of the grid system and the market-suppression mechanism. In this regard, Junfeng Li told the “China Energy News” reporter that this would require the state to clearly define the electricity market for wind power transmission across the region on the basis of wind power construction and power grid planning and formulate corresponding transmission plans. “For the moment, the most important thing to do is to approve the plans for the construction of a large-scale wind power transmission corridor for large-scale wind power bases planned by countries such as Mengdong Mengxi, Jiuquan of Gansu, and Hami of Xinjiang.” He said that at present, Mengdong The wind power in Mengxi is only lost to Hebei and Beijing as far as possible. The wind power in Jiuquan, Gansu is only transported to Lanzhou and Xi'an. The scale of market consumption is still very limited. According to the 2011 work plan of the National Energy Administration, a new batch of new projects including 5 million kilowatts of Gansu Jiuquan Phase II, 2 million kilowatts of Hami Xinjiang, and 2 million kilowatts of Inner Mongolia Kailu will be opened this year. The demand for the base's wind power delivery plan has become even more urgent.

In order to avoid possible "indigestion problems", the National Energy Work Conference in 2011 has started to propose ideas for planning wind power transmission. The reporter learned from the National Energy Administration that the basic considerations in the current policy are: Hebei and Mengxi wind power bases are mainly sent to the North China power grid in the near future, and Shandong Power Grid will need to receive some power and electricity before and after 2020. Mengdong Wind Power Base was recently sent to the northeast and north China power grids. Gansu Jiuquan Wind Power Base and Xinjiang Hami Base were recently sent to the Northwest Network and sent to Huazhong Network in the near future.

However, besides emphasizing increasing the scale of cross-regional consumption of wind power, the “12th Five-Year Plan” of energy planning, “focusing on the transformation and utilization of wind power on the spot and expanding the way of local consumption of wind power” has been mentioned many times. Liang Zhipeng said that according to research conducted by relevant parties, in a large region, if 10 million kilowatts of wind power installed capacity can guarantee 70% of the power generated, it can basically meet the market demand for capacity. According to this analysis, industry experts believe that the remaining 30% will fall into the local consumption category and will not be included in the delivery plan. On the issue of local consumption, Liang Zhipeng pointed out that the current consensus is that in the low-load period of the grid, in order to ensure that the wind turbine can operate at full capacity, it is possible to try to import such as electrolytic aluminum, coal chemical, and agricultural pumping irrigation. The enterprises make full use of this part of the low valley electricity, and give appropriate discounts on the price of electricity.

Liang Zhipeng revealed that the research on the market mechanism of wind power grid-connected consumption organized by the National Energy Administration in various regions and related enterprises and industry research institutes has started since the second half of last year, focusing on exploring the market mechanism of wind power online access from the perspective of technology and policy. The results of the system will be released later, and will become the policy basis for the future resolution of wind power.

The request for tariff adjustment highlights the issue of resolving wind power grid connection issues. The "Renewable Energy Law (Amendment)", which was implemented in July last year, and the "Regulations on the Management of Renewable Energy Power Generation Quota" formulated by the implementation of the bill are also considered to be a major factor. Sharp weapon. The reporter learned from the interview that there is no specific timetable for the publication of this document. In terms of increasing wind power generation indicators, power generation companies seem to be generally underpowered.

Yang Xiaosheng, chief engineer of Guodian Longyuan Power Group, said that in addition to the constraints of technology and national policies on wind power grid integration, the human factors encountered at the local level are even more hindered. He said that the arbitrariness and exclusivity of some local governments in approving projects made wind power developers such as Longyuan Group often encounter the vicious competition of local companies and the incompatibility of local grids on grid connection issues. Increased the cost of power generation for wind power generation companies and the difficulty of grid integration.

In order to further improve the power generation enterprises to improve wind power generation indicators, Yang Xiaosheng suggested that based on the determination of wind power on-grid tariffs based on the four types of resource zones, further adjust the wind power on-grid tariffs.

In response, authoritative wind power expert Shi Pengfei said in an interview with a reporter from China Energy News that the reduction in the actual development benefits of wind power due to difficulties in wind power integration and wind curtailment, as well as the new VAT system, have resulted in local development of wind energy resources. The decrease in revenue gained, which in turn increases the cost of wind power development and other factors, makes the current wind power policy environment has undergone major changes. Therefore, Shi Pengfei said that in the future, it is necessary to formulate corresponding reasonable electricity prices according to the actual development of wind power, continue to maintain a stable market demand, and establish an effective "cost-price" benefit-sharing mechanism.
