Decentralized development of the hottest wind powe

Decentralized development of wind power industry will become a trend

for example, on the morning of May 19, after five years of continuous doubling, wind power generation in the first quarter was 18.8 billion kwh, an increase of 60.4% year-on-year. The development of wind power has entered a transition period. Vigorously developing offshore wind power and decentralized development have become a new trend

doubled for five consecutive years

wind power generation in the first quarter was 18.8 billion kwh, an increase of 60.4% year-on-year. This growth rate is 30-50 percentage points higher than that of thermal power, hydropower and nuclear power, ranking first among major energy power generation

Shi Lishan, deputy director of the renewable energy and new energy department of the national energy administration, told Sina Finance and economics that this achievement was mainly due to the rapid growth of wind power scale for consecutive years

at present, seven ten million kW wind power bases in Gansu Jiuquan, Mengdong, Mengxi, northeast, Hebei, Xinjiang, Jiangsu and Shandong are also under planning and construction. Statistics show that the total installed capacity of wind power in China has doubled for five consecutive years since 2005. By the end of 2010, the cumulative installed capacity had reached 41.827 million KW, of which 31 million KW had been installed and generated electricity, surpassing the United States for the first time and ranking first in the world

the general environment of domestic economic development has laid a good foundation for the development of wind power. Last year, the subsidy for renewable energy power generation was as high as 12billion yuan. Even five years ago, it was impossible to allocate so much funds to support renewable energy. Xie Jianning, director of Shenhua Guohua Energy, concluded that the transformation of economic and social environment, market-oriented operation mode and policy support are the key factors for the development of wind power

between, the state determined 49 wind farm projects through five phases of concession bidding, and the market-oriented operation successfully reduced the price of wind power; Driven by the development of wind power and the advance of equipment, the domestic fan manufacturing level has been improved and the equipment manufacturing cost has been greatly reduced. Tao Gang, vice president of Sinovel wind power, revealed that since 2005, the installed price of wind turbines per kW has fallen from 7000 yuan to less than 3800 yuan. For wind turbines of the same technical grade, the price of domestic fans is 20% lower than that of imported ones

in addition, in the first quarter, this "graphene high molecular composite artificial skin" has entered the clinical trial stage in the Burn Research Institute of Southwest Hospital. Another factor contributing to the surge in electricity generation is the large-scale merger of Jiuquan, the first ten million kilowatt wind power base, last year. It is reported that last year, only tens of thousands of kilowatts of generator units were put into operation in the base; In contrast, by the end of April this year, 3.874 million kW power generating units had been centralized and put into operation on a large scale

variation of wind power development

although Jiuquan base has been solved, the problem is still the biggest growth trouble faced by wind power. Xiechangjun, general manager of Guodian Longyuan Power, revealed that the monthly electricity rationing of Longyuan accounted for 16% of the total, while the high proportion of regional electricity rationing in Inner Mongolia reached 40%

according to the data from Guohua wind power, the company lost more than 100million kwh of wind power in 2009, more than 300million kwh in 2010, and more than 250million kwh in this month. Especially in Tongliao area, the abandoned electricity is far greater than the combined electricity. Xie Jianning, chairman of Shenhua Guohua Energy, revealed that, to make matters worse, the scale of arrears in wind power sales revenue continues to expand, testing the capital chain of wind power developers

the three northern regions, which are rich in wind power resources, have weak electricity and low demand for electricity. With the increase of wind power, the space of remaining power transmission capacity has been almost filled. New wind power requires new power transmission channels. However, power construction is later than the development of wind power, and the UHV transmission channel of the national power planning is still in the long approval process

in order to promote the large-scale development of wind power, in the past, it was advocated to establish large bases and integrate large power, but now it is more hoped that on this basis, it will support areas with less abundant resources, develop low wind speed wind farms, and advocate decentralized development. Shi Lishan, deputy director of the renewable energy and new energy department of the national energy administration, revealed the change of this policy thinking

he said that this does not mean giving up the original big base route, but walking on two legs, so that enterprises can not only focus on big bases but also on the whole country. Yunnan, Anhui, Hubei, Hunan, Shandong, Shanxi, Chongqing, Guizhou, Tibet and Sichuan all have such conditions. The advantage of decentralized wind power development is that less power investment; At the same time, it is in the power load center and will not be affected by power rationing

this development idea has also been recognized by the enterprise. Xie Changjun, general manager and Deputy Secretary of the Party group of Guodian Longyuan Power Group Co., Ltd., said that the next step of wind power needs to change from the pursuit of development to quality, from the pursuit of installed capacity to the pursuit of electricity. We have slowed down the pace of development in Inner Mongolia and Northeast China and turned to Shanxi, Jiangsu, Yunnan, Shanxi and other places. The first domestic low wind speed electric field built by Longyuan Power in Anhui has been fully commissioned in April

offshore wind power has become a new direction of development

Shi Lishan revealed that another direction of wind power development in China in the future is to develop offshore wind power. Last year, the national development and Reform Commission led the first round of offshore wind power bidding, which the industry believes is a sign of starting offshore wind power development. Jiangsu, Zhejiang and Shanghai are all building offshore wind power projects, and have planned 10 million KW offshore wind power projects

after the onshore wind power resources were carved up, all wind power developers also focused on offshore wind power. He Yan, executive director and deputy general manager of Huaneng new energy, said that the development of offshore wind power in the eastern coastal areas is close to the power load center and has advantages. At the same time, offshore wind power has the advantage of generating Jinan experimental machine, which is characterized by long power time

however, the development of offshore wind power faces construction difficulties and high risks. Last year, the bid winning price of offshore wind power was close to that of onshore wind power, so the project start-up faced many problems. At present, what developers most hope to introduce is the electricity price and support policies for offshore wind power

in addition, due to the disturbance of offshore wind power development to the seabed, it involves coastal development, maritime transportation, military going to sea and other issues, and involves coordination with the maritime safety administration, military, transportation and other departments. Shi Lishan said that he would explore the approval process of offshore wind power as soon as possible
